24、CTION 1 PRECAUTION 1.1Safety Precautions (1) This design of this product contains special hardware and many circuits and components specially for safety purpos- es. For continued protection, no changes should be made to the original design unless authorized in writing by the manufacturer. Replacemen

25、t parts must be identical to those used in the original circuits. Services should be per- formed by qualified personnel only. (2) Alterations of the design or circuitry of the product should not be made. Any design alterations of the product should not be made. Any design alterations or additions wi

26、ll void the manufacturers warranty and will further relieve the manufacture of responsibility for personal injury or property damage resulting therefrom. (3) Many electrical and mechanical parts in the products have special safety-related characteristics. These characteris- tics are often not eviden

27、t from visual inspection nor can the protection afforded by them necessarily be obtained by us- ing replacement components rated for higher voltage, watt- age, etc. Replacement parts which have these special safety characteristics are identified in the Parts List of Ser- vice Manual. Electrical comp

28、onents having such features are identified by shading on the schematics and by ( ) on the Parts List in the Service Manual. The use of a substitute replacement which does not have the same safety charac- teristics as the recommended replacement parts shown in the Parts List of Service Manual may cre

29、ate shock, 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 from live parts, high temperature parts, moving parts and/or sharp edges for the prevention of electric shock and fire hazard. When service is req

30、uired, the original lead routing and dress should be observed, and it should be confirmed that they have been returned to normal, after reassem- bling. 1.2Warning (1) This equipment has been designed and manufactured to meet international safety standards. (2) It is the legal responsibility of the r

31、epairer to ensure that these safety standards are maintained. (3) Repairs must be made in accordance with the relevant safety standards. (4) It is essential that safety critical components are replaced by approved parts. (5) If mains voltage selector is provided, check setting for local voltage. 1.3

32、Caution Burrs formed during molding may be left over on some parts of the chassis. Therefore, pay attention to such burrs in the case of pre- forming repair of this system. 1.4Critical parts for safety In regard with component parts appearing on the silk-screen printed side (parts side) of the PWB d

33、iagrams, the parts that are printed over with black such as the resistor ( ), diode ( ) and ICP ( ) or identified by the mark nearby are critical for safety. When replacing them, be sure to use the parts of the same type and rating as specified by the manufacturer. (This regulation dose not Except t

34、he J and C version) 1.5Remote control The Lithium battery is in danger of explosion if replaced incor- rectly. Replace it only with the same or equivalent type. 1.6Preventing static electricity Electrostatic discharge (ESD), which occurs when static electric- ity stored in the body, fabric, etc. is

35、discharged, can destroy the laser diode in the traverse unit (optical pickup). Take care to pre- vent this when performing repairs. 1.6.1 Grounding to prevent damage by static electricity Static electricity in the work area can destroy the optical pickup (laser diode) in devices such as laser produc

36、ts. Be careful to use proper grounding in the area where repairs are being performed. (1) Ground the workbench Ground the workbench by laying conductive material (such as a conductive sheet) or an iron plate over it before plac- ing the traverse unit (optical pickup) on it. (2) Ground yourself Use a

37、n anti-static wrist strap to release any static electricity built up in your body. (3) Handling the optical pickup In order to maintain quality during transport and before installation, both sides of the laser diode on the replace- ment optical pickup are shorted. After replacement, re- turn the sho

38、rted parts to their original condition. (Refer to the text.) Do not use a tester to check the condition of the laser di- ode in the optical pickup. The testers internal power source can easily destroy the laser diode. 1M Conductive material (conductive sheet) or iron plate (caption) Anti-static wris

39、t strap (No.MA596)6/28 1.7Handling 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 de

40、tails, refer to the replacement procedure in the text. Remove the anti-static pin when replacing the traverse unit. Be careful not to take too long a time when attaching it to the connec- tor. (3) Handle the flexible cable carefully as it may break when subjected to strong force. (4) I t is not poss

41、ible to adjust the semi-fixed resistor that ad- justs the laser power. Do not turn it. 1.8Attention when traverse unit is decomposed *Please refer to Disassembly method in the text for the pickup unit. Apply solder to the short land sections before the card wire is disconnected from the connector on

42、 the servo board. (If the card wire is disconnected without applying solder, the pickup may be destroyed by static electricity.) In the assembly, be sure to remove solder from the short land sections after connecting the card wire. 1.9Important for laser products SOLDER 1.CLASS 1 LASER PRODUCT 2.CAU

43、TION : (For U.S.A.) Visible and/or invisible class II laser radiation when open. Do not stare into beam. (Others) Visible and/or invisible class 1M laser radiation when open. Do not view directly with optical instruments. 3.CAUTION : Visible and/or invisible laser radiation when open and inter lock

44、failed or defeated. Avoid direct exposure to beam. 4.CAUTION : This laser product uses visible and/or invisible laser radiation and is equipped with safety switches which prevent emission of radiation when the drawer is open and the safety interlocks have failed or are defeated. It is dangerous to d

45、efeat the safety switches. 5.CAUTION : If safety switches malfunction, the laser is able to function. 6.CAUTION : Use of controls, adjustments or performance of procedures other than those specified here in may result in hazardous radiation exposure. ! Please use enough caution not to see the beam d

This damag

47、e may take due to improper part replacement with a external equipment via RCA line. 2.1.2Repair Procedure (1) Check the shorted circuit at the meltdown point. Need to clean up if the shorted circuit or carbonization happen at the fuse pattern. (2) Add following part on the fuse pattern. (3) Check ou
