I had a similar problem several years ago with my
Gilson222 and finally contacted the company
(gilson.com). I don't remember exactly how they
isolated the problem, but I do remember I swapped
out an electronic board so that I could run the
instrument while they repaired my own board. The
cost was very reasonable and the turn-around time
was good, although having the replacement board made that a non-issue.
