Case when this diagnosis is required :

When playback of any disc, including a test disc (DVD: GGV1025, CD: STD-905), cannot be performed

How to diagnose

In the case mentioned above, degradation of the laser diodes (LDs) mounted on the 03 SD Pickup Assy-S is suspected.
Measure the voltage between the two ends of one of the resistors mentioned below.

Measure the voltage between the two ends of R22 or R25 on the DVDM 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 two ends of R21 or R26 on the DVDM 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 03 SD Pickup
Assy-S.
