Diagnosis Contents
• While a tray rotates, is a signal output from CN124-pin 5 (TRAY
POS) on the DVDM Assy ? (Is a signal fluctuating in the range of 0-3V
?)
• While a tray rotates, is a signal outputting from CN124-pin 4 (DISC
SENS) on the DVDM Assy ? (Is a signal fluctuating in the range of
0-3V ?)
Are the signals output from IC101-pin 34 (F_DRV) and pin 35
(F_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 CN121 on the DVDM Assy disconnected or
damaged ?
Is signal output from IC301-pin 33 (FACT) on the DVDM Assy ?
(Device control of about 2.6 V is output usually. It is fluctuated by about
± 100 mV with focus up / down.)
Are the signals output from IC101-pin 12 (A3), pin 13 (A2) and pin 14
(A1) on the DVDM Assy ?
Is pin 41 fixed LOW and is pin 38 fixed HIGH ?
Is there any part detached from the spindle motor?
Or Is there any foreign object lodged in it?
Are wires of CN122 (DVDM Assy) and CN3 (SSIB Assy) disconnected
or damaged ?
Is signal output from IC301-pin 44 (SPDL_PDM) on the DVDM Assy ?
Does 650-nm LD deteriorate ?
If the voltage at both ends of R201 on the DVDM Assy is 0.7 V or more,
the 650-nm LD is definitely deteriorated.
Does 780-nm LD deteriorate ?
If the voltage at both ends of R211 on the DVDM Assy is 1.5 V or more,
the 780-nm LD is definitely deteriorated.
Is there abnormality in FG waveform ?
Are there scratches or dirt on the disc ?
Are there scratches or dirt on the disc ?
Is there a problem with the format of the disc?
Is signal output from DOUT signal (CN911-pin 21) on the DVDM Assy ? DVDM CN911-pin 21
