Check to see if the image is Dimmed. Chances are the power supply on the FPD is either dead or not supplying power to the back lights.

Your problem is the back lights are not being powered. There is a signal going to your FPD because the power light remains on green, but the back lights are what helps support an image from the Front Panel Display.
The only way to fix this is to open it up.

If its got 3 boards inside((logic-->video, Inverter, Power)) The problem is the Inverter. Replace it.
The inverter is the board that supplies power for the backlights to turn on. The backlights
provide a light.for the LCD Panel(provides color and is the logic. ... similar to a projector.
If its got 2 boards inside ((Logic-->video, Power)) The problem is the power supply. The inverter is embedded onto it.

Simply replace the part with a known good one, and you got a spanking new monitor.

The red light is the indicator for the HDD activity , since it stop it's clear that the corrupted files were essential ones, that should have been loaded during the Windows boot process.
Your only thing left to do is to reinstall. If you're lucky you can get away with a Repair install, try it first.

Monitor displays breifly then goes to blank screen


If tried the monitor on two other computers with the same result -- definitly your monitor is faulty. Take it to the repair shop. To make double sure, run your computer with another monitor. If everything is fine now; you can blame the monitor.

LCD monitor comes on for 1-2 seconds and then screen goes dark (power light stays on - green). Turn monitor off and back on and same result.


It sounds like you could have either a faulty VGA cable (slim chance) or a faulty graphics processor.

Try using a different cable from a friend.

Good luck!

Black screen not booting


check both your power and video connections to the monitor, sounds more like a monitor power issue.
if the connections appear ok, but screen still blank, try connecting a known good working monitor from somewhere else and see if it works with your pc, if it does, your original monitor is faulty, if it doesn't, you have a pc video issue.
