360 was working fine when i started it up then about 10 mins into Gears 2 the colours
went all fuzzy.Took the disc out & put it back in but the same.
The dashboard colour also went funny so switched off the console & restarted it
after a while, now no picture or sound but no red lights.
PS3 & Wii work fine so not the telly, tried comp cable which gave a funny picture
then went blank, also tried other HDMI cables but still no luck...any ideas please ?
(360 is out of warranty)
