I had similar sounding symptoms on my brought-back-from-the-dead Canon A-1. Out of several shutter releases, the winder wouldn't move and the viewfinder turned dark in a few of them. It turns out that the reflex mirror was getting stuck at the up position. I could force it down (using the clip of a ball point pen cap to pry the mirror away from the up position), and the mirror appeared to then retract to its normal position and the camera would function again, until the mirror locked up again. The solution in my case was a touch of a lubricant oil to the hinge of the mirror driving arm on the side of the aperture box. In A-1, while looking from the front, the hinge is on the left side wall. The camera has been working flawlessly ever since. This may not be the exact problem in your case, but it is worth checking. |
