unplug power from xbox, unplug video cable from xbox, Press and hold the xbox 'power' button on the front for a few seconds to drain any residual power from the unit. Plug the video cable back in, plug the power back on, turn the unit on from the power button, not the controller. If it still does it, try a different video cable, if trying a different video cable doesn't fix it, its possible the video is fried. Also if you can, try it on a different TV. it can, rarely, but can be a issue with the TV and not the xbox.
