Introduction

The S8/T8 chassis is a global TV chassisfor the model year 2001 and is used for TV sets with

screen sizesfrom 25” - 36” (large screen), in Super Flat,Real Flat and Wide Screen executions.

The standard architecture consists of a Main panel, aPicture Tube panel, a Side I/O panel and

a Top Controlpanel. In some executions, a Picture In Picture (PIP) panel is used.

The Main panel consists primarily of conventional components withhardly any surface mounted

devices.

The functions for video processing, microprocessor (μP)and teletext (TXT) decoder are

combined in one IC (TDA958xH), theso-called Ultimate One Chip (UOC). This chip is (surface)

mountedon the copper side of the LSP.

The S8/T8 is divided into 2 basic systems, i.e.mono and stereo sound. While the audio

processing for the mono soundis done in the audio block of the UOC, an external audio

processingIC is used for stereo sets.

The tuning system features 181 channels with on-screen display.The main tuning system uses

a tuner, a microcomputer, and a memoryIC mounted on the main panel.

The microcomputer communicates with the memory IC, the customerkeyboard, remote

receiver, tuner, signal processor IC and the audiooutput IC via the I Cbus. The memory IC

retains the settings for favorite stations, customer-preferredsettings, and service / factory data.

The on-screen graphics and closed caption decoding aredone within the microprocessor, and

then sent to the signal processorIC to be added to the main signal.

The chassis utilizes a Switching Mode Power Supply (SMPS) forthe main voltage source. The

chassis has a ‘hot’ ground referenceon the primary side and a cold ground reference on the

secondaryside of the power supply and the rest of the chassis.

Audio Signal Processing

Block diagram Audio

Stereo

In stereo sets, the signal goes via the SAWfilter (position 1002), to the audio demodulator part

of the UOCIC 7200. The audio output on pin 48 goes to the stereo decoder 7831or 7861. The

switch inside this IC selects either the internal decoderor an external source.

There are two stereo decoders used:

1. a BTSC DBXstereo/SAP decoder (MSP34X5 at position 7831) for the highestspecified

sets and

2. a BTSC non-DBX stereo decoder (TDA 9853 at position 7861)for BTSC Economic.

The output is fed to the to the audio amplifier (AN7522at position 7901). The volume level is

controlled at this IC (pin9) by a control line (VolumeMute) from the microprocessor. The

audiosignal from 7901 is then sent to the speaker / headphone outputpanel.

Mono

In mono sets, the signal goes via the SAW filter(position 1002), to the audio demodulator part

of the UOC IC 7200.The audio output on pin 48 goes, via the smart sound circuit (7941for

Bass and 7942 for Treble) and buffer 7943, to the audio amplifier(AN7523 at position 7902).

The volume level is controlled at this IC (pin 9) by a ‘VolumeMute’ controlline from the

microprocessor.

The audio signal from IC 7902 is then sent to the speaker / headphoneoutput panel.

Video Signal Processing

Introduction

The video signal-processing path consists ofthe following parts:

RF signalprocessing.

Video source selection.

Video demodulation.

Luminance / Chrominance signal processing.

RGB control.

RGB amplifier

The processing circuits listed above are all integratedin the UOC TV processor. The

surrounding components are for the adaptationof the selected application. The I Cbus is for

defining and controlling the signals.

RF signal processing

7/8/2004

SPMS

Page 5 of 32

The incoming RF signal goes to the tuner (pos.1000), where the 45.75 MHz IF signal is

developed and amplified.The IF signals then exits the tuner from pin 11 to pass throughthe

SAW filters (pos. 1002). The shaped signal is then applied to theIF processor part of the UOC

(pos. 7200).

Tuner AGC (Automatic Gain Control) will reduce the tunergain and thus the tuner output

voltage when receiving strong RF signals.Adjust the AGC takeover point via the Service

Alignment Mode (SAM).The tuner AGC starts working when the video-IF input reaches a

certaininput level. Adjust this level via the I C bus. The tuner AGCsignal goes to the tuner

(pin 1) via the open collector output (pin22) of the UOC.

The IC also generates an Automatic Frequency Control (AFC) signal that goes to the tuning

system via the I C bus, to provide frequencycorrection when needed.

The demodulated composite video signal is available atpin 38 and then buffered by transistor

7201.

Video source selection

The Composite Video Blanking Signal (CVBS)from buffer 7201 goes to the audio carrier trap

filters (1200, 1201,or 1202 depending on the system used) to remove the audio signal.

Thesignal then goes to pin 40 of IC 7200. The internal input switchselects the following input

signals:

Pin 40: terrestrialCVBS input

Pin 42: external AV1 CVBS input

Pin 44: external Side I/O CVBS or AV2Luminance (Y) input

Pin 45: external AV2 Chrominance (C) input

Figure:

Once the signal source is selected, a chroma filter calibrationis performed. The received color

burst sub-carrier frequency is usedfor this. Correspondingly, the chroma band pass filter for

PAL/NTSCprocessing or the cloche filter for SECAM processing is switchedon. The selected

luminance (Y) signal is supplied to the horizontaland vertical synchronization processing circuit

and to the luminanceprocessing circuit. In the luminance-processing block, the

luminancesignal goes to the chroma trap filter. This trap is switched "on" or "off" dependingon

the color burst detection of the chroma calibration circuit.

The group delay correction part can be switched betweenthe BG and a flat group delay

characteristic. This has the advantagethat in multi-standard receivers no compromise has to

be made forthe choice of the SAW filter.

Video demodulation

The color decoder circuit detects whether thesignal is a PAL, NTSC or SECAM signal. The

result is made knownto the auto system manager. The PAL/NTSC decoder has aninternal

clock generator, which is stabilized to the required frequency byusing the 12 MHz clock signal

from the reference oscillator of themicrocontroller / teletext decoder.

The base-band delay line is used to obtain a good suppression ofcross color effects.

The Y signal and the delay line outputs U and V are appliedto the luminance / chroma signal

processing part of theTV processor.

