The screen is black with the power button on. If I turn the monitor power button off, then on again, I will get a picture for about 5 seconds before it goes black again. I have also tried rebotting the computer and I momentarily get a picture before it goes black again.
Any ideas or comments would be greatly appreciated. Thanks.
Plug in a different monitor temporarily, check your display settings (right click background, settings, advanced, monitor)
and set refresh rate to 60hz.
plug in this monitor again and see if that helps
some monitors (lcd's especially) cannot handle beyond 60hz

I believe the power led button is still on while the screen goes black, if yes, it means the picture board of your monitor is bad that is why it appears for a second and goes black after that

Yes, It sounds like the backlight inverter circuit is shutting down. No inverter power, no backlight. On some monitors the inverter circuit will shot circuit the power power supply which makes the power light flash on some it just kills the backlight. You can usually check with a flashlight. Hold the flashlight pointed at the screen and see if you can see any of the icons or background picture. If you can then it is the backlight circuit or backlight tubes, usually the circuit.
Same problem - unplug both computer and monitor - hold power button for monitor for 15-30 seconds...then power it back on and then power on the computer. Seems from other sites there is a power issue with the monitor - this worked for me.
Try shining a flashlight on the screen, or without the flashlight, try to see if you can distinguish anything on the screen at all, if you do, the backlight is dead, or the monitor has an internal most likely unfixable problem.
