I have a Kurzweil Mark 110 Digital Piano, that I purchase used. It is in very good condition, but just recently the B key above middle C will not press down. It is stuck in the up position. The adjacent white and black keys are fine. So questions are:
- Is there a quick fix for this without having to take apart piano?
- I can't find the service manual for the piano (I have the owners manual but it does not describe repairs, other than 'call your local service technician'). I'm fairly handy but it is not obvious how to access the keys on the piano. It appears that the keys are attached at a point that is under the midi controls and I would have to remove the midi controls somehow. Can anyone provide guidance?
