X box not coming on screen

Have you gone to you tube. I saw one time the guy wrap the x box in a blanket or something ,May have left it on, I don't know. But after a Hour or something it started to work. I hope this helped!

try this. the conductor liquid on you graphics card has porabaly come over the side and cover some of the chips around th graphics card. you need to clear the goo of (with something like nail varnish careful not to get it everywhere) and replace it. i have dont this and succesfully fixed my own xbox but it seems to have boken agn. i also saw that when i applied pressure to the biggest chip closest to the fan that helped the srcreen come back. if your screen went green before not working ever againn you have this problem. the liquid is called silver thermal compound and is use to conduct heat from a graphis card to a heat sink or cpu to a heat sink and can be bought from many computer shops.
