Hello, I have a problem if anyone can help me. All of a sudden my xbox 360 gives a blank screen on my hdtv. I was playing it fine 5 minutes before and turned it off. The next time I turned it back on I didn't get a picture. No error message, nothing! But on my hdtv when I load it, it loads fine with green lights and everything but I get no picture! It can't be the cable cause I just bought a brand new hd component av cable from the shop. Normally it would say HDTV 1080p across the top left, but now it says HDTV Unknown. I've tried a different cable aswell, and a different tv to see if that makes any difference but it hasn't. Does anyone know a possible solution to this?:doh::doh:
