I have a KDS LCD monitor that goes black with a click 2 seconds after power on. I have hooked the thing up to three different sources with the same result. It doesn't power off, just goes black. It seems independant of any graphics controller problem, always Displays a screen image (source dependant) clearly before crashing, and the behavior can be repeated by powering the monitor off then on again. Backlights, displays, then fails. I dont see a reset button or pinhole on the thing such as might restore some memory setting. The monitor has been burned in for three months and operated without fail during that time. I hesitate to blame the power supply or inverter since it does power up and display - for a second or two, just like clockwork. It repeats this behavior when conected to different systems using different graphics cards and Op systems. Sound familiar to anyone?