Luminance / Chrominance signalprocessing

The output of the YUV separator is fed to theinternal YUV switch, which switches between the

output of the YUV separatoror the external YUV (for DVD or PIP) on pins 51-53. Pin 50 is

theinput for the insertion control signal called ‘FBL-1’. Whenthis signal level becomes higher

than 0.9 V (but less than 3 V),the RGB signals at pins 51, 52 and 53 are inserted into the

pictureby using the internal switches.

Also some picture improvement features are implementedin this part:

Black stretch This functioncorrects the black level of incoming signals, which have a

differencebetween the black level and the blanking level. The amount of extension

dependsupon the difference between actual black level and the darkest partof the

incoming video signal level. It is detected by means of aninternal capacitor.

White stretch Thisfunction adapts the transfer characteristic of the luminance amplifierin

a non-linear way depending on the average picture content ofthe luminance signal. It

operates in such a way that maximum stretching isobtained when signals with a low

video level are received. For brightpictures, stretching is not active.

Dynamic skintone correction This circuit corrects (instantaneouslyand locally) the hue of

those colors which are located in the areain the UV plane that matches the skin tone.

The correction is dependenton the luminance, saturation and distance to the preferred

axis.

The YUV signal is then fed to the color matrix circuit,which converts it to R, G and B signals.

The OSD/TXT signal from the microprocessor ismixed with the main signal at this point, before

being output tothe CRT board (pins 56, 57 and 58).

Picture in picture (if present)

The PIP controller M65669FP is an NTSC videoprocessor for TV applications. It contains all of

the analog signalprocessing, control logic and memory, necessary to provide sub-picture

insertionfrom a second, non-synchronized, video source into the main pictureof the TV. This

can be an external source (via the rear I/Oinputs) or the video signal of the tuner.

Sync signals are derived from the sandcastle signal and separatedby circuit 7171-7174 on the

PIP-interface, and then fed to pins32 and 33 of the PIP processor 7803.

RGB control

The RGB control circuit enables the pictureparameters contrast, brightness and saturation to

be adjusted, byusing a combination of the user menus and the remote control.

Additionallyautomatic gain control for the RGB signals via cut-off stabilizationis achieved in this

functional block to obtain an accurate biasingof the picture tube. Therefor this block inserts the

cut-off pointmeasuring pulses into the RGB signals during the vertical retraceperiod.

7/8/2004

SPMS

Page 8 of 32

The following additional controls are used:

Black current calibration loop Becauseof the 2-point black current stabilization circuit,

both the blacklevel and the amplitude of the RGB output signals depend on the

drivecharacteristics of the picture tube. The system checks whether thereturning

measuring currents meet the requirements, and adapt theoutput level and gain of the

circuit when necessary. After stabilizationof the loop, the RGB drive signals are switched

on. The 2-pointblack level system adapts the drive voltage for each cathode insuch a

way that the two measuring currents have the right value. Thisis done with the

measurement pulses during the frame flyback. Duringthe first frame, three pulses with a

current of 8 μA aregenerated to adjust the cut off voltage. During the second frame,three

pulses with a current of 20 μA are generated to adjustthe ‘white drive’. This has as a

consequence,that a change in the gain of the output stage will be compensatedby a gain

change of the RGB control circuit. Pin 55 (BLKIN) of theUOC is used as the feedback

input from the CRT base panel.

Blue stretch Thisfunction increases the color temperature of the bright scenes

(amplitudeswhich exceed a value of 80% of the nominal amplitude).This effect is

obtained by decreasing the small signal gain of thered and green channel signals, which

exceed this 80% level.

Beam currentlimiting A beam current limiting circuit inside the UOChandles the contrast

and brightness control for the RGB signals.This prevents the CRT from being overdriven,

which could otherwisecause serious damage in the line output stage. The reference

usedfor this purpose is the DC voltage on pin 54 (BLCIN) of the TV processor.Contrast

and brightness reduction of the RGB output signals is thereforeproportional to the voltage

present on this pin. Contrast reductionstarts when the voltage on pin 54 is lower than 2.8

V. Brightnessreduction starts when the voltage on pin 54 is less than 1.7 V.The voltage

on pin 54 is normally 3.3 V (limiter not active). Duringset switch-off, the black current

control circuit generates a fixedbeam current of 1 mA. This current ensures that the

picture tubecapacitance is discharged. During the switch-off period, the verticaldeflection

is placed in an over-scan position, so that the dischargeis not visible on the screen.

RGB amplifier

From outputs 56, 57 and 58 of IC 7200 the RGBsignals are applied to the integrated output

amplifier (7330) onthe CRT panel. Via the outputs 7, 8 and 9 the picture tube cathodesare

driven.

The supply voltage for the amplifier is +200V and is derived from the line output stage.

Synchronization

7/8/2004

SPMS

Page 9 of 32

Inside IC 7200 part D the vertical and horizontalsync pulses are separated. These ‘H’ and ‘V’

signalsare synchronised with the incoming CVBS signal. They are then fedto the H- and V-

drive circuits and to the OSD/TXT circuitfor synchronization of the On Screen Display and

Teletext (CC)informationrmation.

Deflection

Horizontal drive

The horizontal drive signal is obtained froman internal VCO, which is running at twice the line

frequency. Thisfrequency is divided by two, to lock the first control loop to theincoming signal.

When the IC is switched ‘on’, the ‘Hdrive’ signalis suppressed until the frequency is correct.

The ‘Hdrive’ signal is available atpin 30. The ‘Hflybk’ signal is fed to pin 31 tophase lock the

horizontal oscillator, so that Q7462 cannot switch ‘on’ duringthe flyback time.

The ‘EWdrive’ signal for the E/Wcircuit (if present) is available on pin 15, where it drives

transistor7400 to make linearity corrections in the horizontal drive.

