I've also go a Diax 1a which I tried to fix myself. The shutter is jammed, so I thought I'd take off the shutter from the camera as a start. I removed some screws from inside the camera which held the shutter onto the camera body. Instead of just removing the shutter, the shutter blades also fell out of the shutter mechanism at the same time. I couldn't find a way to put them all back together. This is obviously not how your supposed to remove the shutter!
