Re: [disklavier] DKC MarkIV : piano key 52 not working - how to adjust/repair :?

2012-10-19 by athomik

I would suspect a problem with the key/hammer sensors (most common problem) which may just be down to a bit of dirt on the lenses/shutters. There may also be some dirt in the key solenoid which stops it moving properly. You could pmail me for further advice.
