I have a Dell E193FP 19" Flat Screen.
I turned my computer on this morning and the Green power light came on, but the screen went blank. When I try to turn it off/on it blinks the picture for s split second, the goes blank again. I have un-plugged and re-plugged the entire system, with no luck. Still just flashes a picture for a split second and then goes blank. Any ideas?
Unplug the cable from your PC, if the monitor shows a test image, the monitor is fine and the problem is with your graphic card.
If you dont see nothing on-screen after unpluging the cable from the PC, then the monitor in damaged. Send it to repair.

Seems to be a very common problem with this screen. Im taking one apart as we speak to try to discover the problem. In the mean time - check that the Power Input isnt loose, and you can wiggle it around. Usually means the power is arcing onto the board
The backlight or inverter may be bad. With the monitor on and the room dark, hold a flashlight very close and shine it on the screen . If you can see the normal display the monitor is OK but the backlight or the inverter which provides proper voltage to the backlight has gone bad.
i had same problem, fault was traced using a multimeter set to diode measurement, i found that one of the high power switch transistors in the inverter side of the power board was short circuit (there are four in the same area sticking up from the board, not surface mounted). normally they should measure 450 ish but when they read 0-010 its gone, pulled it out of circuit and remeasured it, gone, replaced and fixed.
