Sweet! I won the item on eBay and couldn't adjust the geometry or even keep a steady picure. This guide has the full schematics (not available anywhere else as far as I could tell), and was a bargain for the wealth of knowledge it contains. I hooked it up to my testing equipment, tweaked a few potentiometers and got it playing videogames in no time. Thanks!

It was just what I need to fix my old BMW's CD player. Very convenient also. Thank you.

Great Manual! It contains all the wiring schematics and mechanical exploded views that are essential for service and repair. I was surprised I even found this for such an old machine. Only wish I knew of this site many years ago.

Great manual very clear copied. You are making an incredible job. I appreciate a lot the rapidity and your efficiency. Thanks a lot

Good pdf of the service manual for this unit. Includes disassembly instructions, full schematics, board layouts, parts lists and diagnostic information. Some information is in the pdf twice (single pages, and split pages), but that could be how it was originally generated by panasonic, or perhaps the idea is to make it eaiser to put onto 8.5 x 11" pages.
Information was exactly what I needed. Delivery was overnight (less than 12 hours) and I was happy with the process.

Tone control output. Super bass input. Must be driven at a low impedance. Connected to GND. Not connected. For the connection of RCH super bass compensation capacitors. Fader input. Must be driven at a low impedance. Fader output. The front and rear sides can be attenuated independently. GND. Serial data and clock input for control. Chip enable. Data is written in the internal latch when the chip enable signal goes "L" from "H", and each analog switch is activated. Data transfer is enabled at "H". Generates a 1/2VDD power source. A capacitor must be connected between VREF and GND as a troubleshooting against power ripples. Fader output. The front and rear sides can be attenuated independently. Fader input. Must be driven at a low impedance. For the connection of LCH super bass compensation capacitors. Not connected. Connected to GND. Super bass input. Must be driven at a low impedance. Tone control output. For the connection of capacitors that compensate for bass and treble in the tone control circuit.
