talking of HDMI I used it on the 40'' LCD last night and TBH the quality is better that what ive seen on blu ray. Plus it was only a £5 quid cable.E74 is covered under 3 year warranty, go ahead and book a repair. 08005871102
Also with Cardies Xbox its a HDMI and HDMI's dont show 4rrod when AV cable is unplugged.
My Xbox is a 2006 (early) model.
