My Roland electronic piano has many keys that no longer work, but many still do. Is there something I can do like take it apart and vaccume out debris or something? Or should I just give up and buy a new one?
Its possible to be a dust related problem. If you find its random keys then try cleaning out. If you see a pattern to the keys not working ie, every 8th note or similar then its a connector/electronic fault and you would need to contact a service company like ourselves Puretech Solutions.
