Don't know about repair problems, but in a good order camera overexposing
(appreciable on slides only) is generally due to excessive f/ opening
(camera cannot stand a shortest time than a 1/1000 or even 1/2000 according
to recent messages). With a 100 ASA EI in sunshine it is safe to open f/5.6
or less. I did this mistake often when shooting from 25 to 64 ASA with my
100 f/2.8 lens.
The second major problem is due to flash in externals. When you use a flash
in auto mode, camera sets at 1/60 and it is very easy to overexpose. You
should use a very slow film to counteract this fact, or a very powerful
flash, closing the lens a lot. Modern srls allow an auto control of flash
in externals, but not the OMs.
