NIKON D3100 video problem

[animike]

My Nikon d3100 video feature is not working. Whenever you record videos, it will record everything except the IMAGE IS ALL WHITE. No matter how I adjust ISO, shutter or aperture, it's still the same. It's just capturing white image.

Please help me fix this. I was hoping there's just something wrong with the configurations. Any advice will be appreciated. Thanks!
