Hmm the plot thickens for my old 360. I borrowed a different power supply, rated the same 203w, now my 360 flashes 3 red lights while the power supply goes to green and back to orange. (my old power supply simply went to red when trying to turn on the 360 with no reaction from the 360)
The Microsoft site is not very helpful, hardware problem with either 360 or power supply, thanks... If power supply goes green, 360 is kaput, goes red, power supply bad, stays orange try a different power socket. I tried a few, stays orange, 360 why you no like Canadian electricity :/
Any clue? Guess I'll bring it to my local shop to get advice what to do with it.
