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.

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.

· Precautions during Servicing

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.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.

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.

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.

SECTION 1 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 of 0.088N·m(0.9kgf·cm). 1.1.2 Assembly and disassembly

1.6 DISASSEMBLY/ASSEMBLY OF 0 OP BLOCK ASSEMBLY/CCD BOARD ASSEMBLY 1.6.1 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. 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. The orientation of the optical LPF is an important factor for installation. If there is some marking on the LPF, be sure to note it down before removing and to reassemble it very carefully as it was referring to the marking. 1.6.2 How to remove CCD board assembly and CCD base assembly 1. Unsolder the CCD board assembly by the 14 points (SD0) and then remove it. 2. Remove the two screws (1, 2) and remove the CCD base assembly. Note0a: When removing the CCD base assembly, pay heed to the CCD image sensor because the spacer rubber and optical LPF are occasionally removed together with the CCD image sensor. Note 0b: When replacing the CCD image sensor, don't replace it individually but replace the CCD base assembly in whole with a new one.

1.6.3 How to assemble CCD base assembly and CCD board assembly 1. Install the optical LPF with the spacer rubber attached to its CCD side in the OP block assembly. Note0c: Pay careful attention to the orientation of the LPF. 2. Set the CCD base assembly with careful attention to the spacer rubber not to come off the right position, and fasten them together with the two screws (1, 2). 3. Set the CCD board assembly in the CCD base assembly, and then solder it by the 14 points (SD0). 1.6.4 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 assembly) as required. Take special care not to disconnect any of the FPC wires or cause any damage due to soldering (excessive heating). 1. Focusing motor 2. Zoom motor 3. Iris motor unit Note0d: When replacing the focusing motor or the zoom motor, solder the FPC at a space of about 1 mm above the terminal pin. Note0e: The iris motor unit includes the FPC Assembly and two sensors.

Note 7c: Since the slide guide plate assembly controls the slide deck assembly so that it exactly slides the main deck assembly, it must exactly be assembled in the PLAY mode. Therefore, temporarily fix the slide guide plate assembly in this stage. For details of reassembling procedure, refer to "2.6.1 Assembling slide deck assembly and main deck assembly" . Note 7d: The pad arm assembly controls the tension level of the tension arm assembly. For adjustment of the tension arm assembly, refer to "2.6.2 Locating tension pole". Note 7e: When reinstalling the load brake assembly, slightly lift the slide deck assembly upwards because the lower part of the load brake assembly sticks out of the slide deck assembly.

2.5 CHECKUP AND ADJUSTMENT OF MECHANISM PHASE

Set the "I" of the rotary part at the tapped hole as shown in the figure.

(Note 2) Set the connect gear so that its locating hole meets the hole on the main deck assembly.

(Note 2) Set the worm wheel so that its locating hole meets the hole on the main deck assembly.

Note 1
After fitting the main cam gear and brake control plate together,set them together so that their locating holes meet the hole on the main deck assembly.

(Note 2) Set the connect gear 2 so that its locating hole meets the hole on the main deck assembly.

Set the sub cam gear so that its locating hole meets the hole on the main deck assembly. This state represents that the mechanism is in the EJECT mode, which is the "mechanism assembly mode".

Note 1: Since the connect gear 2 is tightly fixed to the main deck by caulking, adjust its phase with the connect gear and sub cam gear.

Note 2: The part that needs phase adjustment by the hole on the main deck assembly must exactly be set as the specified phase. There is a fear that some part is installed in a wrong phase because assembling of the mechanism is automated. If so, set every part in the correct phase whenever the mechanism is reassembled.

2.8.1 Tape pattern check (1) Play back the compatibility adjustment tape. (2) While triggering the MAIN CN105-21PIN (HID1), observe the waveform of CN105-20PIN (ENV_OUT). (3) Confirm that the waveform is free from remarkable level-down, and entirely parallel and straight. Moreover, perform the following adjustment as required. (4) In case any level-down is observed on the left hand side, straighten the level by turning the guide roller of the pole base assembly (supply). In case any level-down is observed on the right hand side, however, straighten the level by turning the guide roller of the pole base assembly (Take-up). (5) After adjustment, try the unloading motion once, and confirm that the waveform is flat (straight) when the tape has been played back again. Moreover, perform readjustment as required. (6) When the recording has been played back again, play back the self-recording to confirm that the waveform is flat. Note: When an adjustment is performed with the lower case cover attached, first slide the plate open (adjustment hole plate) and then perform the compatibility adjustment. Be sure not to damage the cover plate (adjustment hole plate) when sliding it open to make an adjustment because it must be re-positioned after completing the adjustment.
