Disklavier

Sorry about that!  I replied to the wrong problem!  My reply should have been directed to the person who had one note not playing.

For the PWM OVer message, I would look to where the Disklavier connects to the piano behind the pedal lyre.  Sometimes movers pull on this cable, OR it just looks like it is connected.  I would unscrew the fitting, pull the connector out, then put it back it in.

It could also be caused by the pedal solenoid overheating and shutting the whole system down..  That can happen because the pedal is out of adjustment.

Do a Record and Playback test and see if the note records.  Play back transposing one note to be sure.  Does the note play when a Yamaha Pianosoft disk is played?  Transpose?  Then maybe the solenoid is sticking.  When the piano action is out of the piano, pull it out, wipe it off with a dust free clean cloth and put it back.  Also check for foreign objects that fell into the piano action.
