9、neral Safety Safety regulations require that during a repair: . Connect the unit to the mains via an isolation transformer. . Replace safety components indicated by the symbol , only by components identical to the original ones. Any other component substitution (other than original type) may increas

10、e risk of fire or electrical shock hazard. Safety regulations require that after a repair, you must return the unit in its original condition. Pay, in particular, attention to the following points: . Route the wires/cables correctly, and fix them with the mounted cable clamps. . Check the insulation

11、 of the mains lead for external damage. . Check the electrical DC resistance between the mains plug and the secondary side: 1) Unplug the mains cord, and connect a wire between the two pins of the mains plug. 2) Set the mains switch the “ on” position (keep the mains cord unplug). 3) Measure the res

12、istance value between the mains plug and the front panel, controls, and chassis bottom. 4) Repair or correct unit when the resistance measurement is less than 1M. 5) Verify this, before you return the unit to the customer/user (ref. UL- standard no. 1492). 6) Switch the unit “ off” , and remove the

13、wire between the two pins of the mains plug. 2. Laser Safety This unit employs a laser. Only qualified service personnel may remove the cover, or attempt to service this device (due to possible eye injury). Laser device unit Type : Semiconductor laser GaAlAs Wavelength : 650nm (DVD) : 780nm (VCD/CD)

14、 Output power : 7mW (VCD/CD) : 10mW (DVD) Beam divergence: 60 degree Note: Use of controls or adjustments or performance of procedure other than those specified herein, may result in hazardous radiation exposure. Avoid direct exposure to beam. Safety Instructions, Warnings, Notes 1- 3 RadioFans.CN 收

15、音机爱 好者资料库 Warnings 1. General . All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD). Careless handing during repair can reduce life drastically. Make sure that, during repair, you are at the same potential as the mass of the set by a wristband with resistance. Kee

16、p components and tools at this same potential. Available ESD protection equipment: 1) Complete kit ESD3 (small tablemat, wristband, connection box, extension cable and earth cable) 4822 310 10671. 2) Wristband tester 4822 344 13999. . Be careful during measurements in the live voltage section. The p

17、rimary side of the power supply, including the heat sink, carries live mains voltage when you connect the player to the mains (even when the player is “ off” !). It is possible to touch copper tracks or components in this unshielded primary area, when you service the player. Service personnel must t

18、ake precautions to prevent touching this area or components in this area. A “ lighting stroke” and a stripe- marked printing on the printed wiring board, indicate the primary side of the power supply. . Never replace modules, or components, while the unit is “ on” . 2. Laser . The use of optical ins

19、truments with this product, will increase eye hazard. . Only qualified service personnel may remove the cover or attempt to service this device, due to possible eye injury. . Repair handing should take place as much as possible with a disc loaded inside the player. . Text below is placed inside the

20、unit, on the laser cover shield: Notes: Manufactured under licence from Dolby Laboratories. The double- D symbol is trademark of Dolby Laboratories, Inc. All rights reserved. CAUTION: VISIBLE AND INVISIBLE LASER RADIATION WHEN OPEN, AVOID EXPOSURE TO BEAM. 1- 4 Lead- Free Requirement for Service IND

21、ENTIFICATION: Regardless of special logo (not always indicated) One must treat all sets from 1.1.2005 onwards, according next rules. Important note: In fact also products a little older can also be treated in this way as long as you avoid mixing solder- alloys (leaded/ lead- free). So best to always

22、 use SAC305 and the higher temperatures belong to this. Due to lead- free technology some rules have to be respected by the workshop during a repair: Use only lead- free solder alloy Philips SAC305 with order code 0622 149 00106. If lead- free solder- paste is required, please contact the manufactur

23、er of your solder- equipment. In general use of solder- paste within workshops should be avoided because paste is not easy to store and to handle. Use only adequate solder tools applicable for lead- free solder alloy. The solder tool must be able o To reach at least a solder- temperature of 400 C, o

24、 To stabilize the adjusted temperature at the solder- tip o To exchange solder- tips for different applications. Adjust your solder tool so that a temperature around 360 C 380 C is reached and stabilized at the solder joint. Heating- time of the solder- joint should not exceed 4 sec. Avoid temperatu

25、res above 400 C otherwise wear- out of tips will rise drastically and flux- fluid will be destroyed. To avoid wear- out of tips switch off un- used equipment, or reduce heat. Mix of lead- free solder alloy / parts with leaded solder alloy / parts is possible but PHILIPS recommends strongly to avoid

26、mixed solder alloy types (leaded and lead- free). If one cannot avoid, clean carefully the solder- joint from old solder alloy and re- solder with new solder alloy (SAC305). Use only original spare- parts listed in the Service- Manuals. Not listed standard- material (commodities) has to be purchased

27、 at external companies. Special information for BGA- ICs: - always use the 12nc- recognizable soldering temperature profile of the specific BGA (for de- soldering always use highest lead- free temperature profile, in case of doubt) - lead free BGA- ICs will be delivered in so- called dry- packaging

28、(sealed pack including a silica gel pack) to protect the IC against moisture. After opening, dependent of MSL- level seen on indicator- label in the bag, the BGA- IC possibly still has to be baked dry. This will be communicated via AYS- website. Do not re- use BGAs at all. For sets produced before 1

29、.1.2005, containing leaded soldering- tin and components, all needed spare- parts will be available till the end of the service- period. For repair of such sets nothing changes. On our website: www.atyourservice.ce.P You find more information to: BGA- de- /soldering (+ baking instructions) Heating-

30、profiles of BGAs and other ICs used in Philips- sets You will find this and more technical information within the “ magazine” , chapter “ workshop news” . For additional questions please contact your local repair- helpdesk. 1- 5 Mechanical and Dismantling Instructions Dismantling Instructions The fo
