A
DVD MT PCB Assy DVD IC (IC4002)
Are the signals output from IC2301-pin 5 and pin 6 (CP2302-pin 4 and pin 5) on the DVDM Assy ? DVD MT PCB Assy Pin 5: Approx. 45V during opening tray approx. 0V during closing tray. FTS Driver IC (IC2301) Pin 4: Approx. 0V during opening tray approx. 4.5V during closing tray. Are wires of CP2302 and CP2303 on the DVDM Assy disconnected or Connector / cable damaged ? Does the voltage of CP2303-pin 5 change by pressing the Inside switch. 5 Playback impossible (no focusing) Are the signals output from IC2301-pin 9 (F+) and pin 8 (F�) on the DVDM Assy ? Does 650-nm LD emit light ? Does a pickup lens move up / down ? Does an actuator spring bend ? Are plastic parts damaged ? Or is a shaft detached ? Is the turntable detached or tilted ? Is flexible cable of CP2301 on the DVD MT Assy disconnected or damaged ? Is signal output from IC4002-pin 42 (FOSO) on the DVDM Assy ? (Device control of about 1.4 V is output usually. It is fluctuated by about ± 250 mV with focus up / down.) 6 Playback impossible (Spindle does not turn) Are the signals output from IC2301-pin 13 (MOT SPDL�), and pin 14 (MOT SPDL+) on the DVD MT Assy ? Is pin 41, 42 (STBY) fixed LOW? Is there any part detached from the spindle motor ? Or Is there any foreign object lodged in it ? Are wires of CP2303 on the DVD MT Assy disconnected or damaged ? Is signal output from IC4002-pin 37 (DMSO) on the DVDM Assy ? 7 Playback impossible (Playback stops) Does 650-nm LD deteriorate ? If the voltage at each both ends of R2303 and R2305 on the DVD MT Assy is 0.4 V or more, the 650-nm LD is definitely deteriorated. Does 780-nm LD deteriorate ? If the voltage at each both ends of R2302 and R2304 on the DVD MT Assy is 0.4 V or more, the 780-nm LD is definitely deteriorated. Are there scratches or dirt on the disc ? 8 Picture disturbance during playback (block noise, freeze, other) No sound (Picture is normal) Are there scratches or dirt on the disc ? Is there a problem with the format of the disc ?
