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.

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.

Externally exposed accessible part

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

BOARD ASSEMBLIES

1.5.1 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 recommended 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.

1.5.3 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).

1.5.4 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 assyembly) as required. Take special care not to disconnect any of the FPC wires or cause any damage due to soldering (excessive heating).

Be careful not to damage the FPC or the connector when removing the Monitor Cover Assembly.

Be careful not to damage the parts when removing or mounting the Hinge Assembly.

To unplug the FPC, release only the lock of the connector and remove the FPC together with the Hinge Assembly.

As the backlight is soldered at two points on the Monitor Board Assembly, the solder should be removed when disassembling the backlight as a single part.

Take care when handling the FPC. Be careful not to lose the magnets and attach

them in the correct orientation. When mounting the FPC Assembly, wrap it around

the Hinge Assembly by 3-1/2 turns.

1.7 MANUAL EJECTION OF THE CASSETTE TAPE

The following procedure describes a simplified method

Note:

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.

This helps prevent the tape from being damaged when

Note:

the Cassette Housing Assembly is moved upward at the unloading end.

(DC3V)

4. In order to change the mechanism mode at the unloading end apply 3 V, DC to the electrode on the top surface 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 Assembly.

6. Peel off the PVC tape and take out the cassette tape from the cassette housing.

Make sure that grease or a similar substance is not

Note:

attached to the surface of the tape.

Similarly, also make sure that grease or a similar sub-

stance is not attached on the Mechanism
