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. http://www.youtube.com/watch?v=AUE0-cPuxY8"
