In case problems remain, the customeris requested to contact the workshop directly. The lens cleaning (method 3) should be mentioned in theaddendum sheet.The final wording in national language as well as the printingis under responsibility of the Regional Service Organizations.4LIQUID LENS CLEANINGBecause the material of the lens is synthetic and coatedwith a special anti-reflectivity layer, cleaning must be donewith a non-aggressive cleaning fluid. It is advised to use“Cleaning Solvent The actuator is a very precise mechanical component andmay not be damaged in order to guarantee its full function.Clean the lens gently (dont press too hard) with a soft andclean cotton bud moistened with the special lens cleaner.The direction of cleaning must be in the way as indicated inthe picture below.Before touching the lens it is advised to clean thesurface of the lens by blowing clean air over it.This to avoid that little particles make scratches onthe lens.INSTRUCTIONS ON CD PLAYABILITY2 - 2BLOCK DIAGRAM3-1 3-1CD SERVO BU9543MCUBX8804128pin QFPINPUTRC5/RC6 CODELCDET8862Q& KEY PARTTDA8922CTHMAIN L/RINPUTRCSENSOR16M SDRAM8M SERIAL FALSH EN25T80PICK UPMOTORADC WM87823CDCDRIVER ICTDA7073AMUX74LVC157AUXTUNERSI4730 OR TUENRPACK MICRO PHONEUSB/SDMOTOR DRIVER BA5826IICMUL-L/RIICPCM,DATE PCMCD L/RTUNER L/RCONTROL DATACD PCM BCK,LRCK,DATETDA8920CTHFRFUNCTION IC TDA7468D3CD LOADERTDA8922CTHSUBFLFHRFHL2 X 50W2 X 50WMP3 LINEINPUTAMP3CDCPICK UPMOTORTUNERSI4730 OR TUENRPACK MICRO PHONE3CD LOADERSUBFLFHRFHL2*50W2*50W1*200WMP3LINEAMP BOARD3CDC8P/120MMCN903 TO CON3018P/150MMCN611 TO CON302FR6P/120MMCN602 TOCON5215P/150MMCN607 TO CW10510P/120MM（AB）CN607 TO CW10518P/130MM（AA）CN603 TO CW1015P 150/330MM（3+2P）CN904 TO CN609/CN6124P/150MMCN903 TO J63CDC KEY4P/150MMCN912 TO CN9134P/220MM（AA）CN906 TO CN907USB4P/220MMCW104 TO CN90416P/170MM（AA）CN501 TO CD RF6P/200MMCN505 TO CD MOTOR5P/200MM（AA）CN504 TO CON23CDOPEN/CLOSE2P/200MMCN551 TO CON128P/80MM(AA)CW101 TO CON589MICRO PHONEMAIN BOARDKEY BOARDMCU BOARDUSB BOARDCD BOARD14P/180MM（AB）CN901 TOCW1POWER SUPPLYAC CORD6F(BLACK)WIRING DIAGRAM4-1 4-1DISMANTLING INSTRUCTIONS1) Loosen 4 screws to remove the Cover Top of the set.2) Loosen 3 screws to remove the Panel Left and 3 screws toremove the Panel Right of the set.3) Slide out the CDC Tray as shown in the diagram below withthe help of a flat head screw driver.Dismantling of the CDC Module and Front PanelRemove CDC Module4) Remove the Cover Tray CDC as indicated.Sliding Out The CDC TrayFront View CDCRemove Cover Tray CDC5) Loosen 2 screws A and 2 screws B to remove the CDCModule as indicated.6) Remove 2 screws at the bottom to separate theFront Panel Assembly from the Plate Bottom.BB5-1 5-1Dismantling of Rear PortionDismantling of the PCB Board1)Remove 3 screws C as indicated to loosen the Tuner Board.3)Remove 4 screws E and 4 screws I as indicated to loosen the Amp Board.4)Remove 3 screws F as indicated to loosen the Bottom Cabinet.5)Remove 4 screws G as indicated to loosen the fan.2)Remove 5 screws D and 4 screws J as indicated to loosen the Main Board.2)Remove 2 screws M as indicated to loosen the USB Board.1)Remove 27 screws K&L as indicated to loosen the KEY1&2 Board.CFD EIJKL MG5-2 5-2
