Hi Zhenya,
Well, we discovered a few other problems before the repair shop. I put new batteries in, and the newly discovered action was that the camera would lockup all over the place. The shutter, would on auto, would randomnly chose a shutter speed from 30 seconds on up! On manual, it would lock up randonly also. After this incident and much consultation, it was decided it was not economical to repair. So now I am to look into another OM4 or OM4T so I can get my OM1 back from the missus
