The best diagram that I used in a long time. Everything was right on te money. It was easy and fast. Iwoiuld but again when I need a service manual.
;
The manual is great help for me, i'm happy to have it,thanks
 ;
Very pleased with manual except that a few more details in the drawings might make the job (not yet done, tut-tut) easier. Should be adequate though. Actually I didn't have to pay for this anyway as I was given credit for another item that wasn't quite complete. Good service, then.

Very useful manuals, somewhere graphics not very clear!

A great manual; it contained all the information I required and allowed me to restore the receiver to full working condition!

7.1.7 METHOD FOR DIAGNOSING DEGRADATION OF THE LDs ON THE PICKUP ASSY
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
A
How to diagnose
In the case mentioned above, degradation of the laser diodes (LDs) mounted on the 05SD Pickup Assy is suspected. Measure the voltage between the two ends of one of the resistors mentioned below.
No playback of a DVD :
Measure the voltage between the both ends of R322 or R325 on the DVDM Assy. If the voltage is 0.4 V or higher, the 650-nm LD is degraded. If the measurements show degradation of an LD, replace the 05SD Pickup Assy.
B
No playback of a CD :
Measure the voltage between the both ends of R321 or R326 on the DVDM Assy. If the voltage is 0.4 V or higher, the 780-nm LD is degraded.
