EOS 1n error code 4?

Hi, Friends,

I have an EOS 1n body that is malfunctioning. I think it's

caused by me using an AF confirmation adapter that lets one

use a lens of a different mount on the EOS body. I got two

inexpensive ones from eBay. After a few attempts with them, now

the auto focus and aperture stop down don't work on any Canon

or third party lenses in EOS mount, and with a Canon lens, the

body locks with a flashing "bc" sign right after firing. With a

Sigma lens I have, the shutter fires OK, but no AF or aperture

stop down. By pressing the battery check and clear buttons

simultaneously, I get an error code of 4. What does this code

represent? Is the camera completely toast, or is there a way to

fix it that doesn't cost too much?

Thanks,

Yefei
