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).

1.6 DISASSEMBLY/ASSEMBLY OF 5OP BLOCK
ASSEMBLY/CCD BOARD ASSEMBLY
1.6.1 Precautions
1. Take care in handling the CCD image sensor, optical LPF
and lens components when performing maintenance
etc., especially with regard to surface contamination, at-
tached 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 Assembly.
3. The orientation of the optical LPF is an important factor
for installation. If there is some marking on the LPF, be
sure to note it down before removing and to reassem-
ble it very carefully as it was referring to the marking.
1.6.2 How to remove CCD board assembly and CCD
base assembly
1. Unsolder the CCD board assembly by the 14 points
(SD5) and then remove it.
2. Remove the two screws (1, 2) and remove the CCD base
assembly.
Note 5a:
When removing the CCD base assembly, pay
heed to the CCD image sensor because the
spacer rubber and optical LPF are occasionally
removed together with the CCD image sensor.
Note 5b: When replacing the CCD image sensor, don’t re-
place it individually but replace the CCD base as-
sembly in whole with a new one.
1.6.3 How to assemble CCD base assembly and CCD
board assembly
1. Install the optical LPF with the spacer rubber attached
to its CCD side in the OP block assembly.
Note 5c:
Pay careful attention to the orientation of the LPF.
2. Set the CCD base assembly with careful attention to the
spacer rubber not to come off the right position, and fas-
ten them together with the two screws (1, 2).
3. Set the CCD board assembly in the CCD base assem-
bly, and then solder it by the 14 points (SD5).
1.6.4 Replacement of Service Repair Parts
The service repair parts for the OP Block Assembly are as
listed below.
Before replacement of these parts, remove the bracket (OP
assembly) as required.
Take special care not to disconnect any of the FPC wires or
cause any damage due to soldering (excessive heating).
1. Focusing motor
2. Zoom motor
3. Iris motor unit
Note 5d:
When replacing the focusing motor or the zoom
motor, solder the FPC at a space of about 1 mm
above the terminal pin.
Note 5e: The iris motor unit includes the FPC Assembly and
two sensors.
