ADC Display Fried?

I have an Apple ADC display connected to 2 x Dual 2.66 Mac Pro via an Apple ADC to DVI adapter. The display has worked as it should for a couple of years; now, all of a sudden, the display doesn't power up with my Mac. The first time I noticed this, the light in the lower right corner flickered a few times, then went dark. The screen never powered up. The display seems to be recieving power -- the light glows when I touch it -- but the display still won't power up. I've triple-checked the connections. Only the display (DVI and USB) is connected to my Mac.

Is something somewhere fried, or am I missing something? Thanks for your time.
