I noticed on my jamb Nikon FM after fiddling around with it if I push the shutter blades up carefully with my finger on one side and my thumb on the other side using light pressure the mirror will come down. Then I can advance the film lever fully and snap the shutter. After that the same thing happens! Ugh! I hope to hear from somebody that had the same problem recently.
If not I will take mine apart in the future to see what is going on inside. Most likely something is binding the full release going back into the park position. It can be about anything I know since this camera body still looks like new showing very little use although old. Seals that rot are the main culprit in older cameras and they are installed inside in many cameras especially SLR's.I ran a little lighter fluid into the side hinged shutter blade area and received a response in the shutter to open. It stayed open as well so a CLA is due I think
