Roland KR-177 Random Power Off

Hi,

I’m new to this forum. I have been using a used Roland KR-177 piano for the church choir that I direct. We rehearse with it and use the disk drive recorder for the accompaniments since we can’t find an accompanist.

Lately it will randomly power off during rehearsal while I’m playing it. I am wondering if anyone can diagnose this issue. I’m wondering if it could be a bad AC power socket? I have already replaced the cord and it still will power off randomly.

Thanks for any feedback!

Ben