When the set is switched on, the ‘+8V’ voltagegoes to pin 9 of IC 7200. The horizontal drive

starts up in a softstart mode. It starts with a very short T

time of the horizontaloutput

transistor. The T

ofthe transistor is identical to the time in normal operation. Thestarting

OFF

frequency during switch on is therefore about 2 times higherthan the normal value. The ‘on’

time is slowlyincreased to the nominal value in 1175 ms. When the nominal valueis reached,

the PLL is closed in such a way that only very smallphase corrections are necessary.

The ‘EHTinformation’ line on pin 11is intended to be used as a ‘X-ray’ protection.When this

protection is activated (when the voltage exceeds 6 V),the horizontal drive (pin 30) is switched

"off" immediately.If the ‘H-drive’ is stopped, pin 11 will become lowagain. Now the horizontal

drive is again switched on via the slowstart procedure.

The ‘EHTinformation’ line (Aquadag)is also fed back to the UOC IC 7200 pin 54, to adjust the

picturelevel in order to compensate for changes in the beam current.

The ‘filament’ voltage is monitoredfor ‘no voltage’ or ‘excessive voltage’.This voltage is rectified

by diode 6447 and fed to the emitter oftransistor 7443. If this voltage goes above 6.8 V,

transistor 7443will conduct, making the ‘EHT0’ line ‘high’.This will immediately switch off the

horizontal drive (pin 30) viathe slow stop procedure.

The horizontal drive signal exits IC 7200 at pin 30 andgoes to 7462, the horizontal driver

transistor. The signal is amplified andcoupled to the base circuit of 7460, the horizontal output

transistor.This will drive the line output transformer (LOT) and associatedcircuit. The LOT

provides the extra high voltage (EHT), the VG2voltage and the focus and filament voltages for

7/8/2004

SPMS

the CRT, while theline output circuit drives the horizontal deflection coil.

Vertical drive

A divider circuit performs the vertical synchronization.The vertical ramp generator needs an

external resistor (R3245, pin 20)and capacitor (C2244, pin 21). A differential output is

availableat pins 16 and 17, which are DC-coupled with the vertical outputstage.

During the insertion of RGB signals, the maximum vertical frequencyis increased to 72 Hz so

that the circuit can also synchronize onsignals with a higher vertical frequency like VGA.

To avoid damage of the picture tube when the vertical deflectionfails, the guard output is fed to

the beam current limiting input.When a failure is detected the RGB-outputs are blanked. When

novertical deflection output stage is connected this guard circuitwill also blank the output

signals.

These ‘V_DRIVE+’ and ‘V_DRIVE-‘ signalsare applied to the input pins 1 and 2 of IC 7471 (full

bridge verticaldeflection amplifier). These are voltage driven differential inputs.As the driver

device (IC 7200) delivers output currents, R3474 and R3475convert them to voltage. The

differential input voltage is comparedwith the voltage across measuring resistor R3471 that

provides internalfeedback information. The voltage across this measuring resistoris

proportional to the output current, which is available at pins4 and 7 where they drive the

vertical deflection coil (connector0222) in phase opposition.

IC 7471 is supplied by +13 V. The vertical flybackvoltage is determined by an external supply

voltage at pin 6 (VlotAux+50V).This voltage is almost totally available as flyback voltage

acrossthe coil, this being possible due to the absence of a coupling capacitor(which is not

necessary, due to the ‘bridge’ configuration).

Deflection corrections

The linearity correction

A constant voltage on the horizontal deflectioncoil should result in a sawtooth current. This

however is not thecase as the resistance of the coil is not negligible. In order tocompensate for

this resistance, a pre-magnetised coil L5457 is used.R3485 and C2459 ensure that L5457

does not excite, because of its ownparasite capacitance. This L5457 is called the "linearity

coil".

The Mannheim effect

When clear white lines are displayed, the high-voltagecircuit is heavily loaded. During the first

half of the flyback,the high voltage capacitors are considerable charged. At that pointin time,

the deflection coil excites through C2465. This current peak,through the high-voltage capacitor,

distorts the flyback pulse.This causes synchronisation errors, causing an oscillation underthe

7/8/2004

SPMS

white line.

During t3 - t5, C2490//2458 is chargedvia R3459. At the moment of the flyback, C2490//2458is

subjected to the negative voltage pulses of the parabola as aresult of which D6465 and D6466

are conducting and C2490//2458is switched in parallel with C2456//2457. Thisis the moment

the high-voltage diodes are conducting. Now extraenergy is available for excitation through

C2465 and the line deflection. Asa consequence the flyback pulse is less distorted.

The S-Correction

Since the sides of the picture are furtheraway from the point of deflection than from the centre,

a linearsawtooth current would result in a non-linear image being scanned(the center would be

scanned slower than the sides). For the center-horizontal line,the difference in relation of the

distances is larger then thosefor the top and bottom lines. An S-shaped current will have to

besuperimposed onto the sawtooth current. This correction is calledfinger-length correction or

S-correction.

C2456//2457 is relatively small, asa result of which the sawtooth current will generate a

parabolicvoltage with negative voltage peaks. Left and right, the voltageacross the deflection

coil decreases, and the deflection will slowdown; in the center, the voltage increases and

deflection is faster.The larger the picture width, the higher the deflection current

throughC2456//2457. The current also results in a parabolic voltageacross C2484//2469,

resulting in the fingerlength correctionproportionally increasing with the picture width. The

east/westdrive signal will ensure the largest picture width in the centerof the frame. Here the

largest correction is applied.

East/West correction

In the T8, there are three types of CRTs, namelythe 100º, 110º and wide screen CRTs. The

100º CRTis raster-correction-free and does not need East/West correction.

The 110º 4:3 CRT comes with East/Westcorrection and East/West protection.

The wide screen TV sets have all the correction of the110 4:3 CRT and also have additional

picture format like the 4:3format, 16:9, 14:9, 16:9 zoom, subtitle zoom and the Super-Wide

pictureformat

A line, written at the upper- or lower side of the screen,will be larger at the screen center when

a fixed deflection currentis used. Therefore the amplitude of the defelection current must

beincreased when the spot approaches the center of the screen. Thisis called the East/West or

pincushion correction.

