Camera won't turn on.

I have an HP Photosmart 945 camera. When I flick the switch to turn it on, most of the time it won't turn on. I can get it to turn on (if I flick the switch about 50 times), but I'd like it to turn on every time. My dad and I think it may be a circuit that's "not catching", but I don't know. When I try to turn it on the light, that turns green when it's turning on, flashes red.
