Ok, I bought an hdmi cable on Monday and hook it up to the 360 and my plasma, turn it on and the game would flash for a second like every 3-4 seconds. Ok, maybe I got a bunk cable so I find one online for cheap (new) and hook it up today , same thing.:wtf: Pretty damn sure its not my tv and my 360 is only 1.5 month old. I am clueless. Anyone?
