Bruce... do you want to handle this one?  ;-)

(Bruce Wahler, a member of this list, has done much more work on synths than
me.)

But I'll tell you what I know anyway.
It's hard.  Really hard to fix keyboard mechanisms.  They're hard to get to
inside the unit, therefore you usually have to pull out the whole key
assembly sub-chassis.  Then the method each manufacturer uses to detect the
key press differs... but usually it's via membrane switches - the same kind
of thing as on your cell phone.  Not very sturdy, and not easy to repair
once the membrane or rubber or whatever gets bad.

That's the bad part.  The good part is that if the membrane stuff is still
good then the problem is likely that the pressure pads need cleaning.  But
that's still bad because it usually involves removing each key seperately to
be able to get to the part that needs cleaning.
