Important Safety Precautions

Prior to shipment from the factory, JVC products are strictly inspected to conform with the recognized product safety and electrical codes of the

countries in which they are to be sold. However, in order to maintain such compliance, it is equally important to implement the following precautions

when a set is being serviced.

Precautions during Servicing

•

1. Locations requiring special caution are denoted by labels and in-

scriptions on the cabinet, chassis and certain parts of the product.

When performing service, be sure to read and comply with these

and other cautionary notices appearing in the operation and serv-

ice manuals.

12. Crimp type wire connector

In such cases as when replacing the power transformer in sets

where the connections between the power cord and power trans-

former primary lead wires are performed using crimp type connec-

tors, if replacing the connectors is unavoidable, in order to prevent

safety hazards, perform carefully and precisely according to the

following steps.

2. Parts identified by the ! symbol and shaded (

critical for safety.

) parts are

Replace only with specified part numbers.

1) Connector part number : E03830-001

2) Required tool : Connector crimping tool of the proper type which

will not damage insulated parts.

3) Replacement procedure

(1) Remove the old connector by cutting the wires at a point

close to the connector.

Note: Parts in this category also include those specified to com-

ply with X-ray emission standards for products using

cathode ray tubes and those specified for compliance

with various regulations regarding spurious radiation

emission.

Important : Do not reuse a connector (discard it).

3. Fuse replacement caution notice.

Caution for continued protection against fire hazard.

Replace only with same type and rated fuse(s) as specified.

4. Use specified internal wiring. Note especially:

1) Wires covered with PVC tubing

2) Double insulated wires

cut close to connector

3) High voltage leads

Fig.3

5. Use specified insulating materials for hazardous live parts. Note

especially:

(2) Strip about 15 mm of the insulation from the ends of the

wires. If the wires are stranded, twist the strands to avoid

frayed conductors.

1) Insulation Tape

2) PVC tubing

3) Spacers

4) Insulation sheets for transistors

5) Barrier

15 mm

6. When replacing AC primary side components (transformers, power

cords, noise blocking capacitors, etc.) wrap ends of wires securely

about the terminals before soldering.

Fig.4

(3) Align the lengths of the wires to be connected. Insert the

wires fully into the connector.

Fig.1

Metal sleeve

7. Observe that wires do not contact heat producing parts (heatsinks,

oxide metal film resistors, fusible resistors, etc.)

Connector

8. Check that replaced wires do not contact sharp edged or pointed

parts.

Fig.5

9. When a power cord has been replaced, check that 10-15 kg of

force in any direction will not loosen it.

(4) As shown in Fig.6, use the crimping tool to crimp the metal

sleeve at the center position. Be sure to crimp fully to the

complete closure of the tool.

Power cord

Crimping tool

Fig.6

Fig.2

(5) Check the four points noted in Fig.7.

10. Also check areas surrounding repaired locations.

Crimped at approx. center

Not easily pulled free

11. Products using cathode ray tubes (CRTs)

of metal sleeve

In regard to such products, the cathode ray tubes themselves, the

high voltage circuits, and related circuits are specified for compli-

ance with recognized codes pertaining to X-ray emission.

Consequently, when servicing these products, replace the cath-

ode ray tubes and other parts with only the specified parts. Under

no circumstances attempt to modify these circuits.

Conductors extended

Wire insulation recessed

more than 4 mm

Unauthorized modification can increase the high voltage value and

cause X-ray emission from the cathode ray tube.

Safety Check after Servicing

•

Examine the area surrounding the repaired location for damage or deterioration. Observe that screws, parts and wires have been returned

to original positions, Afterwards, perform the following tests and confirm the specified values in order to verify compliance with safety

standards.

1. Insulation resistance test

Confirm the specified insulation resistance or greater between power cord plug prongs and exter-

nally exposed parts of the set (RF terminals, antenna terminals, video and audio input and output

terminals, microphone jacks, earphone jacks, etc.). See table 1 below.

2. Dielectric strength test

Confirm specified dielectric strength or greater between power cord plug prongs and exposed acces-

sible parts of the set (RF terminals, antenna terminals, video and audio input and output terminals,

microphone jacks, earphone jacks, etc.). See table 1 below.

3. Clearance distance

When replacing primary circuit components, confirm specified clearance distance (d), (d’) be-

tween soldered terminals, and between terminals and surrounding metallic parts. See table 1

below.

Fig. 8

4. Leakage current test

Confirm specified or lower leakage current between earth ground/power cord plug prongs and

externally exposed accessible parts (RF terminals, antenna terminals, video and audio input and

output terminals, microphone jacks, earphone jacks, etc.).

Measuring Method : (Power ON)

Externally

Insert load Z between earth ground/power cord plug prongs and externally exposed accessible

parts. Use an AC voltmeter to measure across both terminals of load Z. See figure 9 and following

table 2.

exposed

accessible part

Fig. 9

5. Grounding (Class 1 model only)

Confirm specified or lower grounding impedance between earth pin in AC inlet and externally exposed accessible parts (Video in, Video out,

Audio in, Audio out or Fixing screw etc.).

Measuring Method:

Connect milli ohm meter between earth pin in AC inlet and exposed accessible parts. See figure 10 and grounding specifications.

1.1 BEFORE ASSEMBLY AND DISASSEMBLY

1.1.1 Precautions

1.1.4 Disconnection of Connectors (Wires)

Connector

Pull both ends of the connector in the arrow direction, re-

move the lock and disconnect the flat wire.

1. Be sure to remove the power supply unit prior to mount-

ing and soldering of parts.

2. When removing a component part that needs to discon-

nect the connector and to remove the screw for remov-

ing itself, first disconnect the connecting wire from the

connector and then remove the screw beforehand.

