Xbox 360 Help

[farley91]

I need help with my 360. About 2 weeks ago it was working fine, but 4 days ago I turn it on to play some GH3, but I get nothing. Everything starts up fine, no RROD or anything. However when I switch my HDTV to COMP it says I get no signal. I have checked all of the cables twice and none of them were loose or anything.

Does anyone have any idea what is wrong with my 360? Also, yes I have checked that my cables are plugged in the right places.

I can only think that maybe my component cables went bad. If anyone could help me out here it would be greatly appreciated.

EDIT: Also I have made sure the component cable is switched to the HDTV on the cable.

Your display settings might be set to the wrong resolution when in HD mode .
See if you can check it in SD mode and see what it says it's set at .

Okay I tried switching it to composite, but no luck there either. I still get no screen at all, just the blue on that says no signal on my HDTV. Anyone else out there care to try and help me resolve this problem?
