I purchased a replacement power supply on Ebay, the PS was an after market model that can be switched from 120v to 220v. When I got it it looked really cheap but it did work. I used it quite a while but I had it connected to a HDTV and the picture was perfect. I sold the Xbox to a friend and soon he was complaining about the picture, I took it home and still it looked perfect until I connected to a composite video out and indeed the picture sucked. Well after checking everything I got a original PS and now it's perfect picture. I guess my point in posting this is so anyone else looking for a replacement PS would be better to look at an OEM unit rather than a knock off unit sold on Ebay.
