I just bought a new camera a few months ago, it's a Canon SD870IS. It worked well up until now. I've taken about 1000 pictures with it. Today when I tried to scroll through the pictures I've taken on the camera screen, they came up as just a swirl of colour. If I turn it off and back on again, sometimes the pictures come back normally, but not every time. Even when they come back, after about 10 pictures the colour swirl just comes up again. I don't think it's the memory card because if it was corrupted the pictures probably wouldn't come back ever. Also, I can download them and they seem to be fine. I just can't view them on the camera screen. Does anybody know why this would happen or how to fix it?