The ‘Ewdrive’ signal from pin 15 ofIC 7200 takes care for the correct correction. It drives FET

7400.It also corrects breathing of the picture, due to beam current variations(the EHT varies

dependent of the beam current). This correctionis derived from the ‘EHTinformation’ line.

7/8/2004

SPMS

Page 12 of 32

Two protections are built-in for the E/W circuit:over-current and over-voltage protection. See

paragraph 9.3.5.

Panorama

The panorama function is only used in 16:9sets. This is a function to enable the 4:3 and Super-

Wide feature.It drives the ‘Bass_panorama’ line, toactivate relay 1400. When this relay is

switched on, the capacitors2453//2454 are added in parallel to the defaultS-correction

capacitors 2456//2457. This results inan increased capacitance, a lower resonance frequency

of the linedeflection coil and the S-correction capacitors and therefore aless steep S-corrected

line deflection current.

Power Supply

Introduction

The supply is a Switching Mode Power Supply(SMPS). The frequency of operation varies with

the circuit load.This ‘Quasi-Resonant Flyback’ behavior has someimportant benefits compared

to a ‘hard switching’ fixedfrequency Flyback converter. The efficiency can be improved up

to90%, which results in lower power consumption. Moreoverthe supply runs cooler and safety

is enhanced.

The power supply starts operating when a DC voltage goes fromthe rectifier bridge via T5520,

R3532 to pin 8. The operating voltagefor the driver circuit is also taken from the ‘hot’ sideof this

transformer.

The switching regulator IC 7520 starts switching the FET ‘on’ and ‘off’,to control the current

flow through the primary winding of transformer5520. The energy stored in the primary winding

during the ‘on’ timeis delivered to the secondary windings during the ‘off’ time.

7/8/2004

SPMS

Page 14 of 32

The ‘MainSupply’ line is the referencevoltage for the power supply. It is sampled by resistors

3543 and3544 and fed to the input of the regulator 7540 / 6540.This regulator drives the

feedback optocoupler 7515 to set the feedbackcontrol voltage on pin 3 of 7520.

The power supply in the set is ‘on’ anytime AC power goes to the set.

Derived Voltages

The voltages supplied by the secondary windingsof T5520 are:

‘MainAux’ forthe audio circuit (voltage depends on set execution, see table below),

3.3 V and 3.9 V for the microprocessor and

‘MainSupply’ for the horizontaloutput (voltage depends on set execution, see table

below).

Other supply voltages are provided by the LOT. It supplies +50 V(only for large screen sets),

+13 V, +8 V, +5V and a +200 V source for the video drive. The secondaryvoltages of the LOT

are monitored by the ‘EHTinformation’ lines.These lines are fed to the video processor part of

the UOC IC 7200on pins 11 and 34.

This circuit will shut ‘off’ the horizontaldrive in case of over-voltage or excessive beam current.

Degaussing

When the set is switched on, the degaussingrelay 1515 is immediately activated as transistor

7580 is conducting.Due to the RC-time of R3580 and C2580, it will last about 3 to 4

secondsbefore transistor 7580 is switched off.

Basic IC Functionality

For a clear understanding of the Quasi-Resonantbehavior, it is possible to explain it by a

simplified circuit diagram(see Figure below). In this circuit diagram, the secondary sideis

transferred to the primary side and the transformer is replacedby an inductance L .C is the

totaldrain capacitance including the resonance capacitor C , parasitic output capacitorC

OSS

of the MOSFETand the winding capacitance C ofthe transformer. The turns ratio of the

transformer is representedby n (N /N ).

In the Quasi-Resonant mode each period can be dividedinto four different time intervals, in

chronological order:

Interval 1: t0 < t < t1primary stroke At the beginning of the first interval,the MOSFET is

switched ‘on’ and energy is storedin the primary inductance (magnetization). At the end,

the MOSFETis switched ‘off’ and the second interval starts.

Interval 2:t1 < t < t2 commutation time In thesecond interval, the drain voltage will rise

from almost zero to V +n•(V

derivative, correspondingto V /L , to a negative derivative, correspondingto -n•V

/L .

OUT

Interval 3:t2 < t < t3 secondary stroke In thethird interval, the stored energy is transferred

to the output,so the diode starts to conduct and the inductive current I will decrease. In

otherwords, the transformer will be demagnetized. When the inductivecurrent has

become zero the next interval begins.

Operation

The supply can run in three different modesdepending on the output power:

Quasi-Resonant mode (QR) TheQR mode, described above, is used during normal

operation. Thiswill give a high efficiency.

Frequency Reductionmode (FR) The FR mode (also called VCO mode) is implementedto

decrease the switching losses at low output loads. In this waythe efficiency at low output

powers is increased, which enables powerconsumption smaller than 3 W during stand-

by. The voltage at thepin 3 (Ctrl) determines where the frequency reduction starts.

Anexternal Ctrl voltage of 1.425 V corresponds with an internal VCOlevel of 75 mV. This

fixed VCO level is called V

active in this mode.

Minimum Frequencymode (MinF) At VCO levels below 50 mV, the minimum

frequencywill remain on 6 kHz, which is called the MinF mode. Because ofthis low

frequency, it is possible to run at very low loads withouthaving any output regulation

problems.

Safe-Restart Mode

This mode is introduced to prevent the componentsfrom being destroyed during eventual

system fault conditions. Itis also used for the Burst mode. The Safe-Restart mode will be

enteredif it is triggered by one of the following functions:

Over voltageprotection,

Short winding protection,

Maximum ‘on time’ protection,

reachingUVLO level (fold back during overload),

Detecting a pulse for Burst mode,

Over temperature protection.

When entering the Safe-Restart mode, the output driveris immediately disabled and latched.

The V winding will not chargethe V capacitoranymore and the V voltagewill drop until

UVLO is reached. To recharge the V

capacitor, the internalcurrent source (I

)

(restart)(VCC)

will be switched ‘on’ to initiate a new start-upsequence as described before. This Safe-Restart

mode will persistuntil the controller detects no faults or burst triggers.

