"Magnets -- why is it always magnets...."

No, the PC doesn't have a "reset" position.

The PC has 3 electromagnets -- one to control the exposure time, one to
control the aperture arm in program mode, and one to release the first
curtain.  Any of them can get "sticky" -- sounds to me like the last
one, the first curtain release magnet, is sticky.

The only long-term reliable solution is to have the camera disassembled
and get this magnet assembly cleaned -- a full overhaul, of course.  But
you _might_ get it to break loose for a while by smacking the camera
firmly against the palm of your hand.  (Now, now, now -- it's a sturdy
beast, a firm >>whack<< or two (or ten!) won't hurt it!  Just don't
leave a lens on it when you do!)

If this _does_ release the mirror, make a habit of _not_ winding the
camera until just before you want to take a shot (off the top of my
head, I don't recall for sure if leaving the camera un-wound keeps this
magnet/armature separate, but it might).  That is, until you've had the
camera overhauled -- then don't bother, it's extremely rare to see this
happen twice on the same camera.
