I took a hammer to the shutter - now it opens! Actually, I tried the suggestion and it did not correct the problem. I guess I will have to get a new camera. Very disappointed as this camera is only four years old and well cared for.
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:
Hmmm... doesn't sound too good does it? Have you tried another CF card? I know you said it doesn't work even without a card but...
Also one last thing to try is to tkae out both batteries, the main one and the slim watch style backup battery that sits right next to the main one under the cover labelled CR2016. Leave them both out for an hour and see what happens. NOTE this will probably reset your camera to factory defaults and may reset the photo numbering counter back to zero. Worth a try?
There are quite a few of us with symilar problem, but the screen is not completely black: it has some purple or pinkish color when facing light. Old pics and menu can still be viewed. I noticed 4 symilar threads on Canon A95 within the last 5 mins without any search, just looking at the top questions.
It could be that the shutter has gone out or the mirror is not going up they are only rated to last for so many shots. That is what canon told me when my 10d did the same thing. I dont remember what the repair cost was.