Standby

The set goes to Standby in the following cases:

After pressingthe ‘standby’ key on the remote control.

When the set is in protection mode.

In Standby, the power supply works in ‘burstmode’.

Burst mode can be used to reduce the power consumption below1 W at stand-by. During this

mode, the controller is active (generatinggate pulses) for only a short time and for a longer

time inactivewaiting for the next burst cycle.

In the active period the energy is transferred to thesecondary and stored in the buffer capacitor

in front of the linear stabilizer(see Figure below). During the inactive period, the load

STAB

(e.g. microprocessor)discharges this capacitor. In this mode, the controller makes useof the

Safe-Restart mode.

7/8/2004

SPMS

Page 21 of 32

Figure:

The system enters burst mode standby when the microprocessoractivates the ‘Stdby_con’ line.

Whenthis line is pulled high, the base of Q7541 is allowed to go high.This is triggered by the

current from collector Q7542. When Q7541 turns ‘on’,the opto-coupler (7515) is activated,

sending a large current signalto pin 3 (Ctrl). In response to this signal, the IC stops

switchingand enters a ‘hiccup’ mode. This burst activationsignal should be present for longer

than the ‘burst blank’ period(typically 30 μs): the blanking time prevents false bursttriggering

due to spikes.

Burst mode standby operation continues until the microcontrollerpulls the ‘Stdby_con’ signal

low again.The base of Q7541 is unable to go high, thus cannot turn ‘on’.This will disable the

burst mode. The system then enters the start-upsequence and begins normal switching

behavior.

For a more detailed description of one burst cycle, threetime intervals are defined:

t1: Discharge of V

when gate drive is active During thefirst interval, energy is

transferred, which result in a ramp-upof the output voltage (V

)in front of the

STAB

stabilizer. When enough energy is stored in thecapacitor, the IC will be switched ‘off’ by

acurrent pulse generated at the secondary side. This pulse is transferredto the primary

side via the opto coupler. The controller will disablethe output driver (safe restart mode)

when the current pulse reachesa threshold level of 16 mA into the Ctrl pin. A resistor R

(R3519) is placed inseries with the opto coupler, to limit the current going into theCtrl pin.

Meanwhile the V

capacitoris discharged but has to stay above V

UVLO

t2: Dischargeof V

when gate drive is inactive During thesecond interval, the V

7/8/2004

isdischarged to V

.The output voltage will decrease depending on the load.

UVLO

t3: Charge ofV

when gate drive is inactive Thethird interval starts when the UVLO is

reached. The internal currentsource charges the V

capacitor(also the soft start

capacitor is recharged). Once the V

capacitor is chargedto the start-up voltage, the

driver is activated and a new burstcycle is started.

Figure:

Protection Events

The SMPS IC 7520 has the following protectionfeatures:

Demagnetization sense

This feature guarantees discontinuous conductionmode operation in every situation. The

oscillator will not starta new primary stroke until the secondary stroke has ended. Thisis to

ensure that FET 7521 will not turn on until the demagnetization oftransformer 5520 is

complete.The function is an additional protectionfeature against:

saturationof the transformer,

damage of the components during initial start-up,

an overload of the output.

The demag(netization) sense is realized by an internalcircuit that guards the voltage (Vdemag)

at pin 4 that is connectedto V winding byresistor R (R3522). The Figure below shows the

circuit and the idealized waveformsacross this winding.

7/8/2004

SPMS

Page 23 of 32

Figure:

Over Voltage Protection

The Over Voltage Protection ensures that theoutput voltage will remain below an adjustable

level. This worksby sensing the auxiliary voltage via the current flowing into pin4 (DEM) during

the secondary stroke. This voltage is a well-defined replicaof the output voltage. Any voltage

spikes are averaged by an internalfilter.

If the output voltage exceeds the OVP trip level, theOVP circuit switches the power MOSFET

‘off’.

Next, the controller waits until the ‘under voltagelock out‘ level (UVLO = ± 9 V) is reachedon

pin 1 (V

).This is followed by a safe restart cycle, after which switchingstarts again. This

process is repeated as long as the OVP conditionexists. The output voltage at which the OVP

function trips, is setby the demagnetization resistor R3522.

Over Current Protection

The internal OCP protection circuit limitsthe ‘sense’ voltage on pin 5 to an internal level.

Over Power Protection

7/8/2004

SPMS

Page 24 of 32

During the primary stroke, the rectified ACinput voltage is measured by sensing the current

drawn from pin4 (DEM). This current is dependent on the voltage on pin 9 of transformer

5520and the value of R3522. The current informationrmation is used toadjust the peak drain

current, which is measured via pin I

SENSE

Short Winding Protection

If the ‘sense’ voltage onpin 5 exceeds the short winding protection voltage (0.75 V),

theconverter will stop switching. Once V drops below the UVLOlevel, capacitor C2521 will

be recharged and the supply will startagain. This cycle will be repeated until the short circuit is

removed(safe restart mode). The short winding protection will also protectin case of a

secondary diode short circuit.

This protection circuit is activated after the leadingedge blanking time (LEB).

LEB time

The LEB (Leading Edge Blanking) time is aninternally fixed delay, preventing false triggering of

the comparatordue to current spikes. This delay determines the minimum ‘on’ timeof the

controller.

Over Temperature protection

When the junction temperature exceeds the thermalshutdown temperature (typ. 140º C), the

IC will disablethe driver. When the V

voltagedrops to UVLO, the V

capacitorwill be

recharged to the V

level.If the temperature is still too high, the V

voltage will drop

(start)

againto the UVLO level (Safe-Restart mode). This mode will persist untilthe junction

temperature drops 8 degrees typically below the shutdowntemperature.

Mains dependent operation enabling level

To prevent the supply from starting at a lowinput voltage, which could cause audible noise, a

mains detectionis implemented (Mlevel). This detection is provided via pin 8, thatdetects the

minimum start-up voltage between 60 and 100 V. As previous mentioned,the controller is

enabled between 60 and 100 V.

