okay well i have this xbox that use to get 3 red rings here and there but id unplug the power cord and plug it back in and it would turn on. it eventually got 3 red rings and wouldnt play anymore. i fix red rings so i replace the heat sinks ans everything but the fan would not run. also everytime i plugged it in to the power words and turned it on the power brick light would turn red. i think it might be the wireing to the power outlit but instead and of red rings. any advice or sugestions would be greatly appreciated.
