Are the signals output from IC101-pin 3 (FOCS_DRV) and pin 4
(FOCS_RTN) 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 CN101 on the DVDM Assy disconnected or
damaged ?
Is signal output from IC201-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.)
Are the signals output from IC101-pin 30 (W), pin 33 (V) and pin 35 (U)
on the DVDM Assy ?
Is pin 26 (STBY) fixed LOW ? (pin 26 is High at playback: 3V)
Is there any part detached from the spindle motor ?
Or Is there any foreign object lodged in it ?
Are wires of CN102 on the DVDM Assy disconnected or damaged ?
Is signal output from IC201-pin 37 (DMSO) on the DVDM Assy ?
Does 650-nm LD deteriorate ?
If the voltage at each both ends of R322 and R325 on the DVDM 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 R321 and R326 on the DVDM Assy
is 0.4 V or more, the 780-nm LD is definitely deteriorated.
