I would like to ask you for help. My ROLLEI 35S doesn’t release the shutter. When I press the button it looks like it was locked. It cannot be hit. The camera was working well so far. Last photo was taken with the cable release. The lens was closed properly. Is it possible that I will be able to remove the failure by myself? Can I safely open (remove) the top of camera? What is possible reason of the damage?

Regards
