Blue lines on screen.

When I turn it on it is moving blue lines on the screen. When I take a picture, the light flashes and acts like I takes a picture but all it is is blue lines on the picture. The battery is fully charged. It has been a while since we used it. Is there something I am missing that I am suppose to do?

Thank you,
