Hello I've got OM-10 recently which is dead, in a weird way. Here are the symptoms and let's see if anyone can help: 1. The shutter fires all the time at a same (high) speed. Even in bulb! 2. The shutter fires regardless of batteries being inserted or not (that's right, no mirror lockup there). 3. Battery check and self timer don't work. 4. Light meter "works" and responds to aperture change. I tried cleaning the magnet. It's no use. I film-tested it, just in case anyone would suggest to do so. The body itself is in pristine condition. As if it's never been used. Any clues on what might be wrong? I'm well aware that I can buy a replacement for a fairly cheap price, but I wouldn't do it, owning OM-4. The whole point of this thread is curiosity. Thank you!