An additional advantage of this function is the protection againsta disconnected buffer

capacitor (C ).In this case, the supply will not be able to start-up because theV

capacitor

willnot be charged to the start-up voltage.

Figure:

Introduction

The microprocessor part of the UOC, has thecomplete control and teletext on board. User

menu, Service DefaultMode, Service Alignment Mode and Customer Service Mode are

generatedby the μP. Communication to other ICs is done via the I C-bus.

I 2 C-Bus

The main control system, which consists ofthe microprocessor part of the UOC (7200), is

linked to the externaldevices (tuner, NVM, MSP, etc) by means of the I C-bus. An internalI

C-bus is usedto control other signal processing functions, like video processing,sound IF,

vision IF, synchronization, etc.

User Interface

The S8/T8 uses a remote control withRC5 protocol. The incoming signal is connected to pin 67

of theUOC.

The "Top Control" keyboard, connectedto UOC pin 80, can also control the set. Button

7/8/2004

SPMS

Page 26 of 32

recognition is donevia a voltage divider.

The front LED (6691) is connected to an output controlline of the microprocessor (pin 5). It is

activated to provide theuser information about whether or not the set is working correctly

(e.g.,responding to the remote control, normal operation (USA only) orfault condition)

In- And Output Selection

For the control of the input and output selections,there are three lines:

STATUS1 This signal providesinformationrmation to the microprocessor on whether a

video signalis available on the SCART1 AV input and output port (only for Europe).

Thissignal is not connected in NAFTA sets.

STATUS2 Thissignal provides informationrmation to the microprocessor on whethera

video signal is available on the SCART2 AV input and output port(only for Europe). For

sets with an SVHS input it provides the additional informationrmationif a Y/C or CVBS

source is present. The presence of anexternal Y/C source makes this line ‘high’ whilea

CVBS source makes the line ‘low’.

SEL-MAIN-FRNT-RR Thisis the source select control signal from the microprocessor.

Thiscontrol line is under user control or can be activated by the othertwo control lines.

Power Supply Control

The microprocessor part is supplied with 3.3V and 3.9 V both derived from the ‘MainAux’

voltagevia a 3V3 stabilizer (7560) and a diode.

Two signals are used to control the power supply:

Stdby_con This signalis generated by the microprocessor when over-current takes

placeat the ‘MainAux’ line. This is done to enablethe power supply into standby burst

mode, and to enable this modeduring a protection. This signal is ‘low’ undernormal

operation conditions and goes to ‘high’ (3.3V) under ‘standby’ and ‘fault’ conditions.

POWER_DOWN Thissignal is generated by the power supply. Under normal

operatingconditions this signal is ‘high’ (3.3 V). During ‘standby’ mode,this signal is a

pulse train of approx. 10 Hz and a ‘high’ durationof 5 ms. It is used to give information to

the UOC about the fault conditionin the Audio amplifier supply circuit. This information is

generatedby sensing the current on the ‘MainAux’ line (usingvoltage drop across R3564

to trigger Q7562). This signal goes ‘low’ whenthe DC-current on the ‘MainAux’ line

exceeds 1.6- 2.0 A. It is also used to give an early warning to the UOC abouta power

failure. Then the information is used to mute the soundamplifier to prevent a switch off

noise and to solve the switch-offspot.

Protection Events

Several protection events are controlled bythe UOC:

BC protection , to protect thepicture tube from a too high beam current. The UOC has the

capabilityof measuring the normal back level current during the vertical flyback.So if for

some reason the CRT circuit is malfunctioning (i.e. highbeam current), the normal black

current will be out of the 75 μArange, and the UOC will trigger the power supply to shut

down. However,this is a high beam-current situation, the TV screen will be brightwhite

before the set is shut down.

E/Wprotection , two protection mechanisms are built in, over-currentand over-voltage.

„

In case ofover-current due to defective parts in the line deflection outputstage, a

high current will flow through resistors 3405//3406.If this current is large enough to

create a voltage drop of 0.7V across 3405//3406, transistor Q7606 (in A7 diagram)

will conduct and pin 80 of the UOC will be pulled down. Thereafter,the UOC will

shut down the power supply. In case of further currentincrease, the fused resistor

3411 is built-in for double protection.

„

In case of a high voltage appearing across capacitor 2401(dependent of the tube

size), which is high enough to trigger zenerdiode 6401 into conduction, transistor

Q7606 (in A7 diagram) willconduct and UOC is triggered to shut down the power

supply.

I C protection , to check whetherall I C IC"sare functioning.

In case one of these protections is activated, the setwill go into ‘standby’.

The ‘on’ and ‘standby’ LEDsare controlled via the UOC.

ComPair

Introduction

ComPair (Computer Aided Repair) is a servicetool for Philips Consumer Electronics products.

ComPair is a further developmentof the DST (special remote control transmitter for Service),

whichallows faster and more accurate diagnostics. ComPair has three bigadvantages:

ComPair helpsyou quickly get an understanding on how to repair the chassis ina short

time by guiding you systematically through the repair procedures.

ComPair allows very detailed diagnostics (onI2C level) and is therefore capable of

accurately indicating problem areas.You do not have to know anything about I2C

commands yourself becauseComPair takes care of this.

ComPair speeds up the repair time since it can automaticallycommunicate with the

chassis (when the microprocessor is working)and all repair information is directly

available. When ComPair isinstalled together with the Force electronic manual of the T8

chassis,schematics and CBAs are only a mouse-click away.

Specifications

ComPair consists of a Windows based faultfindingprogram and an interface box between PC

7/8/2004

SPMS

Page 11 of 16

and the product. The ComPairinterface box is connected to the PC via a serial or RS232 cable.

In the case of the L01 chassis, the ComPair interfacebox and the TV communicate via a bi-

directional service cable viathe service connector (Connector 0267).

The ComPair faultfinding program is able to determinethe problem of the television set.

