Technical Specifi cations and Connection Facilities 2.1 Safety Instructions 2.1.1 General Safety Safety regulations require that during a repair: Connect the unit to the mains via an isolation transfor

28、mer. Replace safety components, indicated by the symbol , only by components identical to the original ones. Any other component substitution (other than original type) may increase risk of fi re or electrical shock hazard. Safety regulations require that after a repair, you must return the unit in

29、its original condition. Pay, in particular, attention to the following points: Route the wires/cables correctly, and fi x them with the mounted cable clamps. Check the insulation of the mains lead for external damage. Check the electrical DC resistance between the mains plug and the secondary side:

30、1. Unplug the mains cord, and connect a wire between the two pins of the mains plug. 2. Set the mains switch to the on position (keep the mains cord unplugged!). 3. Measure the resistance value between the mains plug and the front panel, controls, and chassis bottom. 4. Repair or correct unit when t

31、he resistance measurement is less than 1 M. 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 wire between the two pins of the mains plug. 2.1.2 Laser Safety This unit employs a laser. Only qualifi ed service personne

32、l may remove the cover, or attempt to service this device (due to possible eye injury). Laser Device Unit Type : Semiconductor laser GaAlAs Wavelength : 650 nm (DVD) : 780 nm (VCD/CD) Output Power : 20 mW (DVD+RW writing) : 0.8 mW (DVD reading) : 0.3 mW (VCD/CD reading) Beam divergence : 60 degree C

33、LASS 1 LASER PRODUCT Figure 2-1 Note: Use of controls or adjustments or performance of procedure other than those specifi ed herein, may result in hazardous radiation exposure. Avoid direct exposure to beam. 2.2 Warnings 2.2.1 General All ICs and many other semiconductors are susceptible to electros

34、tatic discharges (ESD, ). Careless handling 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. Keep components and tools at this same potential. Available ESD protection equipment: Complete ki

The primary side of the power supply, including the heatsink, carries live mains voltage when you connect t

36、he player to the mains (even when the player is off!). It is possible to touch copper tracks and/ or components in this unshielded primary area, when you service the player. Service personnel must take precautions to prevent touching this area or components in this area. A lightning stroke and a str

37、ipe-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. 2.2.2 Laser The use of optical instruments with this product, will increase eye hazard. Only qualifi ed service personnel may remove the cover o

38、r attempt to service this device, due to possible eye injury. Repair handling should take place as much as possible with a disc loaded inside the player.

INDENTIFICATION: Regardless of special logo (not always indicated) One must

46、 treat all sets from 1 Jan 2005 onwards, according next rules. Example S/N: Bottom line of typeplate gives a 14-digit S/N. Digit 5&6 is the year, digit 7&8 is the week number, so in this case 1991 wk 18 So from 0501 onwards = from 1 Jan 2005 onwards Important note: In fact also products of year 2004

47、 must be treated in this way as long as you avoid mixing solder-alloys (leaded/ lead-free). So best to always 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 SA

48、C305 with order code 0622 149 00106. If lead-free solder-pate is required, please contact the manufacturer 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 400C, o To stabilize the adjusted temperature a
