Last night my Vizio stopped receiving signal from my 622 via hdmi. Its connected directly as is my xbox.
I switched inputs at the tv and the xbox works fine in all inputs. I did the same with 622 and it doesn't work in any.
Then I reset the 622 by pulling the card and plugging back in and after the 622 booted back up the picture came and and then in a couple minutes cut off again.
Anyone ever experience this?
