Dell 2007WFP Problem

[foodfightr]

I have two 2007WFP monitors which have been great thus far. All of a sudden one of them won't stay on. When I power on the monitor it shows the screen perfectly for a split second. Then the display goes black. The power button stays lit up green and the computer behaves as if two monitors are connected. Pretty sure it's no longer under warranty and I'd hate to throw something out with a perfect screen, especially since I have another matching unit. Any ideas? I've tried testing on different inputs already. No luck.
