![]() “AUTO… curtain is kept open” looks like our problem, and “ASA contact defective” seems worth checking. There’s a 238-page service manual available for these cameras (thank you Benoît Suaudeau) and it has an electrical troubleshooting section starting at page 174 that says: I had a friend clean the circuits and it worked a treat after that.” No more details there, but a poor electrical contact sounds promising. The first hint I found online was here, in a post from 2003 by “rokkor fan” who writes: “I had this once on a XG-1, and it was as a result of the mirror slap jarring the circuitry under the shutter release. I was keen to fix it, especially as these cameras are designed so that the light meter only works when in Auto mode. When stuck open, it often let in enough light to ruin both the previous and following photos as well as the current one. It worked well, except that the shutter would sometimes stick open when fired in Auto mode, and the only way to close it was to switch out of Auto. It was made in 1980 or so, but I bought it in 2018. The camera is one that I wrote a happy post about last year (“ A film camera“). This was my first attempt at repairing a camera and my first experience of 3D modelling and printing, so it was certainly interesting to me. If that sounds in any way interesting, read on. The replacement part is good enough to use, but could probably have been better I’ve published the model for it, and would appreciate any ideas.I modelled a replacement part using 3D modelling software, had it 3D printed, and replaced the part in the camera. ![]() ![]()
