Betreff: [sdiy] Need service manual for CASIO PX-410R (PX-575R)

Hi all,

I mostly have luck finding service manuals for all the keyboards I service
but this one is hard to find.. CASIO PX-410R (PX-575R)
Only User Manuals available..
Anybody have a clue where to find one ??

The problem I need to fix is.. NO SOUND at all.
No sound on the internal speakers
No sound at the headphone jacks
No signal at both Volume pot L+R pins
If I feed a small signal at the MIC input I can hear it (with some reverb in
it.. ??)
In the internal speakers on both L+R sides.
If I touch the Volume pot output pins with
A small screwdriver I can hear noise coming out of each of
the internal power amp speakers.
So the stereo audio chain is working OK.

It seems to be a digital sound board problem.
I checked some of the flat cables wires and I could see
Power voltages (+15v, +5v, +3.3v) .. but that’s it.

I need the service manual to go further..

Anybody have a PDF link??
