Question about Pentax Program Plus 35mm SLR Camera
One old camera. You have an electronic shutter and mechanical (backup) so you may have a dead electronic shutter. I would check the battery and contacts. If they are good... the shutter is bad. You have a standard K-mount body, any lenes will fit any Pentax camera, film or digital. The lenses will go on more modern Pentax bodies but will not auto-focus if on an AF body. These bodies are some 25+ years old, many places are selling them for $30 or so.. there are just thousands out there. If you want to stick with film, go for a newer AF body and you can still manually focus.

There is an arm in the seiko shutter assembly used in this camera which selects auto, 1/125, and 'B' modes. It's a purely mechanical thing.
Something may (HAS!) have got into the shutter works and jammed it in this mode. You will have to open it up to see what this is.
It is quite likely that the offending something, is one of the synthetic rubber bumpers fitted to make the mirror a little quieter, or perhaps the spring that locks the winder into it's 'home' position has broken. The bumpers are all breaking now, and need to be removed. The springs break in some due to fatigue. (Not all though. The metal seems to be very variable in quality for this part.)
To see how to open the camera up for repair and how to do this properly there is a camera repair site which deal with this and other cameras in detail. alternatively you can contact the author who can offer a very competitive camera repair service for these models.
