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!

4-3-4 To Adjust E/F Balance (PLAY mode)
1. Set TIME/DIV of the oscilloscope to 2mS. 2. Set Volt/DIV of the oscilloscope to 0.5V. 3. Ground the scope input and set to DC. and then set the DC range. 4. Connect the GND terminal of the oscilloscope to VR and (+) terminal to center to TP2. 5. Load and play the disc. 6. Turn NVR1704 counterclockwise to the minimum value. 7. Raise NVR1702 and adjust the waveform so that its middle comes to GND of the oscilloscope (or until the upper half of waveform becomes symmetrical to the bottom half, A=B) 8. Adjust NVR1704 (arrow) for normal sound.
4-3-1 To Adjust FOCUS BIAS(STOP mode)
1. Set Volt/Div of the oscilloscope to DC 100mV. 2. Ground the scope input and set the waveform to 0V, DC range. 3. Connect the GND terminal of the oscilloscope to VR, and (+) terminal to center of TP1. 4. Set NVR1701 to 0mV.
