Re: [disklavier] DKC100R error message?

2014-10-17 by mangez@...

It may also be due to a fault around the key/pedal solenoids which causes the key/pedal drive supply to shut down. ( Sticky or dirty solenoid, solenoid drive transistor breaking down when it gets hot or calibration problem).

For now, I have given up on trying to make the DKC850 work with my piano, so I am back to the 100R.



But now (and this might have been a big part of the problem in trying to run the 850 through the 100R, per my Yahama dealer’s suggestion), it plays for a couple of minutes then a message appears on the display as the music stops that says:



Piano Power Off! (01:55)

(PWM OVER) _ ESBL



That is pretty much verbatim. The guy that came out from the Yamaha dealer (*NOT* a disklavier tech) said that it sounds like there is a problem in the power circuitry INSIDE THE PIANO, as opposed to inside the 100R.



Can anyone clarify or make suggestions?
