Replaced Xbox PSU, and...

[Gurlugon]

...now it powers on, but I get a blank screen. The fans and disc drive work fine, and when I eject the drive tray, the boot up image appears and freezes and I hear a repeated clicking sound from the TV's speakers. Won't play any games.

Fuck. Anyone know what I should do? What it might sound like?

What did you replace it with? Another Xbox psu I hope? It should have the exact same rating, because I don't think the xbox psu was ever revised. What a strange problem.