ComPair can gather diagnostic informationin two ways:

Automatic(by communication with the television): ComPair can automaticallyread the

contents of the entire error buffer. Diagnosis is doneon I2C level. ComPair can access

the I2C bus of the television.ComPair can send and receive I2C commands to the

microprocessorof the television. In this way, it is possible for ComPair to communicate

(read and write) to devices on the I2C busses of the TV-set.

Manually (by asking questions to the servicer): Automatic diagnosis is only possible if the

microprocessor of the televisionis working correctly, and only to a certain extent. When

this isnot the case, ComPair will guide you through the faultfinding treeby asking you

questions (for example; Does the screen gives a picture?Click on the correct answer:

YES / NO) and showing youexamples (for example; Measure test-point I7 and click on

the correct oscillogramyou see on the oscilloscope). You can answer by clicking on a link

(for example, text or a waveform picture) that will bring you tothe next step in the

faultfinding process.

By a combination of automatic diagnostics and an interactive questionand answer procedure,

ComPair will enable you to find most problemsin a fast and effective way.

Beside fault finding, ComPair provides some additional features like:

Uploadingor downloading of presets.

Management of preset lists.

If both ComPair and the Force electronic servicemanual are installed, all the schematics

and CBAs of the television setare available by clicking on the appropriate hyperlink.

Example:Measure the DC-voltage on capacitor C2568 (Schematic/Panel)at the

Monocarrier. Click on the "Panel" hyperlinkto automatically show the CBA with a

highlighted capacitor C2568.Click on the "Schematic" hyperlink to automatically show the

electronicposition of the highlighted capacitor.

How To Connect

1. Firstinstall the ComPair Browser software (see the Quick Reference Cardfor installation

instructions).

2. Connect the RS232 interface cable between afree serial (COM) port of your PC and the

PC connector (marked with "PC")of the ComPair interface.

3. Connect the AC power adapter to the supply connector (marked"POWER 9V DC") on the

ComPair interface.

7/8/2004

4. Switch the ComPair interface OFF.

5. Switch the television set OFF (and remove theAC power).

6. Connect the ComPair interface cable betweenthe connector on the rear side of the

ComPair interface (marked"I2C") and the ComPair connector on the mono carrier

(Connector0267).

7. Plug the AC power adapter in the AC power outletand switch on the ComPair interface.

The green and red LEDs lightup together. The red LED turns off after approximately 1

Error Buffer

The error code buffer contains all errors detectedsince the last time the buffer was erased. The

7/8/2004

SPMS

Page 13 of 16

buffer is writtenfrom left to right. When an error occurs that is not yet in theerror code buffer, it

is displayed at the left side and all othererrors shift one position to the right.

How To Read The Error Buffer

You can read the error buffer in 3 ways:

On screenvia the SDAM (if you have a picture). Examples:

„

ERROR: 0 00 0 0 : No errors detected

ERROR: 6 0 0 0 0 : Error code 6 is the lastand only detected error

ERROR: 9 6 0 0 0 : Error code 6 was detectedfirst and error code 9 is the last

detected (newest) error

Via (when you have no picture). See "The BlinkingLED Procedure"

Via ComPair.

How To Clear The Error Buffer

Theerror code buffer is cleared in the following cases:

By using the CLEAR command in the SDAM menu:

„

To enter SDAM,Press the following key sequence on the remote control

transmitter:

„

0-6-2-5-9-6-MENU

Do not allow the display to time out betweenentries while keying the sequence.

Make sure the menu item CLEAR is highlighted.Use the MENU UP/DOWN buttons,

if necessary.

„

Press the MENU RIGHT button to clear the error buffer.The text on the right side of

the "CLEAR" line will change from"CLEAR?" to "CLEARED"

If the contents of the error buffer have notchanged for 50 hours, the error buffer resets

automatically.

Note:

If SDAM is exited by disconnecting the AC power from the televisionset, the error buffer is not

reset.

Error Codes

In case of non-intermittent faults, write downthe errors present in the error buffer and clear the

error bufferbefore you begin the repair.

This ensures that old error codes are no longer present.

If possible, check the entire contents of the error buffer.In some situations an error code is only

the result of another error andnot the actual cause of the problem (for example, a fault in

theprotection detection circuitry can also lead to a protection).

Note: Error 7 is not applicable.

TheBlinking LED Procedure

Using this procedure, you can make the contentsof the error buffer visible via the front LED.

This is especiallyuseful when there is no picture.

When the SDAM is entered, the LED will blink the contentsof the error-buffer:

1-12 shortblinks (indicates error number 1-12)

when all the error-codes are displayed, thesequence finishes with an "ON" LED blink of 3

seconds

the sequence starts again

Example of error buffer: 12 9 6 0 0

After entering SDAM, the following occurs:

12 shortblinks followed by a pause of 3 seconds

9 short blinks followed by a pause of 3 seconds

6 short blinks followed by a pause of 3 seconds

1 long "ON" blink of 3 seconds to finish thesequence

the sequence starts again.

Protections

If a fault situation is detected, an errorcode will be generated; and, if necessary, the television

set willgo in to protection mode. Blinking of the red LED at a frequencyof 3 Hz indicates the

protection mode. In some error cases, themicroprocessor does not put the set in protection

mode. The errorcodes of the error buffer and the blinking LED procedure can beread via the

Service Default Alignment Menu (SDAM), or via ComPair.

To get a quick diagnosis the chassis has two service modes implemented:

The CustomerService Mode (CSM).

The Service Default Alignment Mode (SDAM).

For a detailed description see Chapter 9 paragraphs 3.4and 4.5.

Repair Tips

Below some failure symptoms are given, followedby a repair tip.

Set is dead and makes hiccuping sound

"Main Power Supply" is available. Hiccupping stops when L5561is de-soldered, meaning

that problem is in the "Main Power Supply"line. No output voltages at LOT, no horizontal

deflection. Reason:line transistor 7460 is defective.

