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.

(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).

1.4.1 Precautions
1. Take care in handling the CCD image sensor, optical LPF
and lens components2when 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 rec-
ommended by the Video Product Division.
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.

1. Remove the solder (SD1) from the 16 soldered points
on the CCD Board Assembly and take the assembly out.
2. Remove the two screws (1, 2) and take out the CCD Base
Assembly.
Note 4a:
When removing the CCD Base Assembly, be
careful not to take out the CCD image sensor to-
gether with the spacer rubbers attached to it.
Note 4b: The CCD image sensor should not be replaced
as a single part but should be replaced together
with the entire CCD Base Assembly.
1.4.3 How to install
1. With the spacer rubbers attached to the CCD base,
mount the CCD base in the OP Block Assembly and
tighten them together using the two screws (1, 2).
2. Mount the CCD Board Assembly and attach solder to
the 16 points (SD1).
1.4.4 Replacement of Service Repair Parts
The service repair parts for the OP Block Assembly are as
listed below.

1.7 MANUAL EJECTION OF THE CASSETTE TAPE
Note:
The following procedure describes a simplified method
of ejecting the cassette tape in case it is not possible
to eject it, due to an electrical failure.
Be careful not to damage any of the parts or the tape
when performing repairs or maintenance work.
1. Remove the Power Unit (battery, DC code, etc.) from the
main unit.
2. Open the cassette cover.
3. Attach a piece of PVC tape at the front of the cassette
housing.
Note:
This helps prevent the tape from being damaged when
the Cassette Housing Assembly is moved upward at
the unloading end.
4. In order to change the mechanism mode at the unload-
ing end apply 3 V, DC to the electrode on the top sur-
face of the Loading Motor Assembly and then set it to
the eject mode.
5. If there is any slack tape in the tape transport system,
wind it inside the cassette tape by turning the Supply
Reel Disk from the backside of the Slide Deck Assem-
bly.
6. Peel off the PVC tape and take out the cassette tape from
the cassette housing.
Note:
Make sure that grease or a similar substance is not
attached to the surface of the tape.
Similarly, also make sure that grease or a similar sub-
stance is not attached on the Mechanism
Assembly.

1.8 EMERGENCY DISPLAY
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.

Emergency
mode Details Possible cause
E01 LOADING In the case the encoder position is not shifted
to the next point though the loading motor has
rotated in the loading direction for 4 seconds
or more. This error is defined as [E01].
1. The mechanism is locked during mode shift.
2. The mechanism is locked at the mechanism load-
ing end, because the encoder position is skipped
during mechanism mode shift.
3. No power is supplied to the loading MDA.
E02 UNLOADING In the case the encoder position is not shifted
to the next point though the loading motor has
rotated in the unloading direction for 4 sec-
onds or more. This error is defined as [E02].
1. The mechanism is locked during mode shift.
2. The mechanism is locked at the mechanism load-
ing end, because the encoder position is skipped
during mechanism mode shift.
E03 TU & SUP REEL
FG
In the case no REEL FG is produced for 4 sec-
onds or more in the capstan rotation mode af-
ter loading was complete, the mechanism
mode is shifted to STOP with the pinch roller
set off.
This error is defined as [E03].
However, no REEL EMG is detected in the
SLOW/STILL mode.
1. The idler gear does not engage with the reel disk
well.
2. Though the idler gear and reel disk are engaged with
each other, the tape is not wound because of over-
load to the mechanism.
3. No FG pulse is output from the reel sensor.
4. No power is supplied to the reel sensor.
5. Tape transport operation takes place with a cassette
having no tape inside.
6. The tape slackens and no pulse is produced until
the slack is taken up and the tape comes into the
normal status.
E04 DRUM FG In the case there is no DRUM FG input in the
drum rotation mode for 4 seconds or more.
This error is defined as [E04], and the mecha-
nism mode is shifted to STOP with the pinch
roller set off.
1. The drum cannot be started or drum rotation is
stopped because tape transport load is too high.
1) Tape tension is extremely high.
2) The tape is damaged or soiled with grease, etc.
2. The DRUM FG signal is not received by the syscon
CPU.
1) Disconnection in the middle of the signal line.
2) Failure of the DRUM FG pulse generator (hall ele-
ment).
3. No drum control voltage is supplied to the MDA.
4. No power is supplied to the DRUM MDA.
E05 –––
E06 CAPSTAN FG In the case no CAPSTAN FG is produced in
the capstan rotation mode for 2 seconds or
more. This error is defined as [E06], and the
mechanism mode is shifted to STOP with the
pinch roller set off.
However, no CAPSTAN EMG is detected in the
STILL/FF/REW mode.
1. The CAPSTAN FG signal is not received by the
syscon CPU.
1) Disconnection in the middle of the signal line.
2) Failure of the CAPSTAN FG pulse generator (MR
element).
2. No capstan control voltage is supplied to the MDA.
3. No power is supplied to the CAPSTAN MDA.
4. The capstan cannot be started or capstan rotation
is stopped because tape transport load is too high.
1) Tape tension is extremely high. (Mechanical

2.3.2 Explanation of mechanism mode
The mechanism mode of this model is classified into five
modes as shown in Table 2-3-1. Each mechanism mode
can be distinguished from others by the relative position
of “”, “Q”, “
Q
”“ ” marks on the sub cam gear to the in-
ner or outer protrusion on the main deck.
Refer to Fig. 2-3-3 to 2-3-8 below.
2.3 DISASSEMBLY/ASSEMBLY OF MECHANISM AS-
SEMBLY
2.3.1 General statement
The mechanism should generally be disassembled/assem-
bled in the C.IN mode (ASSEMBLY mode). (Refer to Fig.
2-3-1,2.)
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 C,IN mode compulsory.
