48XV-SA600BK/XV-SA602SL3SECTION 1Important Safety Precautions1.1 Safety Precautions(1) This design of this product contains special hardware andmany circuits and components specially for safety purposes.For continued protection, no changes should be made to theoriginal design unless authorized in writing by themanufacturer. Replacement parts must be identical tothose used in the original circuits. Services should beperformed by qualified personnel only.(2) Alterations of the design or circuitry of the product shouldnot be made. Any design alterations of the product shouldnot be made. Any design alterations or additions will voidthe manufacturers warranty and will further relieve themanufacture of responsibility for personal injury or propertydamage resulting therefrom.(3) Many electrical and mechanical parts in the products havespecial safety-related characteristics. These characteris-tics are often not evident from visual inspection nor can theprotection afforded by them necessarily be obtained byusing replacement components rated for higher voltage,wattage, etc. Replacement parts which have these specialsafety characteristics are identified in the Parts List of ServiceManual. Electrical components having such features areidentified by shading on the schematics and by ( )on the Parts List in the Service Manual. The use of a sub-stitute replacement which does not have the same safetycharacteristics as the recommended replacement partsshown in the Parts List of Service Manual may createshock, fire, or other hazards.(4) The leads in the products are routed and dressed with ties,clamps, tubings, barriers and the like to be separated fromlive parts, high temperature parts, moving parts and/orsharp edges for the prevention of electric shock and firehazard. When service is required, the original lead routingand dress should be observed, and it should be confirmedthat they have been returned to normal, after reassembling.(5) Leakage shock hazard testing)After reassembling the product, always perform an isolationcheck on the exposed metal parts of the product (antennaterminals, knobs, metal cabinet, screw heads, headphonejack, control shafts, etc.) to be sure the product is safe tooperate without danger of electrical shock.Do not use a line isolation transformer during this check. Plug the AC line cord directly into the AC outlet. Using a“Leakage Current Tester“, measure the leakage currentfrom each exposed metal parts of the cabinet, particu-larly any exposed metal part having a return path to thechassis, to a known good earth ground. Any leakagecurrent must not exceed 0.5mA AC (r.m.s.). Alternate check methodPlug the AC line cord directly into the AC outlet. Use anAC voltmeter having, 1,000 ohms per volt or more sen-sitivity in the following manner. Connect a 1,500 10Wresistor paralleled by a 0.15 F AC-type capacitor be-tween an exposed metal part and a known good earthground.Measure the AC voltage across the resistor with the ACvoltmeter. Move the resistor connection to each exposed metalpart, particularly any exposed metal part having a returnpath to the chassis, and measure the AC voltage acrossthe resistor. Now, reverse the plug in the AC outlet andrepeat each measurement. Voltage measured any mustnot exceed 0.75 V AC (r.m.s.). This corresponds to 0.5mA AC (r.m.s.). 1.2 Warning(1) This equipment has been designed and manufactured tomeet international safety standards.(2) It is the legal responsibility of the repairer to ensure thatthese safety standards are maintained.(3) Repairs must be made in accordance with the relevantsafety standards.(4) It is essential that safety critical components are replacedby approved parts.