I have a Konica FT-1 motor SLR which has developed a shutter problem. What is happening is this:-
When I release the shutter at any speed the shutter opens, the mirror lifts and the motor winds the film on to the next frame. In order for the shutter to close and the mirror to return I have to activate the shutter button five or six times which winds the film on each time.
I know the electronics in these cameras are unreliable but can anyone point me in the direction of what the fault may be?
The camera body itself is in mint condition and if possible would like to be able to continue using it with my collection of Hexanon lenses. _________________ "I've got a Nikon camera, I like to take a photograph" - Paul Simon |

Have you looked at the three flat cables that connect the electric boards under the top cover. They seem to be the most common cause of problems. Foam insulation that is under the flat metal connector turns into gel and cause unexplained behaviour.

I haven't ventured inside the camera yet but I have seen the flickr page in your link recently. What should I use to replace the original foam insulation with? _________________ "I've got a Nikon camera, I like to take a photograph" - Paul Simon |

Things like that are usually an electrical failure, a short or a disconnect. Without a repair manual it might be very hard to find out what and where exactly. Even with it in hands it often times is not possible. |

Did you try it? I used a vinyl floor rubber noise insulation canvas (? ). I have about 20 meter roll of it and needed only 1 cm x 2 cm piece. Any thin rubber should go I think.
edit: I found it, this exactly, very good material for almost everything
