Having the same problem as many other posters I have read. 9 month old 360 s 250gb Xbox froze the other day, when I turned it back on the green light became red after a few seconds and nothing came up on screen. Left it unplugged overnight, removed the hard drive, tried a different hdmi cable, nothing works. The light on my power supply is yellow when the console is off, and green when it is turned on, even while the console light is red. Do I send the xbox for service or replace the power supply?
