EOS 1n error code 4?

  1. 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?

    In your case it may be Burned out Component. Check the diagnoses and remedies.
