The problem is with the Backlight inverter. For some reason the overcurrent trips after a few seconds. I got around it by hacking the inverter to prevent the overcurrent from tripping, but if you aren't familiar with electronics, I can only suggest a new screen.
On another question related to LCD monitors turning on and off within a few seconds, people suggested that aged/burnt out capacitors on the powerboard inside the monitor needed replacing. A relatively easy job for any technician to do.

Hello there: This normally means that the cable that goes to the computer from the monitor is not getting any signal from the video card This is due to a couple of possible problems the graphics card is not compatible with the monitor Or the graphics card is faulty or dirty and needs to be removed and cleaned with rubbing alcohol and than reinstalled I would first try this on a different computer to see if the monitor now works if so han you know you have a graphis card problem but if it does not work than you know that the monitor is the one with the problem It may have a faulty controle circuit on it and needs to be serviced or jut simply replaced ok If you do take the video card out of the computer Unplug the power supply to the computer than remove the power supply cord to the mother board and press in on the power button for 1 minute this will release any esd (electrical static dicharge) that is built up during operation than attach it back on the mother board and continue to remove the graphics card and make the replace ment or repairs needed ok I hope this is very helpful for you Best regards michael
