Power Cord Problem?

[jarcini]

Hi, I need help debugging an apparent problem with the power cord of my XBox 360. I recently moved to the UK from the US and brought along my box, knowing of course that I can only play US games. Since the output of the power supplies of both UK and US version is the same (or seems to frothe specs) and they only differ in the required input (220 vs 110), I decided to buy a UK power supply unit in order to avoid having to deal with an step-down transformer. What I DID NOT change was the power cord thinking (perhaps erroneously) that a power cord is a power cord and both UK and US version would be the same. Now to my problem: after connecting everything, my XBox doesn't power on ... After my own checking, I discovered that my original US the power cord doesn't seem to be working. So my question is: is there a fuse or something like that that would have tripped the moment that I plugged the US cord to the 220 volt UK outlet? Do I need a special type of power cord? If so, does anyone know where to find those?
Any help would be very much appreciated.
