10、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

11、 being serviced. Fig.1 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 com- ply with these and other cautionary notices appearing in the operation and service manuals.

12、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 va

13、rious 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 i

14、nsulated wires 3) High voltage leads 5.Use specified insulating materials for hazardous live parts. Note especially: 1) Insulation Tape3) Spacers5) Barrier 2) PVC tubing4) Insulation sheets for transistors 6.When replacing AC primary side components (transformers, power cords, noise blocking capacit

15、ors, etc.) wrap ends of wires securely about the terminals before soldering. 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

16、 are specified for compliance with recognized codes pertaining to X-ray emission. Consequently, when servicing these products, replace the cath- ode ray tubes and other parts with only the specified parts. Under no circumstances attempt to modify these circuits. Unauthorized modification can increas

17、e the high voltage value and cause X-ray emission from the cathode ray tube. 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

18、 replacing the connectors is unavoidable, in or- der 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

19、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). Fig.7 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 avo

20、id frayed conductors. 15 mm Fig.4 (3) Align the lengths of the wires to be connected. Insert the wires fully into the connector. Connector Metal sleeve Fig.5 (4) As shown in Fig.6, use the crimping tool to crimp the metal sleeve at the center position. Be sure to crimp fully to the complete closure

21、of the tool. 1 vPrecautions during Servicing 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 o

22、f force in any direction will not loosen it. 1.25 2.0 5.5 Crimping tool Fig.6 (5) Check the four points noted in Fig.7. Not easily pulled free Crimped at approx. center of metal sleeve Conductors extended Wire insulation recessed more than 4 mm S40888-01 vSafety Check after Servicing Examine the are

23、a 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 compli- ance with safety standards. 1.Insulation resistance test

24、 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

25、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 circui

26、t components, confirm specified clearance distance (d), (d) be- tween soldered terminals, and between terminals and surrounding metallic parts. See table 1 below. 4.Leakage current test Confirm specified or lower leakage current between earth ground/power cord plug prongs and externally exposed acce

27、ssible 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 accessi- ble parts. Use an AC voltmeter to measure across

28、 both terminals of load Z. See figure 9 and following table 2. 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: Conn

29、ect milli ohm meter between earth pin in AC inlet and exposed accessible parts. See figure 10 and grounding specifications. d d Chassis Power cord, primary wire Region USA SCOR,SQCK,SQSO XLAT , E_STI , E_ENB , E_DR RF XLAT , LDON IC401 CS4391 XIO1,XIO ,XIO10 /SRST F_CLK F_OUT PCMCLK ALE MSDATO MDP1
