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.

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 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.

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 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).

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.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.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.

Fig.4

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

wires fully into the connector.

(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.

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 table 1 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 table 1
below.

Fig. 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 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.

SECTION 1

DISASSEMBLY

1.1 BEFORE ASSEMBLY AND DISASSEMBLY

1.1.1 Precautions

1. Be sure to remove the power supply unit prior to mount­ing 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. Carefully remove and handle the part to which some
spacer or shield is attached for reinforcement or insula­tion.

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

6. Tighten screws properly during the procedures.
Unless specified otherwise, tighten screws at a torque
of 0.088N

Note:

The shape of the monitor assembly varies by the size
of the LCD screen.

For the 2.5”-type LCD, refer to Fig. 1-4-1.

3. Unplug the wires and FPCs from the two connectors b ,
c , and then remove the MONITOR BL board assembly,
holder (PWB) and backlight in that order.

4. Remove the LCD module.

1.4.1 Disassembly/assembly of monitor assembly
(for 2.5”-type LCD)

Note:

Be careful not to soil or scratch the monitor screen
through the disassembly/assembly work.

1. Remove the four screws 1 to 4 in numerical order. While

disengaging the six hooks (L4a to L4f) in alphabetical
order, remove the monitor cover assembly.

2. Unlock the connector a and then disconnect the FPC

while lifting the hinge assembly upwards to remove it to­gether with the FPC.

Note

a:

For disconnecting the FPC, unlock the connector

4

first and then lift the hinge assembly upwards.
Accordingly, the FPC is disconnected together
with the hinge assembly.

Note4b:

Treat the wires carefully.

hinge assembly.

Note

c:

When connecting the FPC, arrange the FPC wire

by winding it around the shaft (hinge pin) of the
hinge assembly by two and a half turns while pay­ing heed to the orientation of the hinge assembly
and FPC.

Note4d:

When disassembling/assembling the hinge assem­bly, pay careful attention to every part not to dam­age anything.