Set is dead,and makes no sound

Check power supply IC 7520. Result: voltage at pins 1,3, 4, 5 and 6 are about 180 V and

pin 8 is 0 V. The reason why thevoltage on these pins is so high is because the output

driver (pin6) has an open load. That is why MOSFET 7521 is not able to switch.Reason:

feedback resistor 3523 is defective. Caution : Be careful measuringthe gate of 7521;

circuitry is very high ohmic and can easily bedamaged!

Set is in hiccupmode and shuts down after 8 seconds Blinking LED (setis in SDAM

mode) indicates error 5. As it is unlikely that P "POR"and "+8V protection" happen at the

same time, measure the"+8V" supply. If this voltage is missing, check transistor7480.

Set is in non-stophiccup mode

Set is in over-current mode; check the secondary sensing (optocoupler 7515) and the

"Main Power Supply" voltage. Signal "Stdby_con"must be logic low under normal

operation conditions and goes tohigh (3.3 V) under standby and fault conditions.

Set turns on,but without picture and sound

The screen shows snow, but OSD and other menus are okay.Blinking LED procedure

indicates error 11, so problem is expectedin the tuner (part reference number 1000).

Check presence of supplyvoltages. "Vlotaux+5V" voltages at pin 5 and 7 are

okay;"VT_supply" at pin 9 is missing. Conclusion: resistor 3460is defective.

Set turns on,but with a half screen at the bottom. Sound is okay

Blinking LED (set is in SDAM mode) indicates error 3. Check"Vlotaux+11V" and "+50V".

If they are okay, problemis expected in the vertical amplifier IC 7471. Use an

oscilloscopeto measure the waveform on pin 17 of the UOC. Also measure the

waveformat pin 1 of IC 7471. If the signal there is missing, a defectiveresistor R3244

caused the problem

Safety & MaintenanceInstructions, Warnings,

And Notes

Safety Instructions For Repairs

Safety regulations require that during a repair:

Due to the ‘hot’ partsof this chassis, the set must be connected to the AC power via

anisolation transformer.

Safety components, indicated by the symbol ꢀ , should be replaced bycomponents

identical to the original ones.

When replacing the CRT, safety goggles mustbe worn.

Safety regulations require that after a repair, the setmust be returned in its original condition.

Pay particular attentionto the following points:

General repairinstruction: as a strict precaution, we advise you to re-solderthe solder

connections through which the horizontal deflection currentis flowing, in particular:

„

all pins ofthe line output transformer (LOT)

fly-back capacitor(s)

S-correction capacitor(s)

line output transistor

pins of the connector with wires to the deflectioncoil

other components through which the deflectioncurrent flows.

Note: This re-soldering is advised to prevent bad connections dueto metal fatigue in solder

connections and is therefore only necessaryfor television sets more than two years old.

Route thewire trees and EHT cable correctly and secure them with the mountedcable

clamps.

Check the insulation of the AC power cord forexternal damage.

Check the strain relief of the AC power cordfor proper function, to prevent the cord from

touching the CRT,hot components, or heat sinks.

Check the electrical DC resistance between theAC plug and the secondary side (only for

sets that have an isolated powersupply). Do this as follows:

1. Unplug theAC power cord and connect a wire between the two pins of the ACplug.

2. Turn on the main power switch (keep the AC power cordunplugged!).

3. Measure the resistance value between the pinsof the AC plug and the metal

shielding of the tuner or the aerialconnection of the set. The reading should be

7/8/2004

SPMS

Page 2 of 3

between 4.5 MΩ and12 MΩ.

4. Switch the TV OFF and remove the wire betweenthe two pins of the AC plug.

Check the cabinet for defects, to prevent thepossibility of the customer touching any

internal parts.

Maintenance Instructions

It is recommended to have a maintenance inspectioncarried out by qualified service personnel.

The interval dependson the usage conditions:

When theset is used under normal circumstances, for example in a livingroom, the

recommended interval is three to five years.

When the set is used in an environment withhigher dust, grease or moisture levels, for

example in a kitchen,the recommended interval is one year.

The maintenance inspection includes the followingactions:

1. Perform the "generalrepair instruction" noted above.

2. Clean the power supply and deflection circuitryon the chassis.

3. Clean the picture tube panel and the neck ofthe picture tube.

Warnings

Inorder to prevent damage to ICs and transistors, avoid all high voltageflashovers. In

order to prevent damage to the picture tube, usethe method shown in Fig. 2-1, to

discharge the picture tube. Usea high voltage probe and a multi-meter (position VDC).

Dischargeuntil the meter reading is 0 V (after approx. 30 s).

Figure:

All ICs andmany other semiconductors are susceptible to electrostatic discharges(ESD).

7/8/2004

SPMS

Page 3 of 3

Careless handling during repair can reduce life drastically.When repairing, make sure

that you are connected with the same potentialas the mass of the set by a wristband with

resistance. Keep componentsand tools also at this potential. Available ESD protection

equipment:

„

Complete kitESD3 (small tablemat, wristband, connection box, extension cable,and

ground cable) 4822 310 10671.

„

Wristband tester 4822 344 13999.

Together with the deflection unit and any multi-poleunit, flat square picture tubes form an

integrated unit. The deflectionand the multi-pole units are set optimally at the factory.

Adjustmentof this unit during repair is therefore not recommended.

Be careful during measurements in the high voltage sectionand on the picture tube.

Never replace modules or other components whilethe unit is switched ON.

When you align the set, use plastic rather thanmetal tools. This will prevent any short

circuits and the dangerof a circuit becoming unstable.

Notes

Measurethe voltages and waveforms with regard to the chassis (= tuner)ground (ꢁ/ ),

or hotground (ꢁ0 ), depending onthe area of circuitry being tested.

The voltages and waveforms shown in the diagramsare indicative. Measure them in the

Service Default Mode (see chapter5) with a color bar signal and stereo sound (L: 3 kHz,

R: 1 kHzunless stated otherwise) and picture carrier at 475.25 MHz (PAL)or 61.25 MHz

(NTSC, channel 3).

Where necessary, measure the waveforms and voltages with(ꢁ+ ) and without (ꢁ, )
