my girlfriends MZ-7 started misbehaving last weekend. it'll be fine for a few frames, then the mirror will remain up after the shutter has closed. the film doesn't advance... the whole things just jams up. the mirror can be pushed down again by hand, but just flips back up. once the mirror is in this position, the camera is totally unresponsive. if the batteries are left in the camera while the mirror is 'up', something gets very very hot inside the body, including the batteries. the only way to get the mirror down again is to leave the camera for the best part of a day with no batteries in. after this, once the batteries are replaced, the mirror pops back down, the film advances and it's all back to normal, but only for a few more frames before it all starts happening again.
