The xbox was purchased here - http://www.hotukdeals.com/item/340325/for-sale-xbox-360-arcade-with-halo-
It failed on me this evening. No red lights just no signal detected on TV. I think it may be something to do with the graphics card as audio works. After a bit of googling it looks like the X-clamp fix may solve the problem. Microsoft won't repair it as they say the console was previously tampered with.
This console was flashed with Ixtreme 1.51 after i bought it and is not banned from Xbox live (all games were verified in abgx and on general release before playing)
I'm looking to trade this console (no cables hard drive or controller) a wireless adaptor and cash for a working unopened, unmodded hdmi console. Please let me know what you have and how much you'll be looking for on top.
Just to let everyone know I turned the console on this morning and low and behold it works. I'm guessing the fault is intermittent so would still like to trade
