SECTION 1

PRECAUTIONS

1.1 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.

1.1.1 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.

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.

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. Consequently, 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 connectorIn 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).

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.

Fig.1-1-4

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

Insert the wires fully into the connector.

Fig.1-1-5

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.

Fig.1-1-6

e) Check the four points noted in Fig.1-1-7.

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.

Fig.1-1-8

(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)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.

Fig.1-1-9

(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 Fig.1-1-10 and grounding

specifications.

3.1 BEFORE ASSEMBLY AND DISASSEMBLY

3.1.1 Precautions

• Be sure to disconnect the power supply unit prior to mounting

and soldering of parts.

• 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).

• When connecting/disconnecting wires, pay enough attention

not to damage the connectors.

• When inserting the flat wire to the connector, pay attention to

the direction of the flat wire.

• Be careful in removing the parts to which some spacer or

shield is attached for reinforcement or insulation.

• When replacing chip parts (especially IC parts), first remove

the solder completely to prevent peeling of the pattern.

• Tighten screws properly during the procedures. Unless

otherwise specified, tighten screws at a torque of 0.088N·m
