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.

3.1.1 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

3.2.3 DISASSEMBLY OF [16] OP BLOCK ASSY/CCD BOARD ASSY
zPrecautions
(1) Be careful in handling the CCD IMAGE SENSOR, OPTICAL
LPF and the LENS components.
Pay special attention to the surfaces to protect them from
stains, dust, or scratches.
If the surfaces are soiled with finger prints or other stains,
wipe them off with silicon paper,
clean chamois leather, or recommended 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.
zDisassembly of OP BLOCK ASSY / CCD BOARD ASSY
(1) Remove the screw (1) to release the FPC.
NOTE16a:
When attaching, be careful not to fix the FPC tight with
the screw but give some play.
After tightening the screw, check if the FPC is mov-
able.
(2) Remove the screw (2), and then remove the HEAT SINK
(CCD).
NOTE16b:
Be careful in handling the parts.
NOTE16c:
When attaching, turn the SHIELD upward over the
HEAT SINK (CCD), and then tighten them with a
screw.
NOTE16d:
Be careful in handling the exclusive gel (heat com-
pound) that is applied to the back of the HEAT SINK
(CCD).
When the gel runs short due to part replacement, pre-
pare and apply new gel.
Apply the exclusive gel (heat compound) more than
3mm thick to each of the two marked areas on the
back of the HEAT SINK (CCD).
(3) Remove the two screws (3,4), and then remove the CCD
BOARD ASSY and the CCD BASE ASSY.
NOTE16e:
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.
NOTE16f:
Be careful in handling the CCD BASE ASSY as this
CCD BASE ASSY is surface mounted unlike previous
models.
When handling the CCD BOARD ASSY or removing
the FPC with the CCD BASE ASSY mounted, always
hold the side of the CCD BOARD ASSY to prevent
part detachment.
(4) Remove the SHEET and OP LPF.
NOTE16g:
When attaching the OP LPF, be careful with the at-
tachment direction.
(5) Unsolder the 28 soldered points (SD16a) on the CCD
BOARD ASSY, and then remove the CCD BASE ASSY.
NOTE16h:
Replace the CCD IMAGE SENSOR as a CCD BASE
ASSY, not as a single part replacement.
NOTE16j:
When removing the HOLDER (CCD), remove the two
screws (1,2) and the HEAT SINK (CCD) first as the
HOLDER (OP) is attached to the HEAT SINK (CCD).
zReplacement of service repair parts
The service repair parts on the OP BLOCK ASSY are as follows.
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) IRIS MOTOR UNIT
(4) ND FILTER UNIT
NOTE 16k:
When replacing the FOCUS MOTOR UNIT or the ZOOM
MOTOR UNIT, solder the FPC at a space of about 0.5 mm
above the terminal pin.
