Hello everyone. I recently got an xbox 360 (falcon o.o) and decided to go for high def so i purchased an hdmi cable. I thought the cable was corrupted or something cause it wouldn't give any sound and it would flash with a black screen every 30 seconds or so. I went to the shop and exchanged it to a deffirent one, and now it doesn't work at all, but the problem is not in the cable cause i tried connecting my laptop and it went without any bumps. So I'm pretty sure the problem is in my xbox's hdmi port. Any ways to check that? Whenever I connect the hdmi cable no lights flash on the ring of light (dunno if it's supposed to flash though). Oh and if theres something wrong with my port how do I open up xbox's case?
thanks a lot for your replies.
