Important Safety Precautions
Connector
Metal sleeve
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.
v
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.
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.

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.

1.6 DISASSEMBLY/ASSEMBLY OF @ OP BLOCK ASSY
(CCD BOARD ASSY)
1.6.1 Precautions
1. Carefully handle the CCD IMAGE SENSOR, OP 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
transparent glass. If so, leave the protection seal as it is
and remove it just before installing the CCD IMAGE SENSOR in the OP BLOCK ASSY.
3. The orientation of the OP LPF is an important factor for
installation. If there some marking on the OP LPF, be sure
to note it down before removing and to reassemble it very
carefully as it was referring to the marking.
1.6.2 Disassembly method
1. Unsolder at the 14 points (SD@) and remove the CCD
BOARD ASSY.
2. Remove the two screws (1, 2) and then remove the CCD
BASE ASSY.
NOTE
a:
Carefully remove the CCD BASE ASSY, because
@
the SPACE RUBBER and OP LPF may be removed together with the CCD IMAGE SENSOR.
NOTE@b:
1.6.3 Assembly method
1. Install the OP LPF with the @ OP BLOCK ASSY.
2. With the SPACER RUBBER left attached to the CCD
3. Set the CCD BOARD ASSY in the CCD BASE ASSY, and
1.6.4 Replacement of service parts
Service parts to be supplied for the OP BLOCK ASSY are
as follows.
When replacing a part, be very careful not to get the FPC
wire broken or damaged by soldering (overheating).
1. FOCUS MOTOR
2. ZOOM MOTOR
3. IRIS MOTOR UNIT
NOTE
NOTE@d:
When replacing the CCD IMAGE SENSOR, don’t
replace it individually but replace the CCD BASE
ASSY in whole with a new one.
BASE ASSY, install the assembly in the OP BLOCK ASSY
and clamp it using the two screws (1, 2).
fasten it by soldering at the 14 points (SD@).
c:
When soldering the FPC wire of the FOCUS MO-
@
TOR or ZOOM MOTOR during the replacement
work, be sure to keep the tip of a soldering iron
approximately 1 mm above the terminal.
