Sounds like the invertors have died, they fire up then die.
Invertors can be likened to startup capacitors in florescent lights, when they fail, no light.

They don't have inverters. The primary capacitor may be faulty, there could be dry joints, or some other problem. You can get a PSU tester from Maplins to see which supplies are down (12V, -12V, 5V, -5V, or 3.3V)
I have never come across a TFT screen that didn't have an inverter...
Aditionally I have never experienced an inverter thank cops out after a few seconds. To date they have either worked or not worked but i am willing to accept that they can phase in and out.
I would suggest that you just boot and go into the bios and leave it like that for a while. If it is the inverter that is faulty it should still cop out if micky's suggestion is correct.
Alternatively boot with any old OS, eg win 98, ubuntu, mini xp or whatever. All you are trying to do at this point is determine if the screen still blanks out when you are not running Vista.
If, for eg, the live version of ubuntu runs ok then you will know that it is not the inverter but vista that is faulty.

Invertor is basically a starter on a flo tube, so you never saw a flo tube flicking on and off? But in this setup, high voltage they go bang!
Thanks monkeh
Just out of interest- what kind of backlighting do TFT use- is it similar to a very thin fluorescent?