Flat wire

3. When connecting and disconnecting the connectors, be

careful not to damage the wire.

4. Carefully remove and handle the part to which some

spacer or shield is attached for reinforcement or insula-

tion.

Connector

5. When replacing chip parts (especially IC parts), desolder

completely first (to prevent peeling of the pattern).

Fig. 1-1-1 Connector 1

6. Tighten screws properly during the procedures.

Unless specified otherwise, tighten screws at a torque

Extend the locks in the direction of the arrow for unlocking

and then pull out the wire. After removing the wire, immedi-

ately restore the locks to their original positions because

the locks are apt to come off the connector.

1.6 DISASSEMBLY/ASSEMBLY OF 0 OP BLOCK

1.6.3 How to assemble CCD base assembly and CCD

board assembly

ASSEMBLY/CCD BOARD ASSEMBLY

1. Install the optical LPF with the spacer rubber attached

to its CCD side in the OP block assembly.

1.6.1 Precautions

1. Take care in handling the CCD image sensor, optical LPF

and lens components when performing maintenance

etc., especially with regard to surface contamination, at-

tached dust or scratching. If fingerprints are present on

the surface they should be wiped away using either a

silicon paper, clean chamois or the cleaning cloth.

Note c: Pay careful attention to the orientation of the LPF.

2. Set the CCD base assembly with careful attention to the

spacer rubber not to come off the right position, and fas-

ten them together with the two screws (1, 2).

3. Set the CCD board assembly in the CCD base assem-

2. The CCD image sensor may have been shipped with a

protective sheet attached to the transmitting glass. When

replacing the CCD image sensor, do not peel off this

sheet from the new part until immediately before it is

mounted in the OP Block Assembly.

bly, and then solder it by the 14 points (SD0).

1.6.4 Replacement of service repair parts

The service repair parts for the OP Block Assembly are as

listed below.

3. The orientation of the optical LPF is an important factor

for installation. If there is some marking on the LPF, be

sure to note it down before removing and to reassem-

ble it very carefully as it was referring to the marking.

Before replacement of these parts, remove the bracket (OP

assembly) as required.

Take special care not to disconnect any of the FPC wires or

cause any damage due to soldering (excessive heating).

1.6.2 How to remove CCD board assembly and CCD

base assembly

1. Focusing motor

2. Zoom motor

1. Unsolder the CCD board assembly by the 14 points

(SD0) and then remove it.

3. Iris motor unit

2. Remove the two screws (1, 2) and remove the CCD base

assembly.

Note d: When replacing the focusing motor or the zoom

above the terminal pin.

heed to the CCD image sensor because the

spacer rubber and optical LPF are occasionally

removed together with the CCD image sensor.

Note e: The iris motor unit includes the FPC Assembly and

two sensors.

Note b: When replacing the CCD image sensor, don’t re-

place it individually but replace the CCD base as-

sembly in whole with a new one.

Details

Possible cause

In the case the encoder position is not shifted

to the next point though the loading motor has

rotated in the loading direction for 4 seconds

or more. This error is defined as [E01].

1. The mechanism is locked during mode shift.

2. The mechanism is locked at the mechanism loading

end, because the encoder position is skipped during

mechanism mode shift.

3. No power is supplied to the loading MDA.

In the case the encoder position is not shifted

to the next point though the loading motor has

rotated in the unloading direction for 4 seconds

or more. This error is defined as [E02].

1. The mechanism is locked during mode shift.

2. The mechanism is locked at the mechanism loading

end, because the encoder position is skipped during

mechanism mode shift.

E03

UNLOADING

In the case no REEL FG is produced for 4 sec-

onds or more in the capstan rotation mode af-

ter loading was complete, the mechanism mode

is shifted to STOP with the pinch roller set off.

This error is defined as [E03].

1. The idler gear does not engage with the reel disk well.

2. Though the idler gear and reel disk are engaged with

each other, the tape is not wound because of over-

load to the mechanism.

3. No FG pulse is output from the reel sensor.

4. No power is supplied to the reel sensor.

5. Tape transport operation takes place with a cassette

having no tape inside.

drum rotation mode for 4 seconds or more.This

error is defined as [E04], and the mechanism

mode is shifted to STOP with the pinch roller

set off.

1. The drum cannot be started or drum rotation is stopped

because tape transport load is too high.

1) Tape tension is extremely high.

2) The tape is damaged or soiled with grease, etc.

2. The DRUM FG signal is not received by the syscon

CPU.

2.5 CHECKUP AND ADJUSTMENT OF MECHANISM PHASE

<Connect gear> (Note 2)

Set the connect gear so

that its locating hole meets

the hole on the main deck

assembly.

Set the “I” of the rotary

part at the tapped hole

as shown in the figure.

<Worm wheel> (Note 2)

Set the worm wheel so

that its locating hole

meets the hole on the

main deck assembly.

Set the sub cam gear

so that its locating hole

meets the hole on the

main deck assembly.

This state represents

that the mechanism is

in the EJECT mode,

which is the “mechanism

assembly mode”.

Note 1

<Main cam gear

/Brake control plate>

After fitting the main cam

gear and brake control plate

together,set them together

so that their locating holes

meet the hole on the main

deck assembly.

<Connect gear 2> (Note 2)

Set the connect gear 2 so

that its locating hole meets

the hole on the main deck

assembly.

Note 1:

Note 2:

Since the connect gear 2 is tightly fixed to the main deck

by caulking, adjust its phase with the connect gear and

sub cam gear.

The part that needs phase adjustment by the hole on the main

deck assembly must exactly be set as the specified phase.

There is a fear that some part is installed in a wrong phase

because assembling of the mechanism is automated. If so,

set every part in the correct phase whenever the mechanism

is reassembled.
