PRECAUTIONS
1.1 SAFTY 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.
1.1.1 Precautions during Servicing
(1) Locations requiring special cauti on 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
comply 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:
• Wires covered with PVC tubing
• Double insulated wires
• High voltage leads
(5) Use specified insulating materials for hazardous live parts.
Note especially:
• Insulation Tape
• PVC tubing
•Spacers
• Insulation sheets for transistors
•Barrier
(6) When replacing AC primary side compon ents (transformers,
power cords, noise blocking capacitors, etc.) wrap ends of
wires securely about the terminals before soldering.
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.
(12) Crimp type wire connectorIn 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 connectors, if
replacing the connectors is unavoidable, in order to prevent
safety hazards, perform carefully and precisely according
to the following steps.
• Connector part number :E03830-001
• Required tool : Connector crimping tool of the proper
type which will not damage insulated parts.
• Replacement procedure
a) 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.1-1-3
b) Strip about 15 mm of the insulati on from the ends
of the wires. If the wires are stranded, twist the
strands to avoid frayed conductors.
15 mm
Fig.1-1-4
c) Align the lengths of the wires to be connected.
Insert the wires fully into the connector.
Metal sleeve
Fig.1-1-1
(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.1-1-2
(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

1.1.2 Safety Check after Servicing
Examine the area surrounding the repaired location for d amage
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 Fig.1-1-11 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 Fig.1-1-11 below.

DISASSEMBLY
3.1 BEFORE ASSEMBLY AND DISASSEMBLY
3.1.1 Precautions
• Be sure to disconnect the power supply unit prior to mounting
and soldering of parts.
• Prior to removing a component part that needs to disconnect
its connector(s) and its screw(s), first disconnect the wire(s)
from the connector(s), and then remove the screw(s).
• When connecting/disconnecting wires, pay enough attention
not to damage the connectors.
• When inserting the flat wire to the connector, pay attention to
the direction of the flat wire.
• Be careful in removing the parts to which some spacer or
shield is attached for reinforcement or insulation.
• When replacing chip parts (especially IC parts), first remove
the solder completely to prevent peeling of the pattern.
• Tighten screws properly during the procedures. Unless
specified otherwise, tighten screws at a torque of 0.118N
·cm). However, 0.118N·m (1.2kgf·cm) is a value at the
(1.2kgf
time of production. At the time of service, perform the
procedure at a torque 10% less than 0.118N
·m (1.2kgf·cm).
(See "SERVICE NOTE" as for tightening torque.)

BOARD ASSEMBLY together with CCD BASE ASSEMBLY.
(2) Remove the LPF HOLDER from the CCD BASE AS-
SEMBLY, and remove the MASK.
NOTE 12a:
Since the MASK is between the LPF HOLDER and
CCD IMAGE SENSOR, be careful in handling the
MASK.
NOTE12b:
In removing the CCD IMAGE SENSOR, unsolder the
fourteen soldered parts (SD12a), and remove the
CCD BASE ASSEMBLY from the CCD BOARD ASSEMBLY.
In replacing the CCD IMAGE SENSOR, don't remove
the CCD IMAGE SENSOR from the CCD BASE ASSEMBLY. Instead, replace the whole CCD BASE ASSEMBLY.

NOTE12c:
Since the OP LPF is inside the LPF HOLDER and the
OP LPF is attached to the LPF HOLDER by using the
SHEET, remove the OP LPF from the LPF HOLDER if
necessary.
In removing the OP LPF from the LPF HOLDER, be
careful not to damage the LPF HOLDER, and remove
the SHEET carefully if you want to use the same
SHEET in attachment procedure.
NOTE12d:
In removing the OP LPF, be careful of the direction of
its attachment. Since one side of the OP LPF is coated
for the purpose of protection, attach the OP LPF so
that the coated side faces the OP lens (a subject of

5.2 TAKE OUT CASSETTE TAPE
The following procedure is a method for taking out the cassette
tape in case the cassette tape cannot be ejected due to an electrical failure. The following procedure is a simplified method;
therefore, for more reliable operation, it is recommended that you
should remove exterior parts so that you can take out the tape
without excessive force.
(1) Remove the Power Unit (battery or DC cord) from the set.
(2) Open the CASSETTE COVER till it is completely opened
and fixed.
(3) Attach a PVC tape as shown in the figure.
NOTE:
Be careful of cassette tape damage caused because the
Cassette Housing Assembly is moved upward at the unloading end (Eject mode).
(4) To set the Slide Deck Assembly to the un loading end , ap-
ply DC 3V to the electrode (terminal) on the top surface of
the LOADING MOTOR that is seen through a space of VF
side.
NOTE:
Be careful not to attach grease or a similar substance to
the surface of the cassette tape on the tape transport
system.
(5) Wind the cassette tape by directly turning the Reel Disk As-
sembly (SUP) from the backside of the SLIDE DECK ASSEMBLY by using a sharp tool (Chip IC replacement tool).
(6) Confirm that the cassette tape is completely woun d, and
then peel off the PVC tape from the CASSETTE HOUSING
ASSEMBLY and take out the cassette tape.
NOTE:
To confirm that the cassette tape is completely wound,
confirm that one REEL DISK ASSEMBLY (TU) rotates
as you rotate the other REEL DISK ASSEMBLY (SUP).
(7) Make sure that grease or a similar substance is not at-
tached to the surface of the tape taken out in the procedure
(6). Similarly, also make sure that grease or a similar substance is not attached on the MECHANISM ASSEMBLY,
especially the tape transport system.
