eos 1n shutter doesn't fire
Hi,
I have a canon eos-1n that seems to work in all aspects except for the shutter not working. When I press the shutter release, it shows the exposure info in the viewfinder and the lens auto focuses. When I press the shutter release fully, the lens stops down, but nothing else happens. The top display panel will then flash "bc" as if an error condition exists, which I suppose is true. :-) This will stop when I press the shutter release half way again. I have replaced the battery and also tried firing the shutter without the lens and neither of these help. I also removed the battery for several days, but this made no difference (the problem did start after I replaced a dead battery that was in the camera for several months). If anyone has any ideas about anything I can do to fix this, let me know. Thanks. (respond to the group if possible. if needed my email address is dlr at cs dot pdx dot edu) Dan R. |

Yes. They basically said try a different lens, replace the battery,
maybe something else, and if those don't help, send it to us for repair. I think maybe it needs a reboot or full reset, but there is no such user function that I am aware of.

Getting to the ones in the body sucks somewhat... Other possibility is you have a deadish NiCd that will not supply the current needed for the shutter and mirror actuators, but is OK at lower loads. You can also get this with Li cells that have not been used for some time. A few cycles gets them back. What happens if you use the Battery Check button? -- Paul Repacholi 1 Crescent Rd., +61 (08) 9257-1001 Kalamunda.

Pressing the battery check button causes "bc" (non flashing) to be displayed in the top display panel along with 12 segments which I believe indicate a full battery. Dan |

In case anyone is interested, I ended up taking the camera to a local
repair place and they replaced the mirror release magnet and return spring. They also calibrated and cleaned the camera. The total repair price was $207, of which about $20 were for parts.
