If you have already ruled out the possibility of your TV problem then I guess the problem is at your Xbox 360 HDMI port, might be faulty already.

There is a few things you can check before you declare the HDMI port dead, check for any dust in the HDMI slot, remove your HDD/USB drive boot up without them.

If none of this help then its too bad, you have to buy a Component Cable (1080i capable) or Send for Warranty
