SECTION 1  
PRECAUTIONS  
(10) Isolation Check  
1.1 SAFETY PRECAUTIONS  
(Safety for Electrical Shock Hazard)After re-assembling the  
product, always perform an isolation check on the exposed metal  
parts of the cabinet (antenna terminals, video/audio input and output  
terminals, Control knobs, metal cabinet, screwheads, earphone jack,  
control shafts, etc.) to be sure the product is safe to operate without  
danger of electrical shock.  
(1) The design of this product contains special hardware, many circuits  
and components specially for safety purposes. For continued  
protection, no changes should be made to the original design unless  
authorized in writing by the manufacturer. Replacement parts must  
be identical to those used in the original circuits. Service should be  
performed by qualified personnel only.  
(2) Alterations of the design or circuitry of the products should not be  
made. Any design alterations or additions will void the manufacturer's  
warranty and will further relieve the manufacturer of responsibility for  
personal injury or property damage resulting therefrom.  
(3) Many electrical and mechanical parts in the products have special  
safety-related characteristics. These characteristics are often not  
evident from visual inspection nor can the protection afforded by them  
necessarily be obtained by using replacement components rated for  
higher voltage, wattage, etc. Replacement parts that have these  
special safety characteristics are identified in the parts list of Service  
manual. Electrical components having such features are  
identified by shading on the schematics and by ( ) on the parts  
list in Service manual. The use of a substitute replacement which  
does not have the same safety characteristics as the recommended  
replacement part shown in the parts list of Service manual may cause  
shock, fire, or other hazards.  
a) Dielectric Strength Test  
The isolation between the AC primary circuit and all metal  
parts exposed to the user, particularly any exposed metal part  
having a return path to the chassis should withstand a voltage  
of 1100V AC (r.m.s.) for a period of one second.  
(. . . . Withstand a voltage of 1100V AC (r.m.s.) to an appliance  
rated up to 120V, and 3000V AC (r.m.s.) to an appliance rated  
200V or more, for a period of one second.)  
This method of test requires test equipment not generally  
found in the service trade.  
b) Leakage Current Check  
Plug the AC line cord directly into the AC outlet (do not use a  
line isolation transformer during this check.). Using a "Leakage  
Current Tester", measure the leakage current from each  
exposed metal part of the cabinet, particularly any exposed  
metal part having a return path to the chassis, to a known good  
earth ground (water pipe, etc.). Any leakage current must not  
exceed 0.5mA AC (r.m.s.). However, in tropical area, this must  
not exceed 0.2mA AC (r.m.s).  
(4) Use isolation transformer when hot chassis.  
The chassis and any sub-chassis contained in some products are  
connected to one side of the AC power line. An isolation transformer  
of adequate capacity should be inserted between the product and the  
AC power supply point while performing any service on some  
products when the HOT chassis is exposed.  
Alternate Check Method  
Plug the AC line cord directly into the AC outlet (do not use  
a line isolation transformer during this check.). Use an AC  
voltmeter having 1000 ohms per volt or more sensitivity in  
the following manner. Connect a 1500ohm 10W resistor  
paralleled by a 0.15µF AC-type capacitor between an  
exposed metal part and a known good earth ground (water  
pipe, etc.). Measure the AC voltage across the resistor with  
the AC voltmeter. Move the resistor connection to each  
exposed metal part, particularly any exposed metal part  
having a return path to the chassis, and measure the AC  
voltage across the resistor. Now, reverse the plug in the AC  
outlet and repeat each measurement. Any voltage  
measured must not exceed 0.75V AC (r.m.s.). This  
corresponds to 0.5mA AC (r.m.s.).  
(5) Don't short between the LIVE side ground and ISOLATED  
(NEUTRAL) side ground or EARTH side ground when repairing.  
Some model's power circuit is partly different in the GND. The  
difference of the GND is shown by the LIVE : ( ) side GND, the  
ISOLATED(NEUTRAL) : ( ) side GND and EARTH : ( ) side GND.  
Don't short between the LIVE side GND and ISOLATED(NEUTRAL)  
side GND or EARTH side GND and never measure with a measuring  
apparatus (oscilloscope etc.) the LIVE side GND and  
ISOLATED(NEUTRAL) side GND or EARTH side GND at the same  
time.  
If above note will not be kept, a fuse or any parts will be broken.  
(6) The high voltage applied to the picture tube must conform with that  
specified in Service manual. Excessive high voltage can cause an  
increase in X-Ray emission, arcing and possible component damage,  
therefore operation under excessive high voltage conditions should  
be kept to a minimum, or should be prevented. If severe arcing  
occurs, remove the AC power immediately and determine the cause  
by visual inspection (incorrect installation, cracked or melted high  
voltage harness, poor soldering, etc.). To maintain the proper  
minimum level of soft X-Ray emission, components in the high  
voltage circuitry including the picture tube must be the exact  
replacements or alternatives approved by the manufacturer of the  
complete product.  
However, in tropical area, this must not exceed 0.3V AC  
(r.m.s.). This corresponds to 0.2mA AC (r.m.s.).

