First make sure you are taking pictures in auto, and not in manual (make sure the mode selector dial is not on the little red camera with an M). If it's not...

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:

Now the A430 is not capable of taking 15 second exposures as recommended for the fix. Instead try setting the camera to manual mode, turn off the flash, got to a darkened room, and take a picture. Open the battery door while the red and yellow light are flashing. Repeat as the fix recommends, but please note that there may be only a small hope that this will work as the shutter may be stuck in the open position. This is harder to get unstuck than a closed shutter.

If the above doesn't work, consider attempting Fix 5a listed on the web page. There is some risk of damaging your camera with this fix, that's why I hesitate to recommend it until last.
