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.

1. Locations requiring special caution are denoted by labels and

inscriptions on the cabinet, chassis and certain parts of the

product. When performing service, be sure to read and com-

ply with these and other cautionary notices appearing in the

operation and service manuals.

2. Parts identified by the

symbol and shaded (

) parts are

critical for safety.

Replace only with specified part numbers.

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.

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

3) High voltage leads

5. Use specified insulating materials for hazardous live parts.

Note especially:

1) Insulation Tape

3) Spacers

5) Barrier

2) PVC tubing

4) Insulation sheets for transistors

6. When replacing AC primary side components (transformers,

power cords, noise blocking capacitors, etc.) wrap ends of

wires securely about the terminals before soldering.

10. Also check areas surrounding repaired locations.

11. Products using cathode ray tubes (CRTs)

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

the high voltage circuits, and related circuits are specified for

compliance 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.

Unauthorized modification can increase the high voltage value

and cause X-ray emission from the cathode ray tube.

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

transformer primary lead wires are performed using crimp type

connectors, if replacing the connectors is unavoidable, in or-

der to prevent safety hazards, perform carefully and precisely

according to the following steps.

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.

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

Fig.7

Fig.3

(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.

Fig.4

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

the wires fully into the connector.

Fig.5

(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.

Precautions during Servicing

7. Observe that wires do not contact heat producing parts

(heatsinks, oxide metal film resistors, fusible resistors, etc.)

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

pointed parts.

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

force in any direction will not loosen it.

Fig.6

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

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 compli-

ance with safety standards.

1. Insulation resistance test

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

externally 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

accessible 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.

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)

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

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

following table 2.

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.

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.

DISASSEMBLY

1.1 BEFORE ASSEMBLY AND DISASSEMBLY

1.1.1 Precautions

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 disconnect

the connector and to remove the screw for removing itself,

first disconnect the connecting wire from the connector and

then remove the screw beforehand.

3. When connecting and disconnecting the connectors, be

careful not to damage the wire.

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

completely first (to prevent peeling of the pattern).

5. Tighten screws properly during the procedures.

Unless specified otherwise, tighten screws at a torque

of 0.098N·m (1.0kgf·cm).
