SOURCE: Black screen surshot camera

The camera has a recall issue, it's called a CCD sensor. Your problem is better known as the black screen of death. To date Canon is the only company that will repair this issue for free, Call Canon and they will send you a shipping label that you can print out on your computer and send them the camera and they will fix it and send it back free of charge. Canon has excellent customer support, I would never purchase any other brand of camera other than Canon because of the lack of other companies not standing behind product repair issues that are a result of poor design flaws on parts.

A stuck shutter is another common failure mode for digital cameras. The symptoms of a stuck or "sticky" shutter are very similar to CCD image sensor failure. The camera may take black pictures (for shutter stuck closed), or the pictures may be very bright and overexposed, especially when taken outdoors (for shutter stuck open).

To confirm a stuck shutter, put the camera in any mode other than "Auto", and turn the flash OFF (you don't want to blind yourself for the next step). Next look down the lens and take a picture. You should see a tiny flicker in the center of the lens as the shutter opens and closes. If no movement is seen, then you likely have a stuck shutter. If so, please see the following for further info and a simple fix that may help:
