This video will show you how to fix an Xbox 360 Power Supply. I bought my Xbox 360 Slim a little over a year ago and it's already malfunctioning. The fan stops working and shuts down my xbox. The green light on the power supply turns red and it shuts down. I contacted customer support and since I'm out of my 1 year warranty, they would have to charge me $35 + shipping to send me a replacement power supply. I figure, might as well try to fix the one I have so that's what I did. It did fix the problem of my xbox shutting off after a short period, but unfortunately, it's still making a bit of noise. Better than nothing though.
