SECTION 1
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 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
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 components (transformers,
power cords, noise blocking capacitors, etc.) wrap ends of
wires securely about the terminals before soldering.
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.
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
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).
Fig.1-1-3
b) 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.
Fig.1-1-4
c) Align the lengths of the wires to be connected.
Insert the wires fully into the connector.
Fig.1-1-5
d) As shown in Fig.1-1-6, 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.
Fig.1-1-6
e) Check the four points noted in Fig.1-1-7.

1.1.2 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 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.
Fig.1-1-8
(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 Fig.1-1-9
and following Fig.1-1-12.
Fig.1-1-9
(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 Fig.1-1-10 and grounding
specifications.

3.2.3 Assembly/Disambly of [14] OP BLOCK ASSY/CCD BOARD ASSY
zPrecautions
(1) Be careful in handling the CCD IMAGE SENSOR, OPTI-
CAL LPF and the LENS components. Pay special atten-
tion not to soil or damage the surfaces., 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 ASSY.
(3) As the CUSHION(OP) protects the OP BLOCK ASSY
from scratches or damages, leave the CUSHION as
long as it does not interfere with the procedure.
zDisassembly of OP BLOCK ASSEMBLY / CCD BOARD AS-
SEMBLY
(1) Unsolder the fourteen soldered points (SD11a) of the
CCD BOARD ASSY.
(2) Remove the two screws (1,2), and then remove the CCD
BOARD ASSY and the CCD BASE ASSY.
NOTE11a:
When removing the CCD BASE ASSY, be careful in
handling as the CCD IMAGE SENSOR may be re-
moved together with the SHEET and the OP LPF at-
tached.
NOTE11\b:
Replace the CCD IMAGE SENSOR as a CCD BASE
ASSY, not as a single part replacement.
zAssembly of OP BLOCK ASSEMBLY / CCD BOARD AS-
SEMBLY
(1) Set the OPTICAL LPF first, and then the SHEET to the
OP BLOCK ASSY.
NOTE11c:
Be careful with the attachment direction of the OP
LPF.
(2) Attach the CCD BASE ASSY first, then the CCD BASE
ASSY so that the SHEET stays in place, and then tighten
with the two screws (1, 2).
(3) Solder the 14 points (SD11a) on the CCD BOARD AS-
SY.
zReplacement of service repair parts
The service repair parts for the OP BLOCK ASSY are as listed
below.
When replacing the parts, remove the BKT OP (1) and (2) first
if necessary.
When replacing parts, be careful not to cut the FPCs or dam-
age any parts by soldering (excessive heat).
(1) FOCUS MOTOR UNIT
(2) ZOOM MOTOR UNIT
(3) AUTO IRIS UNIT
NOTE 13e:
When replacing the FOCUS MOTOR UNIT or the ZOOM

3.3 DVC MECHANISM
3.3.1 TOOLS REQUIRED FOR ADJUSTMENTS
1. Torque driver
Be sure to use to fastening the mechanism and exterior parts
because those parts must strictly be controlled for tightening
torque.
Torque setting value of torque driver is limited. At the values
over the maximum torque setting value, fasten a screw manu-
ally not to damage the screw thread.
2. Bit
This bit is slightly longer than those set in conventional torque
drivers.
3. Tweezers
To be used for removing and installing parts and wires.
4. Chip IC replacement jig
To be used for replacement of part.
5.Guide driver
To be used for the height adjustment such as the guide rollers.
6. Cleaning cloth
Recommended cleaning cloth to wipe down the video heads,
mechanism (tape transport system), optical lens surface.
3.3.2 Precautions
(1) When fastening parts, pay careful attention to the tightening torque of each screw. Unless otherwise specified, tighten a screw
with the torque of 0.055 N
·m (0.56 kgf·cm).
(2) Be sure to disconnect the set from the power supply before fastening and soldering parts.
(3) When disconnecting/connecting wires, be careful not to get them and their connectors damaged.
(4) When replacing parts, be very careful neither to damage other parts nor to fit wrong parts by mistake.

3.3.4 DISASSEMBLY AND ASSEMBLY OF MECHANISM ASSEMBLY
3.3.4.1 General statement
The mechanism should be disassembled/assembled in the
CASS IN mode (ASSEMBLY mode). (Refer to Fig. 3-3-2,3-3-5.)
When the mechanism assembly is removed from the main body,
it is generally set in the STOP mode.
After the mechanism assembly is removed from the main body,
it is required to forcibly supply 3V DC to the LOADING MOTOR
to unload, and then set the CASS IN mode.

3.3.4.2 Mechanism modes
The mechanism mode of this model is classified into five modes
as shown in Fig. 3-3-9. Each mechanism mode can be distin-
guished from others by the relative position of “ ”, “ ”, “ ”
marks on the sub cam gear to the inner or outer protrusion on the
main deck. Refer to Fig. 3-3-3 to 3-3-8 below.
