I have two keys on my disklavier that are not striking the strings correctly. Most of the time they just make no sound when struck like it's not hitting the string, but occasionally still work correctly. Is there something I can adjust myself? Can someone tell me what I should look for and if I can fix it easily? This is on an upright MX-100A. Thanks for your advice.
