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 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: 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. Fig.4 (3) Align the lengths of the wires to be connected. Insert the wires fully into the connector. 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. 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.

Crimping tool
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.

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. Chassis 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.

1.3 Manually removing the cassette tape The following procedure describes a simplified method 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 the Cassette housing assembly is moved upward at the unloading end. (4) Apply DC3V to the electrode on the top surface of the Loading motor assembly to set the Mechanism assembly to the eject mode. Unloading end is eject mode. (5) If there is any slack tape in the tape transport system, wind it inside the cassette tape by turning the Reel disk (SUP) 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 attached to the surface of the tape. Similarly, also make sure that grease or a similar substance is not attached on the Mechanism assembly.

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.

3.2 Mechanism compatibility adjustment 3.2.1 Tape pattern check (1) Play back the tape for compatibility adjustment. (2) Apply the external trigger signal to HID1, to observe the waveform of the ENV_OUT. (3) Set to the manual tracking mode (ATF OFF). (4) Make sure that there is no significant level drop of the waveform caused by the tracking operation, with its generally parallel and linear variation ensured. Perform the following adjustments when required. (5) Reduce the waveform by the tracking operation. If a drop in level is found on the left side, turn the guide roller (supply side) to make the waveform linear. If a drop in level is on the right side, likewise turn the guide roller (take-up side) to make it linear. (6) Unload the cassette tape once, play back the tape again and confirm that the waveform is flat. (7) Record at the recording tape, and play back the recorded signal. (8) Confirm that the waveform is flat.
