Little HDTV Help - Diagnose Problem with 22" Vizio

[EEagle]

Can anyone help me diagnose what is wrong with my tv. I have a Xbox360 hooked up to a 22" Vizio HDTV through a HDMI cable. A few days ago it started freezing with colors scrolling down the screen. I have a video that somewhat shows the problem sorry for the bad quality it's a cell phone camera.

I'd look at the Xbox360 first. They're well known for freezing.

I can use the Xbox through the component cable though.
