My Xbox doesn't seems to like HDMI cables anymore. It used to play just fine with HDMI. Now when I try to use an HDMI cable, I get this: Warning: Spoilers inside! That's the dashboard. I've tried navigating to the display settings and changing them but no matter what setting I choose I still get a scrambled image. It still works just fine with the composite AV cable. It's a zephyr Xbox (white disc tray instead of silver) so I don't think it's an over heating issue. I haven't even used it much lately. I'm hoping it's just a handshake issue that can be fixed. I tried on a different TV to no avail as well as with a different cable. Help please?
