I am not familiar with your particular model, but I do know what the problem is.
The inverter that runs the lights behind the screen is faulty and needs to be repaired. The lights shine from the top and bottom and reflect outwards through the panel so you can see what is on the screen. If you start the computer up, then shine a bright light into the panel you will see an image on the screen, but very feintly.
This can be cheap, it can also be expensive depending on where you go to get it repaired. Call aorund to a few TV shops in your area to get a rough idea on prices.
Hope that helps =)

I have exactly the same problem with my X20G monitor. There is a design problem with the LCD controller board and the Power supply board. The problem is the power sequencing of the power supplies feeding the LCD controller chip. The 2.5V rail has to come on first before any other power rails. Also, some of the power rails don't discharge completely during power down. I was able to fix my X20G by adding a wallmount power supply to feed the 2.5V DC-DC converter input (blue wire) and adding bleeder resistors on two of the power rails on the LCD controller board to discharge it during power down. With this setup, I do the power sequencing by plugging the wallmount power supply first before the plugging the main AC power of the monitor. Only try this fix if you have good knowledge of electronics.

usually this happens due to static try to power cycle the monitor by disconnecting all the cables from the monitors
then connect teh cables back one by one
and see if it works and if not yes get teh monitor replaced
