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 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 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 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 the 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. 2.1.2Laser 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: 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 Figure 2-1 Class 1 Laser Product 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. 2.2Warnings 2.2.1General All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD, symbol ). 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 kit ESD3 (small tablemat, wristband, connection box, extension cable and earth cable) 4822 310 10671. Wristband tester 4822 344 13999. Be careful during measurements in the live voltage section. The primary side of the power supply (pos. 1005), including the heatsink, 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 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 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. 2.2.2Laser The use of optical instruments 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 handling should take place as much as possible with a disc loaded inside the player.

For detailed diagnostics, check the faulting tree since no built-in diagnostic software is available in the player. 5.2.1Atapi Engine The Atapi engine is a non-repairable component. Hence, it is necessary to determine if any fault condition of the player are caused by the DVD engine before replacing it. The engine is a stand-alone system, an integrated unit of the loader and servo board, which does not need to be connected to the Mpeg board to perform it basic operation. Once a stable voltage is supplied to the engine,some mechanical movement will be observed. Hence, to determine whether the engine is faulty, remove the 40 pins flex cable and observe the mechanical movement. If no mechanical movement is observed, the engine should be faulty and it should be reconfirm with a working engine. The loader has an optical unit consisting of two lasers, one for CD with a wavelength of 780 nm, and one for, DVD with a wavelength of 650 nm. If any one type of disc (DVD or VCD / CD) cannot be identified by the player, it can be sure that the fault is due to the engine.
