About a year ago, I responded to a local ad selling a lens. After I paid for the lens and about to leave, the seller asked me if I wanted a broken Program Plus. Of course I did. She gave me a Program Plus body with the "stuck up" mirror, telling me that it had been like that for a year.
I took it. On the way home when stopping at a red light, I couldn't resist and played with the camera. When I pushed the shutter release and gently lifted the mirror at the same time, the shutter tripped and the mirror went down.
The camera was OK ever since.
Later, I accidentally created the same symptom by advancing the film just slightly before the shutter finished its action. The cure is the same: pushing the shutter release and gently lifting the mirror at the same time.
