not sure about the srt200, but the 101 had adjustable shutters and meters on the bottom of the camera once the case was off. never adjusted them myself, but i got xg-ms back to factor specs on the shutter speeds and new caps. (lot of soldering on thin old boards, arrg.)
i was gearing up the adjust the light meters, but never did.
unless you very comftable with soldering, and small mechanical parts, send it off to some one who knows.
just my .02
