Case when this diagnosis is required :
When playback of any disc, including a test disc (DVD: GGV1025, CD: STD-905), won't play or doesn't play
How to diagnose
In the case mentioned above, degradation of the laser diodes (LDs) mounted on the 06SD Pickup Assy-S is suspected.
Measure the voltage between the two ends of one of the resistors mentioned below.
Measure the voltage between the both ends of R322 or R325 on the DVD MAIN
Assy. If the voltage is 0.4 V or higher, the 650-nm LD is degraded.
No playback of a DVD :
Measure the voltage between the both ends of R321 or R326 on the DVD MAIN
Assy. If the voltage is 0.4 V or higher, the 780-nm LD is degraded.
No playback of a CD :
If the measurements show degradation
of an LD, replace the 06SD Pickup
Assy-S.
