Ok so i got fallout 3 today and was super excited to play it just like anyone else. I got about an hour into it and then suddenly my screen turned this greenish hue. So i did what first came to mind which was to reset my xbox, so i did that unfortunately. Now when i go to turn my 360 on it turns on, i see the green lights and everything, but nothing comes up on my tv, no picture no sound.....nothing. I've tried blowing out my xbox cus i thought maybe dust was the culprit but that didnt work. I even messed around with the video cables for like an hour and that did nothing. Please someone help, im clueless as to what i should do.

to me..that is a TV issue, I had that problem with an old plasma TV, I could be wrong, if I am , I am sorry.

well damn that sounds like the worst case scenario, i paid alot of money for this tv, is there anyway to get it fixed or do i need a new tv?

just tried it on another TV, theres sound but still no picture, and yes i have it all plugged in right, perhaps its my video cables?

Well, then maybe its cables, i had an old plasma tv and something cracked and leaked fluid inside and it was toast. Does you tv work with other things...cable? DVD? etc.

Yea just tried the DvD player, works fine, im thinking its either the cables or my 360 video card is fried, thanks for the help bro much appreciated

If you have it connected via HDMI cable, then your cable is shot.
Same thing happened to me more than once.

There is a chance for whatever reason your xbox changed it's display resolution.
It doesn't sound like this is the case, but I would troubleshoot that as well.
