I don't know what chip I've got, all i know is that it's an Evo. Everytime I turn on my Xbox the disc button goes green then it turns off for about 2 seconds. Then it turns on again and the disc button goes green again for another two seconds and then turns itself off. The third time it turns itself on the disc button goes green for about 3 seconds then flashs green and red until i turn it off. I have no idea what started it all off, at first i could just turn it off then turn it back on again and it would be ok, but now it does the same thing over and over. P.S. there is just a blank black screen the whole time.
