Antec True550 not working

[nicwat]

Hey all,
I've got an Antec True550 PSU and it has stopped working. I haven't got the invoices so i can't get it repaired by them. Does anyone know if there's anywhere else i can get it fixed or do i just have to get a new one?
It still powers up and all of the fans start spinning, i just get nothing come up on the display. If anyone has any ideas on what might be wrong i might have a go at fixing it as it's been off for well over 24hrs.
Cheers for any advice!

Get a power supply tester and check it. They are only about 10$.Sounds like some other problem though but if it is the PSU get a new one for safety and reliability.

A tester is a cheap way to test the PSU. You can also do an out of case build, starting with the basic parts and adding other parts one at a time.

Would help to list specs.

Specs are:
ASRock ConRoeXFire-eSATA2 Motherboard
Intel Core2 6400 @ 2.13Ghz
Sapphire 256mb x1950 pro
Connect 3d 256mb x1950 pro
2gb DDR2 6400
Arctic Cooling SS350ATC PSU

It is definately the power supply, i've rigged up a different one and everything works fine with that. Was just wondering if anyone had any idea on what line anything that might affect the display would be in case it may just be a busted wire or specific component that had blown. Cheers for the help though guys.
