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.

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).

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

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

DISASSEMBLY

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

·cm). However, as this is a required value at the time of

(0.9kgf

zPrecautions

(1) Be careful in handling the CCD IMAGE SENSOR, OPTI-

CAL LPF and the LENS components. Pay special atten-

tion not to soil or damage the surfaces., especially with

regard to surface contamination, attached 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.
(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 ASSY.

from scratches or damages, leave the CUSHION as

long as it does not interfere with the procedure.

zDisassembly of OP BLOCK ASSEMBLY / CCD BOARD AS-

SEMBLY

(1) Unsolder the fourteen soldered points (SD11a) of the

CCD BOARD ASSY.
(2) Remove the two screws (1,2), and then remove the CCD

BOARD ASSY and the CCD BASE ASSY.

NOTE11a:

When removing the CCD BASE ASSY, be careful in
handling as the CCD IMAGE SENSOR may be re­moved together with the SHEET and the OP LPF at­tached.

NOTE11\b:

Replace the CCD IMAGE SENSOR as a CCD BASE
ASSY, not as a single part replacement.

zAssembly of OP BLOCK ASSEMBLY / CCD BOARD AS-

SEMBLY

(1) Set the OPTICAL LPF first, and then the SHEET to the

OP BLOCK ASSY.

NOTE11c:

Be careful with the attachment direction of the OP
LPF.

(2) Attach the CCD BASE ASSY first, then the CCD BASE

ASSY so that the SHEET stays in place, and then tighten
with the two screws (1, 2).
