3 Red Lights
With the help of i-fix online guide, I have manage to repair the console and it really works!
After one weeks of playing, the 3 red lights came back again! So I disable the Xbox360 fan and on the console to let the motherboard hit up by itself. After about 5 mins the console reset by itself and it turn to green light. Since then, I didnot put back the cover of the console. While I'm playing, I blow the fan direct at the open console motherboard to prevent from overhit. So far it has no problem. But I glad to get the Fix Kit from ifix rather than dump it away.
