Well I'll cut to the chase. My friends t.v. blew a fuse and his xbox still works fine but its not working on his new t.v. but he has an hd av cable so a little light on it is red. Is it suposed to be red? My xbox has a regular cable with no hd stuff so I'm of no help, just see if the ligh on yours (asuming you have a hd av cable) is normal green or if it glows at all.
Also the little ligh is only on the cables that have hd connections and regular connection, and it some kind of slot not realy a light but its glowing red.
