It is impossible for the Shutter to be stuck, as the A40 does not have a Shutter. Sounds like you have a bad image sensor. I would contact Canon about this as they acknowledge a defective sensor in some of their models. However, depending on how old the camera is and depending on if it is one of their recognized defects, you may have to purchase a new one. Wait, what do you mean by shutter? do you mean the little covers on the front that open to exspose the lens? the little curtin like things? Tap on the front this can sometimes snap them open. If you can see the glass in the front and its still black, make sure your "display" button is not set to the off mode. Sometimes it can power on and the display will be off because it was turned off before the last time you used it. If its still black it could be a bad connection inside, wich controls the camera section inside the unit. If you bang or bump the camera ont he side will the screen flicker or show purple lines? sometimes show an image?

Black screen icons show up on screen


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, sometimes with lines, 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 this link for further info and a simple fix that may help.

However, if you made a typo, and your camera is really an SD110, the problem would then likely be a defective CCD imager. If so, Canon should fix this for you for free worldwide, and may also include free shipping both ways (free shipping varies with countries). This is regardless of your camera's warranty status.

Power shot a620. screen is not showing pictures, all icons are there but screen is black? Help please!!


Sounds like you might have accidentally pressed the DISPLAY button on the back of your camera. It turns the screen on and off to save batteries. Turn on your camera, and press this button once again to turn the screen back on.
