I have a Canon A1 SLR that has been idled to quite some time. I now plan to dust it off the start using it again. But now, I'm not seeing anything through the view finder. It was working properly the last time I used it (about two years ago). The battery is fresh and the shutter seems to be firing ok. What could possibly be wrong with it. I have misplaced the owner's manual.
The mirror got "glued" to the up position by a sticky foam strip. Put your fingernail under the mirror and gently pull down. If it is the strip then it should pop back into position properly.
