(No.MA248)1-7 SECTION 1 PRECAUTIONS 1.1Safety Precautions ! Burrs formed during molding may be left over on some parts of the chassis. Therefore, pay

34、attention to such burrs in the case of preforming repair of this system. ! Please use enough caution not to see the beam directly or touch it in case of an adjustment or operation check. 1-8 (No.MA248) 1.2Preventing static electricity Electrostatic discharge (ESD), which occurs when static electrici

35、ty 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. 1.2.1 Grounding to prevent damage by static electricity Static electricity in the work area can destroy the optical pickup (laser d

36、iode) in devices such as DVD players. 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 placing the traverse unit (optical pickup)

37、on it. (2) Ground yourself Use an 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 replacement optical pickup are shorted. After

38、 replacement, return the shorted parts to their original condition. (Refer to the text.) Do not use a tester to check the condition of the laser diode in the optical pickup. The testers internal power source can easily destroy the laser diode. 1.3Handling the traverse unit (optical pickup) (1) Do no

39、t 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 the replacement procedure in the text. Remove the anti-static p

40、in when replacing the traverse unit. Be careful not to take too long a time when attaching it to the connector. (3) Handle the flexible cable carefully as it may break when subjected to strong force. (4) It is not possible to adjust the semi-fixed resistor that adjusts the laser power. Do not turn i

41、t. 1.4Attention when traverse unit is decomposed *Please refer to Disassembly method in the text for the DVD pickup unit. Apply solder to the short land before the flexible wire is disconnected from the connector on the DVD pickup unit. (If the flexible wire is disconnected without applying solder,

42、the DVD pickup may be destroyed by static electricity.) In the assembly, be sure to remove solder from the short land after connecting the flexible wire. 1M (caption) Anti-static wrist strap Conductive material (conductive sheet) or iron plate Mechanism control board CN101 Flexible wire Short-circui

Avoid direct exposure to beam. 3.CAUTION : There are no serviceable parts inside the Laser Unit. Do not disassemble the Laser Unit. Replace

44、 the complete Laser Unit if it malfunctions. 4.CAUTION : The CD,MD and DVD player uses 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 defeat the safet
