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 SafetyThis 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 UnitType: Semiconductor laser GaAlAsWavelength: 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 degreeFigure 2-1 Class 1 Laser ProductNote: 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.2.2Warnings2.2.1GeneralAll 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.2.2.2LaserThe 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.Text below is placed inside the unit, on the laser cover shield:Figure 2-2 Warning text2.2.3NotesDolbyManufactered under licence from Dolby Laboratories. “Dolby”, “Pro Logic” and the double-D symbol are trademarks of Dolby Laboratories.

The schematic provided in the manual is only for information and no service parts will be available.4.3.2DVD ModuleThis module can be repaired as follows:1.The VAL6011/14 is a combination of loading mechanism and DVD-mechanism. Both are not repairable units and in case of failure, it has to be replaced with a new loader VAL6011/14.Note: When replacing with a new VAL6011/14, two solder joints have to be removed after connecting the OPU flex foil to the mono board.The solder joints, which shortcircuits the laser diodes to ground, are for protection against ESD. Refer to figures 2-5 and 2-6 for location of solder joints.2.The mono board has to be repaired down to component level. Repair handling of the monoboard requires a workshop with sophisticated desoldering tools.Figure 4-3 Solder jointsFigure 4-4 Solder joints4.3.3ComPairFor assistance with the repair process of the monoboard an electronic fault finding guidance has been developed. This program is called ComPair.This ComPair program is available on CDROM.The version of the CDROM for repair of the monoboard is V1.3 or higher and can be ordered with codenumber 4822 727 21637. This is an update CDROM, so when the ComPair CDROM is used for the first time, one has to install the ComPair Engine CDROM V1.2 first.The V1.2 CDROM can be ordered with code number 4822 727 21634 and has to registered after instalation. The procedure for registration is explained in the help file of the program and in the CDROM booklet.The cable to connect the monoboard with a PC can be ordered with codenumber: 3122 785 90017.All the hardware and software requirements of the systems, necessary for working with ComPair, are described on the CDROM.4.3.4Service PositionsRefer to dismantling instructions for dismounting of the board.Figures 2-7 to 2-8 shows the service position that are recommended during repair of the boards.Figure 4-5 DVD963SA LayoutFigure 4-6 DVD963SA service manualDiagnostic Software, Trouble Shooting and Test InstructionsEN 21DVD963SA5.5.Diagnostic Software, Trouble Shooting and Test Instructions5.1Dealerscript5.1.1Purpose of Dealer ScriptThe dealer script can give a diagnosis on a standalone DVD player, no other equipment is needed to perform a number of hardware tests to check if the DVD player is faulty. The diagnosis is simply a error or pass message. No indication is given of faulty hardware modules. Only tests within the scope of the diagnostic software will be executed hence only faults within this scope can be detected.5.1.2Contents of Dealer ScriptThe dealer script executes all diagnostic nuclei that do not need any user interaction and are meaningful on a standalone DVD player.The nuclei called in the dealer script are the following (the number after each nucleus name corresponds with the number being on the local display when the nucleus is executed during the dealer script):NucleusFigure 5-1 Dealer script nucleiFigure 5-2 Dealer ScriptDisplayNucleusNucleusDescriptionCountdownNumberName7 6 PapChksFl Calculate and verify checksum of FLASH memory6 12 PapI2cDispChecks the I2C interface with the slave processor on the display board5 13 PapS2bEcho Checks the I2C interface to the basic engine4 11 PapI2cNvram Checks the I2C interface with the NVRAM3 15 PapNvramWrR Pattern test of all locations in the NVRAM216CompSdramWrRPattern test of all locations