(7) If any repair has been made to the chassis, it is recommended that  
the B1 setting should be checked or adjusted (See ADJUSTMENT  
OF B1 POWER SUPPLY).  
(8) Do not check high voltage by drawing an arc. Use a high voltage  
meter or a high voltage probe with a VTVM. Discharge the picture  
tube before attempting meter connection, by connecting a clip lead to  
the ground frame and connecting the other end of the lead through a  
10k2W resistor to the anode button.  
(9) When service is required, observe the original lead dress. Extra  
precaution should be given to assure correct lead dress in the high  
voltage circuit area. Where a short circuit has occurred, those  
components that indicate evidence of overheating should be  
replaced. Always use the manufacturer's replacement components.  
(11) High voltage hold down circuit check.  
After repair of the high voltage hold down circuit, this circuit shall be  
checked to operate correctly.  
See item "How to check the high voltage hold down circuit".

3.8.4 DEFLECTION & CONVERGENCE ADJUSTMENT  
• The adjustment using the remote control unit is made on the basis of the initial setting values.  
• The setting values which adjust the screen to the optimum condition can be different from the initial setting values.  
• At first the adjustment in FULL mode should be done, then the data for the other ASPECT mode is corrected in the respective value  
at the same time.  
3.8.4.1 FLOWCHART OF ADJUSTMENT  
CAUTION:  
All adjustments of the DEFLECTION circuit for this model should be carried out under the status without convergence operation.  
To enter the mode without convergence operation, select 1.PICTURE/SOUND and change the data in the setting item F62 from 0  
to 1. (For details, please refer to the adjustment of DEFLECTION.)  
As a result, you can get the screen as shown in bellow figure. Adjust the DEFLECTION circuit in order of the steps indicated by the  
downward arrows.

TROUBLESHOOTING  
4.1 SELF CHECK FUNCTIONS  
• This model has self-check functions that inform of the failure of the TV by detecting abnormality.  
• Operational state is always monitored and the identified is memorized on the record.  
4.1.1 HOW TO ENTER THE SELF-CHECK MODE  
(1) Set the <SLEEP TIMER 30MIN> with [SLEEP TIMER] key.  
(Fig.1)  
SLEEP TIMER  
(2) During the <SLEEP TIMER 30MIN> display, press [DIS-  
30MIN  
PLAY] key and [VIDEO STATUS] key at the same time.  
(3) Then <TEST MODE> screen is displayed. (Fig.2)  
(4) Press [ 4 ] key then <SELF-CHECK> screen is appear.  
(Fig.3)  
4.1.2 HOW TO EXIT FROM THE SELF-CHECK MODE  
(1) By using the remote control unit, turn the power off. At this  
time, the failure record is cleared.  
(2) Take off the AC plug from the wall outlet. At this time, the  
failure record is not cleared.

4.1.3 SELF-CHECK DISPLAY  
The self-check results are shown on the following display.  
Method of indication when the raster is not displayed (Fig.3).

4.1.4 EXPLANATION FOR ACTIVATION OF SELF-CHECK  
FUNCTIONS  
• For X-ray protection, B1 over-current protection and low B  
short protection, the power of the TV is turned off if NG is de-  
tected.  
ITEM  
RESULT COUNT  
Immediately after the power is turned off, POWER LED will be  
turning on and off.  
When the power is turned off, you cannot turn the power on  
again until the AC plug is taken out and put in again.  
• The latest failure is stored on the record at the end.  
The failure record for each check item is counted to the num-  
ber of 9 at the maximum, When more than 9 failures are stored  
on the record, the counter remains stopped at 9.  
• SYNC is neither counted nor stored in memory.  
• Because of the timing of Vcc start-up and shut-down of the IC  
connecting to the I2C bus during which the power is turned on  
and off, the operation may be interpreted as an error.  
In order to avoid the misinterpretation, the self-check functions  
should be started at about 3 seconds after the power is turned  
on.
