PRECAUTIONS

1.1 SAFTY 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.

1.1.1 Precautions during Servicing

(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
comply 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
comply 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:

• Wires covered with PVC tubing

• Double insulated wires

• High voltage leads

(5) Use specified insulating materials for hazardous live parts.

Note especially:

• Insulation Tape

• PVC tubing

•Spacers

• Insulation sheets for transistors

• Barrier

(6) When replacing AC primary side components (transformers,

power cords, noise blocking capacitors, etc.) wrap ends of
wires securely about the terminals before soldering.

quently, when servicing these products, replace the cathode
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 trans former primary lead wires are performed using
crimp type connectors, if replacing the connectors is un­avoidable, in order to prevent safety hazards, perform care­fully and precisely according to the following steps.

• Connector part number :E03830-001

• Required tool : Connector crimping tool of the proper
type which will not damage insulated parts.

• Replacement procedure

a) Remove the old connector by cutting the wires at a

point close to the connector.
Important : Do not reuse a connector (discard it).

cut close to connector

Fig.1-1-3

b) 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.

15 mm

Fig.1-1-4

c) Align the lengths of the wires to be connected. Insert

the wires fully into the connector.

Metal sleeve

Fig.1-1-1

(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.

Power cord

Fig.1-1-2
(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. Conse-

d) As shown in Fig.1-1-6, 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.

1.1.2 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 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 Fig.1-1-11 below.

(3) Clearance distance

When replacing primary circuit components, confirm spec­ified clearance distance (d), (d') between soldered termi­nals, and between terminals and surrounding metallic
parts. See Fig.1-1-11 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 accessible parts. Use an
AC voltmeter to measure across both terminals of load Z.
See Fig.1-1-9 and following Fig.1-1-12.

(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 Fig.1-1-10 and grounding
specifications.

SPECIFIC SERVICE INSTRUCTIONS

2.1 BEFORE ASSEMBLY AND DISASSEMBLY

2.1.1 Precautions

1. Be sure to disconnect the power supply unit prior to mount­ing and soldering of parts.

2. Prior to removing a component part that needs to disconnect
its connector(s) and its screw(s), first disconnect the wire(s)
from the connector(s), and then remove the screw(s).

3. When connecting/disconnecting wires, pay enough atten­tion not to damage the connectors.

4. Be careful in removing or handling the part to which some
spacer or shield is attached for reinforcement or insulation.

5. When replacing chip parts (especially IC parts), first remove
the solder completely to prevent peeling of the pattern.

6. Tighten screws properly during the procedures. Unless
specified otherwise, tighten screws at a torque of

0.088N•m (0.9kgf•cm).

2.1.4 Disconnection of connectors (Wires)

Pull both ends of the connector in the arrow direction, remove the
lock and disconnect the flat wire.

Extend the locks in the direction of the arrow for unlocking and
then pull out the wire. After removing the wire, immediately re­store the locks to their original positions because the locks are
apt to come off the connector.
