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
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.
symbol and shaded ( ) parts are
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.

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.
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. Carefully handle the CCD image sensor, optical 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 assembly.
1.6.2 How to remove OP block assembly and CCD board
assembly
1. Unsolder at the two points (SD1) and remove the shield
case.
2. Unsolder at the sixteen points (SD2) and remove the CCD

When replacing the CCD image sensor, don’t
replace it individually but replace the CCD base
assembly in whole with a new one.
1.6.3 How to install OP block assembly and CCD board
assembly
1. Install the optical LPF with the space rubber fitted to its
CCD side in the OP block assembly.
2. Paying heed to the space rubber not to get it to come off
the setting position, install the CCD base assembly in
place and fasten it together with the space rubber with the
two screws (1, 2).
3. Set the CCD board assembly in the CCD base assembly,
and fasten it by soldering at the fourteen points (SD2).

1.7 HOW TO TAKE OUT CASSETTE TAPE MANUALLY
1.7.1 How to remove cassette tape manually from the set
If the cassette tape is not ejected from the cassette housing
because of some electric trouble, it can be removed from the
set by the temporary measure that is to turn the loading motor
forcibly as mentioned below.
Through the removing work, pay heed to the exterior parts
such as the covers, etc. as well as to the cassette tape to get
nothing damaged.
<Procedure>
1. Disconnect the power supply (battery or DC cord) from
the set.
2. Dismantle the deck ope assy, front cover assembly
referring to the section 1 (page 1-4, 1-5).
Note:
When and after dismantling the front assembly, pay
careful attention to the internal components such as
the OP block assembly (lens), battery terminal, etc.
that are exposed after the front assembly is removed.
3. Open the cassette cover assembly completely and hold
it open through the work.
4. Supply 3 V DC to the terminals (electrodes) on the top
of the loading motor to slide the slide deck assembly
to the front side, and stop the power supply when both
the pole bases are positioned in the unloading status
inside the tape. Since the tape remains as it is not
wound up at that time, pay careful attention to the tape
not to damage it and not to soil it with grease, etc. If
unloading operation is continued after both the pole
bases return to their respective positions inside the tape,
the mechanism enters the eject mode and the cassette
housing assembly is lifted up. If it occures, the pulledout tape may be caught in the cassette lid and the tape
may be resultingly damaged.
5. Turn the center gear assembly with a sharp-pointed thing
(chip IC replacing jig, etc.) in the direction of the arrow
to wind up the tape. Carefully turn the center gear assembly not to damage the tape.
If the tape cannot be wound up by turning the center gear
assembly, it is thinkable that the idler arm assembly is
positioned not to engage with the reel disk assembly. If
so, shift the mechanism mode so that the idler arm
assembly is correctly engaged with the reel disk assembly. After fine adjusting the engagement, try to wond up
the tape is the same manner once more.
In such the event, it is recommended to shift the idler
arm assembly slightly in the loading direction.
6. After confirming that the tape is completely wound up,
proceed with unloading operation until the mechanism
enters the eject mode. Then, take the cassette tape out
of the cassette housing.
7. After removing the cassette tape, check to see if the
manually wound part of the tape is not soiled with grease,
etc. At the same time, check the mechanism assembly,
particularly the tape transport system, whether there is
something abnormal or not.
Whenever some abnormal signal is input to the syscon CPU,
an error number (E01, as an example) is displayed on the
LCD monitor or (in the electronic view finder).
In every error status, such the message as shown below
alternately appear over and over.
•In an emergency mode, all operations except turning on/
off the POWER switch are ineffectual.

ASSEMBLY
2.2.1General statement
The mechanism should generally be disassembled/assembled in the EJECT mode (ASSEMBLY mode). (Refer to Fig.
2-2-1.)
However, when the mechanism is removed from the main body,
it is set in the STOP mode. Therefore, after the mechanism is
removed from the main body, supply 3 V DC to the electrode
on the top of the loading motor to enter the mechanism mode
into the EJECT mode compulsory.

<REV mode>
2.2.2Explanation of mechanism mode
The mechanism mode of this model is classified into six
modes as shown in Table 2-2-1. Each mechanism mode can
be distinguished from others by the relative position of “Q”
mark on the sub cam gear to the inner or outer protrusion
on the main deck.
Refer to Fig. 2-2-2 to 2-2-7 below.
The EJECT mode, C IN mode and SHORT FF mode should
be recognized by the relative position of the “Q” mark to
the inner protrusion, while the STOP mode, REV mode and
PLAY mode should be recognized by that to the outer protrusion.
Shift the mechanism mode
from the STOP mode to the
EJECT mode.
Note 1b:
Reassemble the cassette
housing assembly to the
mechanism as the cancel lever
is moved in the direction of the
arrow.
Note 1c:
When reassembling the cassette housing to the mechanism, make sure that there is
no deformation in the frame or
no damage to the switches,
etc.
Note 1d:
After reassembling the component parts, check the mechanism operation in the PLAY
mode.
For details of checking method,
refer to “2.2.8 assembling slide

that its locating hole
meets the hole on the
main deck assembly.
<Main cam gear
/Brake control plate>
After fitting the main cam\
gear and brake control plat
together,set them together
so that their locating holes
meet the hole on the main \
deck assembly.
<Connect gear> (Note 2)
Set the connect gear so
that its locating hole meets
the hole on the main deck
assembly.
Note 1
<Connect gear 2> (Note 2)
Set the connect gear 2 so
that its locating hole meets
the hole on the main deck
assembly.
<Sub cam gear>
Set the sub cam gear
so that its locating hole
meets the hole on the
main deck assembly.
This state represents
that the mechanism is
in the EJECT mode,
which is the “mechanism
assembly mode”.
Note 1:
Since the connect gear 2 is tightly fixed to the main deck
by caulking, adjust its phase with the connect gear and
sub cam gear.
Fig. 2-2-24
Note 2:
The part that needs phase adjustment by the hole on the main
deck assembly must exactly be set as the specified phase.
There is a fear that some part is installed in a wrong phase
because assembling of the mechanism is automated. If so,
set every part in the correct phase whenever the mechanism
is reassembled.
