Symptoms Cannot open a tray (An opening screen is displayed on the monitor)
Diagnosis Contents
Defectiveness Assumption Points
A
Does voltage of CN9-pin 3 and 5 on the DVDM Assy change normally ? pin 3 (XCLOSE) : It is "H" level by the state that has finished doing CLOSE. Tray switch pin 5 (OPEN) : It is "H" level by the state that has finished doing OPEN. Does LOAD_DRV signal come ? BACK END IC (DVDM IC601) Is a signal output from IC351-pin 14 and 15 (CN9-pin 1 and 2) on the DVDM Assy ? FTS Driver IC (pin 15 : It is about 6V during tray opening, It is about 0V during tray closing) (DVDM IC351) (pin 14 : It is about 0V during tray opening, It is about 6V during tray closing) Are not there wire rod coming out, damage the connectors of CN9 and CN5 on the DVDM Assy ? Does voltage of CN5-pin 1 on the DVDM Assy change when pressed the inside switch ? Are the signals output from IC351-pin 9 and 10 on the DVDM Assy ? Does 650 LD emit light ? Does a pickup lens do up / down ? Does not an actuator spring bend ? Are not resin part damage, a shaft missing ? Are not there falling off of turn table, lean abnormality ? Is not flexible cable of CN7 on the DVDM Assy coming off and damaged ? Is signal output from IC301-pin 123 (FACT) on the DVDM Assy ? (Device control of around 500 mV is output usually. It is ± around 100 mV swing by focus up / down.) Connector / wire rod

Mechanism Assy Flexible cable / connector FRONT END IC (DVDM IC301)
C
Cannot playback (Spindle does not turn)
Are the signals output from IC251-pin 2 (A3), pin 4 (A2) and pin 7 (A1) on the DVDM Assy ? Spindle Driver IC It is fixed, and is not there pin 18 HIGH whethere it is fixed, and there is (DVDM IC251) not pin 23 LOW ? Are not there part falling off, alien substance adhesion in spindle motor Mechanism Assy (Spindle motor) part ? Is not flexible cable of CN7 on the DVDM Assy coming off and damaged ? Flexible cable / connector
5
Cannot playback (Playback stops)
Is signal output from IC301-pin 123 (SPDL_PDM) on the DVDM Assy ? FRONT END IC (DVDM IC301) Does not 650nm LD deteriorate ? If there is the both ends voltage of R121 on the DVDM Assy more than 650nm LD deteriorates. (Cannot playback DVD) 0.7V, 650nm LD deteriorates surely. Does not 780nm LD deteriorate ? 780nm LD deteriorates. If there is the both ends voltage of R123 on the DVDM Assy more than (Cannot playback CD) 1.2V, 780nm LD deteriorates surely. Is not there abnormality in FG waveform ? Are not there scratch and a dirt on the disc ? FG output : Spindle Driver IC (DVDM IC251) Disc Disc BACK END IC (DVDM IC601) AUDIO DAC IC (DVD IF IC1921)

Picture disturbance during playback (block noise, freeze, other) Audio is not output (Picture is normal)
Are not there scratch and a dirt on the disc ? Do not you set a disc of standard outside ? Check the waveform (BCK, LRCK, MCLK, DATA). Is signal output from IC1921-pin 7 and 8 on the DVD IF Assy ?
