Ok. It sounds like you have either a bad solenoid or bad solenoid driver board.


To confirm, make a recording of you loudly playing each key 10 times, going up the scale chromatically. Then play it back and see which key causes the PWM OVER message to occur. Then turn off the piano and turn it on and replay that song you recorded and see if the PWM OVER message occurs on the same key. If so, either that solenoid or the drive board it is connected to has failed.

The piano will play through 2-3 tunes and then abruptly stop and give the message. I then turn off the unit and then back on, after which it will play for a very short time.
