Had the same problem i think, the error report/code is with av cable, but it is actually the whole system that is broken. It is basically the stage before 'the ring of death'. If its under guarentee take it back and they will replace it. If not may be worth taking it to gamestation or another games store to get more advice.

no lights but trying to find a friend that can lend a lead to try that out but his mates arn't local , will have to wait until he gets to school, thanks for the reply

I hope not will try the av lead first

thanks for your reply

we bought an second hand elite today as I expect the other 360 is knack ed so looked at a fix to the problem we had with it, find that you can fix it with Xbox 360 XCLAMP Repair Kit With HQ Paste X CLAMP 3RROD of ebay and learned how to open it with this video www.5min.com/Video/How-to-Open-U ... x-360-6557 if it works good nothing to lose
