Our 360 was working just fine and was off for about 4 hours, then we turned it on and it had one red light (bottom right one) so I turned it off and turned it back on and it was still there. I turned it off for 10-20 mins tried again it was gone. Went to bed last night and turned it on this morning and it was back again. What does it mean and is there a way to fix it with out having to send it in? I think the error was E 74.
