What do you mean by "no still pics"? What exactly is happening? If the camera is showing a black or distorted screen when set to photo, and photos that are taken with the black screen also show up black or distorted, then this would likely be a CCD imager failure, a common occurrence for your model camera.
If so, Canon should fix this for you for free, including free shipping both ways. This is regardless of your camera's warranty status. Please check this link
