Subject: [disklavier] PIANO POWER OFF! (PWM OVER) on DKC100 DGH1 Mark II
Anyone have any good troubleshooting tips on this problem?
It appears to be an overtemp problem on one of the driver boards, as the problem does not happen immediately. After a disk is inserted, the piece will play for a short time, then this error message appears. You then have to power off then on, to play it again, but the error comes right back in shorter and shorter duration. Even if you stop the playback, the problem will happen, given a minute or so. Sounds like a driver circuit is overheating, even without any key solenoids being used.
Thanks for your help.
Brad
