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.

3.2.4 ASSEMBLY/DISASSEMBLY OF [20] OP BLOCK ASSEMBLY/CCD BOARD ASSEMBLY

zPrecautions

(1) Take care in handling the CCD IMAGE SENSOR, OPTICAL

LPF and lens components when 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 sil-

icon 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) As the attachment direction of the OPTICAL LPF is im-

portant, be careful when removing it. Make sure to reat-

tach the OPTICAL LPF in its original direction.

zDisassembly of OP BLOCK ASSEMBLY / CCD BOARD AS-

SEMBLY

(1) Remove the two screws (1, 2), and then remove the BKT

(OP) ASSY.

(2) Be careful in handling the SPACER and the CONNEC-

TOR that connects the CDS BOARD ASSY and the CCD

BOARD ASSY. Remove the CDS BOARD ASSY by pull-

ing it parallel to the CCD BOARD ASSY.

(3) Remove the two screws (3, 4), and then remove the CCD

BOARD ASSY, SHIELD (CCD), HEAT SHEET (CCD),

and the CCD BASE ASSY.

NOTE20a:

Be careful in handling as there are only the OPTICAL

LPF and the SHEET stored inside the OP BLOCK

ASSY when the CCD BASE ASSY is removed.

(4) Remove the SHEET and the OPTICAL LPF.

(5) Unsolder the 24 solder points (SD20a), remove the two

screws (5, 6), and then remove the CCD BASE ASSY.

NOTE20b:

Replace the CCD image sensor as a whole unit of CCD

BASE ASSY instead of replacing it as a single part.

(6) Detach the HEAT SHEET (CCD), and remove the

SHIELD (CCD) from the CCD BOARD ASSY.

zAssembly of OP BLOCK ASSEMBLY / CCD BOARD AS-

SEMBLY

(1) Set the SHIELD (CCD) first, then the HEAT SHEET

(CCD), and then the CCD BASE ASSY to the CCD

BOARD ASSY, and tighten them with the screws (5, 6).

(2) Solder the 24 solder points (SD20a) on the CCD BOARD

ASSY.

(3) Set the OPTICAL LPF first, and then the SHEET to the

OP BLOCK ASSEMBLY.

NOTE20c:

When attaching the OPTICAL LPF, be careful with the

attachment direction to avoid any uplift or unevenness

for the sheet attachment.

(4) Attach the CCD BOARD ASSY (CCD BASE ASSY and

others), and then tighten them with the two screws (3, 4).

zReplacement of service repair parts

The service repair parts for the OP BLOCK ASSEMBLY are as

listed below.Take special care not to disconnect any of the FPC

wires or cause any damage due to soldering (excessive heating).

(1) FOCUS MOTOR UNIT

(2) ZOOM MOTOR UNIT

(3) AUTO IRIS UNIT

NOTE20d:

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.

ADJUSTMENT

4.1 PREPARATION

4.1.1 Precaution

Camera system and deck system of this model are specially

adjusted by using PC.

However, if parts such as the following are replaced, an

adjustment is required. The adjustment must be performed in a

Service Center equipped with the concerned facilities.

• OP BLOCK ASSEMBLY

• MONITOR ASSEMBLY

• EEP ROM (IC4502 of MAIN board)

In the event of malfunction with electrical circuits, first find a

defective portion with the aid of proper test instruments as shown

in the following electrical adjustment procedure, and then

commence necessary repair/ replacement/adjustment.

• In observing chip TP, use IC clips, etc. to avoid any stress.

Prior to replacement of chip parts (especially IC), remove the

solder completely to prevent peeling of the pattern.

• Use a patch cord if necessary. As for a patch cord, see the

BOARD INTERCONNECTIONS.

• Since connectors are fragile, carefully handle them in

disconnecting and connecting the FPC.

4.1.2 REQUIRED TEST EQUIPMENT

• Personal computer (for Windows)

• Color TV monitor

• Oscilloscope (dual-trace type, observable 100MHz or higher

frequency). The one observable 300 MHz or higher frequency

is recommended.

• Digital voltmeter

• DC power supply or AC adapter

• Frequency counter (with threshold level adjuster)

4.1.3 TOOLS REQUIRED FOR ADJUSTMENT

•Torque driver

Be sure to use to fastening the mechanism and exterior parts

because those parts must strictly be controlled for tightening

torque.

•Bit

This bit is slightly longer than those set in conventional torque

drivers.

•Tweezers

To be used for removing and installing parts and wires.

•Chip IC replacement jig

To be used for adjustment of the camera system.

NOTE:

1 ) and (This mark shows where to attach the screws) : Do not reuse the screws because the screw lock bond was applied to prevent the screws from loosening.

Prepare the specified screws and use them in place of the removed screws.

2 )Tightening torque for the screws

There are setting limits of the torque value for the torque driver. If the value exceeds the setting value, take it as a rough measurement (reference value),

and tighten the screw manually.

The specified torque value is a recommended value of the initial assembly. Therefore, set the value below the specified torque value in the assembling procedure.
