(No.YF200)1-3 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.

1-4 (No.YF200) 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. Fig.1-1-10 Fig.1-1-11 Fig.1-1-12 NOTE : These tables are unofficial and for reference only.

1-6 (No.YF200) SECTION 3 DISASSEMBLY 3.1 BEFORE ASSEMBLY AND DISASSEMBLY 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 otherwise specified, tighten screws at a torque of 0.078N·m (0.8kgf·cm). However, as this is a required value at the time of production, use the value as a measuring stick when proceeding repair services. (See "SERVICE NOTE" as for tightening torque.) 3.1.2 Destination of connectors 3.1.3 Disconnection of connectors (Wires) Fig.3-1-1 3.1.4 Tools required for disassembly and assembly Fig.3-1-2 • 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 replacement of IC. • Cleaning cloth Recommended cleaning cloth to wipe down the video heads, mechanism (tape transport system), optical lens surface. 3.2 ASSEMBLY AND DISASSEMBLY OF MAIN PARTS 3.2.1 Assembly and disassembly When reassembling, perform the step(s) in reverse order.
