Hi, I own a P-250 that I bought new about 17 years ago. It has worked like a charm ever since I bought it. Now however the piano is not playing any sounds when I touch the keys. It does make sounds when I playback stored songs / demos and when I run MIDI input to it. Apparently something is wrong with the keys. Does anyone have any tips as to what it could be? Or have a copy of the service manual that I could take a look at? I tried finding the service manual online, but I was only able to find the CP-300 and the P-200. And by the looks of things inside the P-255 it sits somewhere in between those two models.
I do have a some of concrete questions regarding the board itself:
Is the keybed removal procedure the same as for the CP-300?
Does the keybed bus board have that electrolytic capacitor that KSN2 circuit board has in P-200?
Is entering the TEST mode / program different than the P-200?
Thank you in advance,
