i flick the switch on, its red as normal press the sensor goes green for about 2 secs, then yellow for .5 of a second then flashing red then normal stand by red, it wont even let me take out my cod disk.
cant be over heated, i only switched it on for 5 mins before it went...
thats the yellow light of death.
hard drive is fuxored (i think) and theres nothing you can do about it.
phone sony, they will give you a free replacement, but it will take around 6 weeks to get your game back, and there is a shortage of 60gb consoles at the moment so that could take some time too
