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 Tape3) Spacers5) Barrier
2) PVC tubing4) 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.

Pay the most careful attention to the transparent glass and
optical LPF of the CCD image sensor so a not the soil and
damage them. If something is soiled with finger-prints, etc.,
gently clean it with silicon-processed paper/cloth or chamois.
•
When the CCD image sensor is shipped from the factory,
there are protection seals applied onto the transparent
glass. Leave the protector as it is, and take it off just before assembling the CCD image sensor to the OP block.
1.5.1 Removal of CCD image sensor
1. Remove two screws (S1a) securing the CCD base assy,
and disassemble the CCD spacer, the optical LPF,
spacer rubber.
1.5.2 Installation of new CCD image sensor
1. Remove the protection seal from a new CCD image sen-
sor. Next, put the optical LPF, spacer rubber, CCD
spacer on the CCD image sensor as they are piled up
in this order. At that time, make sure of orientation of each
item refering to the following table (see Fig. 1-5-1).
Part NameOrientation
CCD image sensorMark is on the right viewed as indi-
cated by the arrow a .
Spacer rubberIC side is horizontal.
Optical LPFMarks are on the left and bottom
viewed as indicated by the arrow
a .
2. Fix the CCD base assembly to OP block with the two
screws (S1a) . At that time, be careful of the orientation.
3. After completion of all P.C. boards to the camera section, observe the monitor to confirm no vignetting caused
by the bodytube, rings, lens hood, etc. If no vignetting
is observed, it can be said that image's parallel,
horizontality and centering are correct.
1.5.3 Replacement of CCD board assembly
1. Remove one screw (S1b).
2. Unsolder at the fourteen points on the CCD board assembly.
Notes:
•
Remove the screw (S1b) only when the CCD board assembly needs replacement.
•
When installing a new CCD board assembly, carry out the
above-mentioned procedure in the reverse order.

1.6 TAKE OUT CASSETTE TAPE
In the event that the set enters the emergency mode as it
is loaded with a cassette tape and the cassette tape cannot be ejected with the EJECT button, manually, take it out
of the set according to the following procedure.
Note:
If the mechanism comes into the unloading mode as the
•
cassette tape is not held by hand, it results in tape damage.
1. Disconnect the set from the power source.
2. Remove the cassette cover assembly, Upper case,
Lower case assembly, Top operation unit, Front cover
assembly (See Fig. C1, C2, C3, C5 and C7, Pages 1-4
to 1-6).
3. Connect a jumper wire to each pole of the loading motor as shown by the magnified view (Fig. 1-6-1)
4. While holding down the cassette housing by hand, connect the jumper wires to a battery to run the mechanism
to the EJECT position four unloading. If this unloading
operation is performed as the cassette housing is not
held down by hand, the front lid of the cassette may
damage the tape when it is ejected.
5. For taking in the slack of the tape, run the mechanism
to the EJECT position as the front lid of the cassette is
left open, and turn the take-up gear in the forward direction to wind up the tape. After confirming that the tape
has completely been wound up and the supply reel is
idling, take the cassette tape out of the cassette housing.

2.5 REMARKS
2.5.1 Cleaning
1. For cleaning of the upper drum (particularly video
heads), use fine-woven cotton cloth or Kimwipe with alcohol soaks through. Do not move the cloth but turn the
upper drum counterclockwise.
Note:
Make sure not to move the cloth in the vertical direction to the video head, since it may cause damage of the video heads.
2. For cleaning of parts of the tape transport system except the upper drum, use fine-woven cotton cloth or cotton swab soaked alcohol.
3. After cleaning, confirm that the cleaned parts are completely dry before loading the deck with cassette tape.
2.5.2 Applying oil and grease
1. Periodical oiling and greasing are not required but should
be done to new parts when replacing. If oil and grease
on the other parts of the other party are old and dirty,
wipe them clean and apply new oil or grease.
2. For parts and points to apply oil and grease, refer to the
exploded view of the mechanism assembly (M3).
Table 2-5-1 specifies oil and grease to be used.
3. When oiling, clean the objective parts with alcohol first
and apply one or two drop(s) of oil. Too much oiling
causes rotary parts to slip because of oil leakage.
