Pioneer CDXP23S is an old model and has been top useful for me to find this Manual. CD Player is still repaired.
;
Inventory (Stock): a rather extensive list of service manuals, which are hard to find, especially 15+ yrs old.
Pricing: very reasonable.
Delivery/Response: Very Prompt delivery of product: Placed order and received download access within 1.5hrs.
Service Manual: a rather complete OEM service manual (15.5MB pdf file size). Scan quality was very good, accept for a few circuit board diagrams that were dark; Zooming, however, clarified the image. Has the required information for servicing the LD Player.
;
Perfect copy of a necessary document and my Sonic Modulator is repaired!
;

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 :
B
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.
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.
If the measurements show degradation of an LD, replace the 05SD Pickup Assy.
