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 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.

(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.

DISASSEMBLY
1.1 BEFORE ASSEMBLY AND DISASSEMBLY
1.1.1 Precautions
1. Be sure to remove the power supply unit prior to mounting and soldering of parts.
2. When removing a component part that needs to disconnect the connector and to remove the screw for removing 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 insulation.
5. When replacing chip parts (especially IC parts), desolder
completely first (to prevent peeling of the pattern).
6. Tighten screws properly during the procedures.
Unless specified otherwise, tighten screws at a torque
of 0.088N

1.6 DISASSEMBLY/ASSEMBLY OF 0 OP BLOCK
ASSEMBLY/CCD BOARD ASSEMBLY
1.6.1 Precautions
1. Take care in handling the CCD image sensor, optical LPF
and lens components when performing maintenance
etc., especially with regard to surface contamination, attached 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.
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.
3. The orientation of the optical LPF is an important factor
for installation. If there is some marking on the 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 How to remove CCD board assembly and CCD
base assembly
1. Unsolder the CCD board assembly by the 14 points
(SD0) and then remove it.
2. Remove the two screws (1, 2) and remove the CCD base
assembly.
Note
a:
When removing the CCD base assembly, pay
0
heed to the CCD image sensor because the
spacer rubber and optical LPF are occasionally
removed together with the CCD image sensor.
Note 0b:
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 assemble CCD base assembly and CCD
board assembly
1. Install the optical LPF with the spacer rubber attached
to its CCD side in the OP block assembly.
Note
c:
Pay careful attention to the orientation of the LPF.
0
2. Set the CCD base assembly with careful attention to the
spacer rubber not to come off the right position, and fasten them together with the two screws (1, 2).
3. Set the CCD board assembly in the CCD base assem-
bly, and then solder it by the 14 points (SD0).
1.6.4 Replacement of service repair parts
The service repair parts for the OP Block Assembly are as
listed below.
Before replacement of these parts, remove the bracket (OP
assembly) as required.
Take special care not to disconnect any of the FPC wires or
cause any damage due to soldering (excessive heating).
1. Focusing motor
2. Zoom motor
3. Iris motor unit
Note
d:
When replacing the focusing motor or the zoom
0
motor, solder the FPC at a space of about 1 mm
above the terminal pin.
Note0e:
The iris motor unit includes the FPC Assembly and
two sensors.

1.7 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.

FG
Details
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].
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 seconds
or more. This error is defined as [E02].
In the case no REEL FG is produced for 4 seconds or more in the capstan rotation mode after 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.
Example (in case of the error number E01):
E01
UNIT IN
SAFEGUARD MODE
E01
REMOVE AND
REATTACH BATTERY
Possible cause
1. The mechanism is locked during mode shift.
2. The mechanism is locked at the mechanism loading
end, because the encoder position is skipped during
mechanism mode shift.
3. No power is supplied to the loading MDA.
1. The mechanism is locked during mode shift.
2. The mechanism is locked at the mechanism loading
end, because the encoder position is skipped during
mechanism mode shift.
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 overload 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
E05 –
E06 CAPSTAN 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 mechanism
mode is shifted to STOP with the pinch roller
set off.
–
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.

2.3 DISASSEMBLY/ASSEMBLY OF MECHANISM
ASSEMBLY
2.3.1 General statement
The mechanism should generally be disassembled/assembled in the EJECT mode (ASSEMBLY mode). (Refer to Fig.
2-3-1.)
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.

2.3.2 Explanation of mechanism mode
The mechanism mode of this model is classified into six
modes as shown in Table 2-3-1. Each mechanism mode
can be distinguished from others by the relative position
of “
” mark on the sub cam gear to the inner or outer protrusion on the main deck.
Refer to Fig. 2-3-2 to 2-3-8 below.
The EJECT mode, C IN mode and SHORT FF mode should
be recognized by the relative position of the “
” mark to
the inner protrusion, while the STOP mode, REV mode and
PLAY mode should be recognized by that to the outer protrusion.

2.5 CHECKUP AND ADJUSTMENT OF MECHANISM PHASE
<Connect gear> (Note 2)
<Rotary encoder>
Set the “■” of the rotary
part at the tapped hole
as shown in the figure.
Set the connect gear so
that its locating hole meets
the hole on the main deck
assembly.
<Worm wheel> (Note 2)
Set the worm wheel so
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 plate
together,set them together
so that their locating holes
meet the hole on the main
deck assembly.
<Connect gear 2> (Note 2)
Set the connect gear 2 so
that its locating hole meets
the hole on the main deck
assembly.
Note 1
<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.
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.