(5) If mains voltage selector is provided, check setting for lo-cal voltage.1.3 CautionBurrs formed during molding may be left over on someparts of the chassis. Therefore, pay attention to such burrs in the case of pre-forming repair of this system.1.4 Critical parts for safetyIn regard with component parts appearing on the silk-screenprinted side (parts side) of the PWB diagrams, the parts that areprinted over with black such as the resistor ( ), diode ( )and ICP ( ) or identified by the “ “ mark nearby are criticalfor safety. When replacing them, be sure to use the parts of the same typeand rating as specified by the manufacturer. (Except the JC version)Good earth groundPlace this probe on each exposedmetal part.AC VOLTMETER(Having 1000 ohms/volts,or more sensitivity)1500 10W0.15 F AC TYPEXV-SA600BK/XV-SA602SL41.5 Preventing static electricityElectrostatic discharge (ESD), which occurs when static electricity stored in the body, fabric, etc. is discharged, can destroy the laser diode in the traverse unit (optical pickup). Take care to prevent this when performing repairs.1.5.1 Grounding to prevent damage by static electricityStatic electricity in the work area can destroy the optical pickup (laser diode) in devices such as DVD players. Be careful to use proper grounding in the area where repairs are being performed. (1) Ground the workbenchGround the workbench by laying conductive material (such as a conductive sheet) or an iron plate over it before placing thetraverse unit (optical pickup) on it.(2) Ground yourselfUse an anti-static wrist strap to release any static electricity built up in your body. (3) Handling the optical pickup(1) In order to maintain quality during transport and before installation, both sides of the laser diode on the replacement op-tical pickup are shorted. After replacement, return the shorted parts to their original condition. (Refer to the text.)(2) Do not use a tester to check the condition of the laser diode in the optical pickup. The tester's internal power source caneasily destroy the laser diode. 1.6 Handling the traverse unit (optical pickup)(1) Do not subject the traverse unit (optical pickup) to strong shocks, as it is a sensitive, complex unit. (2) Cut off the shorted part of the flexible cable using nippers, etc. after replacing the optical pickup. For specific details, refer to thereplacement procedure in the text. Remove the anti-static pin when replacing the traverse unit. Be careful not to take toolong a time when attaching it to the connector. (3) Handle the flexible cable carefully as it may break when subjected to strong force. (4)I t is not possible to adjust the semi-fixed resistor that adjusts the laser power. Do not turn itConductive material (conductive sheet) or iron plate(caption)Anti-static wrist strapXV-SA600BK/XV-SA602SL51.7 Importance admistering point on the safety N B C D 5 3 4 2 4 Q953 D971 B4 B3 R992 EP902 B516 B13 R981 C1 C2 C5 C971 C707 C711 C714 C716 C717 C730 C731 C737 C738 C740 C741 C742 C743 C744 C745 C746 C747 C750 C751 C752 C753 C754 C755 C756 C757 C761 C762 C771 C772 C801 B399 C806 IC1100 C808 C1100 C810 C812 C813 C814 C815 C1101 C817 C818 B52 C902 C903 C905 C906 C907 C908 C909 B433 C913 C914 B157 C960 C962 C963 C965 C966 C969 C985 C978 C979 C982 C984 C987 C989 B711 C997 C1701 C1702 CN701 CN801 CP951 B319 B320 B216 B75 L1701 D901 D902 D903 D904 D908 B44 B78 C991 D951 D952 D954 D956 D957 D960 D991 DI1 EP711 EP951 FC901 FC902 C992 B89 D998 IC901 J700 J701 J702 J703 J801 J802 J804 CN802 HS952 K801 K902 L709 L710 B88 L901 L952 L955 L957 L959 PC901 B77 Q743 Q744 Q753 Q754 Q755 Q756 Q951 Q991 B308 Q21 R711 R712 R713 R715 R726 R731 R740 R741 R742 R743 R1500 R746 R748 R750 R751 R752 R753 R1501 R756 R758 R761 R762 R764 R765 R766 R767 R771 R772 R774 R775 R776 R777 R780 R781 R782 R783 R790 R791 R792 R793 R797 R818 X1 B5 R901 R903 R905 R906 R907 R908 R920 R956 R1721 RA1 RA2 RA3 S801 T901 T1701 Q22 B15 B17 B18 B19 B20 B21 B12 B24 B25 B26 B27 B28 B29 B30 B31 B32 B33 B34 B35 B36 B37 B38 B39 B80 B40 D828 B42 B43 B515 B45 B46 B48 B49 B50 B55 B54 B229 B56 B57 B58 B875 B61 B62 B64 B65 B66 B67 D9
