First of all,

Let me introduce FrankenPuter

Obviously, its a work in progress.

Anyway, the 14" lcd I am using has a burnt out power brick.. The brick (before it died) put out +5 @ 2.5amps and +12 at 2.5 amps.. Right now, I have the LCD hooked to an ATX power supply, but it is rather cumbersome and rather annoying. Unfortunatly, the power supply running the computer is a rather limp 235w mini atx.. It will power the monitor, though the monitor will start flickering after about 5 mins of use...

the point of this post is, I would like to find a way of running this LCD off of a rather beefy 12v power supply, or a better solution than what I am using.

If the LCD is the only thing running off the 235 watt PSU, my guess is that the 12 volt output is not regulating properly because you have no load (or a too small load) on the 5 volt output. Try putting a 2 to 5 ohm load resistor on the 5 volt output.

Better yet, does the PSU in your PC have enough reserve capacity to power itself and the LCD too?
 
The LCD works great off of the ATX supply I have it wired to,

Unfortunatly, the crappy power supply in the pc itself doesnt seem to be up to the task of running the LCD as well.
 
There are smaller TFX12V power supplies you can also use which will give you plenty of power--there's an In-Win 240W PSU at the egg that's nice and small and doesn't cost much. I guess I'm not quite sure what you're looking for, though.

It is possible to use the 12V power supply--you'd have to get a DC-DC convertor or some other sort of regulator to step it down to 5V, but if the 12V power supply has the grunt, you can use it.
