Stuck Key - Kurzweil K2500

[Kurzweil88]

Hey everyone.

I have a Kurzweil K2500XS and the middle B key is very sluggish and sometimes won't come up at all without pulling on it. Does anyone know how to fix this or at least get me pointed in the right direction? Thanks a bunch.

I once had problems with one key. I don't remember exactly what the problem was, other than the key being impossible to play properly on.

When I turned the K2500 upside-down to open it in order to try to investigate the error, the problem fixed itself. The issue was probably caused by one of the weighted hammers being off position or something like that, and turning upside down caused it to fall into it's original position again.

This only applies if you have weighted hammer keys, though, I think only the k2500X S has this.

Odd soloution but I'll give it a try. I do have the fully weighted K2500xs so we will see. Thanks!
