Canon EOS Digital Rebel suddenly all black!?

    Howdy. I'm not a camera guy (a digital point and shoot is about my
    normal limit of semi-competence, so a digital SLR holds many mysteries
    for me), but am trying to make simple use of a Canon EOS Digital Rebel,
    model DS6041, for a project. We need to take some time-lapse photos,
    and are using this camera, hooked up to AC power, and a computer running
    Canon's Remote Capture software. I put the camera in full manual mode,
    turned off the autofocus switch on the lens, and manually focused it,
    and set the aperture and exposure with the Remote Capture software, and
    took pictures with that until I found an aperture and exposure that were
    good. I then ran a test over a weekend, one frame every 3 minutes.

    The test ran fine.

    We then set it to one frame every 2 minutes, set to do enough frames to
    cover a week, started it on a Monday, and checked it throughout the
    week. It ran like a champ. Over the weekend, however, something went
    wrong. All the images started coming out solid black. Somewhere over
    the weekend, Remote Capture crashed. I don't know if these two events
    are related.

    Anyway, the camera now only seems to shoot black images. If I power it
    down, disconnect it from the computer, power it up, and take a shot
    manually, it is black. The preview LCD comes on, showing the black
    image, for the 4 seconds or so that it normally shows a preview, and the
    image gets written to the CF card (since I'm not hooked to the
    computer). I can go into the "review images on the card" mode and see
    my black images there.

    Basically, everything seems normal. Except the images are now coming
    out black. There's no error messages.

    I did the "reset all camera settings" command to make sure that someone
    hadn't fiddled with the camera and put it in a weird mode. Still all
    black. Doesn't matter if it is in manual mode, or one of the automatic
    modes, or if it is using flash or not. All black.

    The building air conditioning is off on the weekend, but we had a record
    cold weekend. 30 degrees F colder than the previous weekend (the one
    when I ran the successful test). So, I don't think there is much chance
    that the camera overheated and damaged itself.

    Anyone have any ideas as to what might be wrong here?

    Sounds like the shutter failed. Not unusual with that brand. Also,
    for something unatended like this, I'd make sure the whole thing was
    connected to a UPS of some kind.

    Another possibility is that the mirror is stuck down. You should be able to
    test for that by setting a slow shutter speed and watching to see if the
    viewfinder goes dark when you fire the shutter.

    BTW, ignore the "Not unusual with that brand," which is absurd. Rich is a
    ritual Canon basher, and his editorial pronouncements on such matters aren't
    worth a crap.

    That doesn't sound good. The auto modes should be fairly fool-proof.
    Sounds like a hardware failure ... especially given that a Rebel/300D is
    going to be several years old and...
    .... cold is just as harmful as heat.
    It's dead, Tim.

    Haven't heard of that with EOS, but both my IXUS 70 and S2IS
    stopped taking photos and just produced all black. The
    preview on the screen was all black too, so I figured it had
    to be the sensor. Both of them, when they were sent to Canon
    for repair came back with "No Fault Found", and have both
    worked perfectly since they came back (about a year for the
    S2, about 3 months for the Ixus).
    Try firing the camera without lens to see if both the
    shutter and mirror are moving and you can see the sensor. If
    so, then it sounds like your sensor has died. I'm sure if
    you send it off to Canon for a warranty repair, it will come
    back "No Fault Found" and work perfectly.

    Canon is infamous for poor QC. A little homework before making your choice
    would have steered you toward a more reliable brand.

  9. It would be interesting to know how many pictures that camera has made over
    its life.

    Sounds like for the sessions being talked about between 4500 and 5500 photo's
    were taken. While this may number of photos is not be all that many for a
    new camera if this camera has been used in this fashion a number of times it
    could have a large number of exposures on the shutter and mirror.

    Yoshi is a well known Mario character. A little homework
    will show it doesn't know a camera from a turtle.

    If you shipped it without battery it probably cleared all the memory and did
    a factory boot. Try leaving the battery out for a few days and see if it
    cleares it. It has worked for me a couple times on digital camera hangs.

    Thanks for the info. It does seem to be the shutter. I can take the
    lens off and invoke the sensor cleaning function, which is supposed to
    flip the mirror up and open the shutter, to allow the sensor to be
    cleaned, and see the shutter is not open.

    It is not totally gone. It will occasionally take one or two pictures
    (and when it is in this brief happy mood, I also see the sensor when I
    try sensor cleaning mode), and then it goes back to the shutter being
    stuck.

    As for why I picked this camera, another department at work already had
    it. It was the cheapest camera they had (and so the easiest to get them
    to part with) for which I was able to find free software for time lapse
    photography. :)
