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.
Fig.1
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.
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.
Power cord
Fig.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 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.
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 connec-
tors, if replacing the connectors is unavoidable, in order 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
cut close to connector
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.
15 mm
Fig.4
(3) Align the lengths of the wires to be connected. Insert the
wires fully into the connector.

Metal sleeve
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.

•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.
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 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.

move the lock and disconnect the flat wire.
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 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.
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.
5. When replacing chip parts (especially IC parts), desolder
completely first (to prevent peeling of the pattern).

1. Carefully handle the CCD image sensor, optical LPF,
lens, etc. during the disassembly work. Pay the most
careful attention to the surface of those parts not to get
it soiled, scratched or dusty. If some of those surfaces
gets soiled with fingerprints, etc., wipe it out with silicone
paper, clean chamois, cleaning cloth or the like.
2. The new CCD image sensor is occasionally shipped from
the factory as a protection seal is applied onto its trans-
parent glass. If so, leave the protection seal as it is and
remove it just before installing the CCD image sensor in
the OP block assembly.
1.5.2 How to remove @OP block assembly and CCD
board assembly
1. Unsolder at the fourteen points (SD@) and remove the
CCD board assembly.
2. Remove the two screws (1, 2) and then remove the CCD
base assembly.
Note@a:
Carefully remove the CCD base assembly, be-
cause the space rubber and optical LPF may be
removed together with the CCD image sensor.

place it individually but replace the CCD base as-
sembly in whole with a new one.
1.5.3 How to install @OP block assembly and CCD
board assembly
1. Install the optical LPF with the @OP block assembly.
2. With the spacer rubber left attached to the CCD base
assembly, install the assembly in the OP block assem-
bly and clamp it using the two screws (1, 2).
3. Set the CCD board assembly in the CCD base assem-
bly, and fasten it by soldering at the fourteen points
(SD@).
1.5.4 Replacement of service parts

1.8 SERVICE KNOW-HOW
When performing disassembly/assembly work to this model,
the parts that are most complicated and require special at-
tention are the E. VF unit and the OP MDA board, OP block
and shoe assemblies, all of which are mounted inside the
lower case assembly.
Care should be taken in handling these parts as they are
mounted inside the lower case assembly (except the E.VF
unit) and there is a lack of adequate space to work conven-
iently. This section gives further details regarding the disas-
sembly procedures, although they have been described in
previous sections.
1. See Fig. 1-8-1.
(1) While moving the !microphone out of way, remove the
screw (39) and take out the @OP block assembly.
(2) Remove two screws (40, 41) and open the $OP MDA
board assembly.
(3) Remove two screws (42, 43) to disconnect the connec-
tor (CN203), then take out the FPC to remove the #E.
VF unit.
Note #a :
Be careful not to damage the FPC or the switches
when carrying out this work.
