I have a Konica FT-1 which a shutter that will not allow a picture to be taken. When I put film in, the film advances. It use to work ans suddenly stopped after being stored for several months with the batteries out. I believe it was stored with the switch on.
Some added information: The LED indicator does not seem to be working correctly either. Even when in AE mode, the LED is usually at the M mark and no other location is illuminated. When it is off the M mark, the location does not seem to correspond to the correct aperture for the available lighting. If you press the shutter, the LED disappears and sometimes it does not come back very quickly
