He i have the xbox360 premium and got the 3 red lights. I tried several time the towel trick and it worked a couple times. Lately i read about the heatgun and hairdryer trick so i wanted to try it. I used the hairdryer for about 10-15 mins to heat up the memmory and GPU. It got pretty hot and slowly let it cool off. When i tried to boot it it takes about 1min 30sec to the 3 red lights. I have heated 2 more times to try it again but no result. Just black screen and 3 red lights. Is it fixable or is it totaly dead now.
