This means there is a hardware failure in the monitor that could be either blown CAPs or a shorted out inverter. It is difficult and dangerous to replace both of those(involving soldering and desoldering) if you don't know how as LCD's are made of a hazardous material. I would try new cables and on a different computer as a last resort and if that doesnt work then your monitor is trashed. If it works on another computer then the issue is not with your monitor. Good luck!

If you can open up the monitor from the back and get the cover off. Look on the power board and see if there are any puffy capacitors, most of the caps will have a silver flat top but if there are any bad ones, they will have a puffy top that stick up.
If you see any then make sure you replace them with capacitors of the same Uf rating and at least the same volts or more.
If you don't see any puffy caps then that means the screen is bad and the whole monitor would need to be replaced.

Testimonial: "Opened the LCD monitor up, and it was as he said. A bad capacitor. Thanks!! Replied within minutes."
disconnect all the cables except the power cable and then turn the monitor on you would see a test screen if it still happens your monitor is faulty and better buy a new one as repairing is usually expensive .

The problem can be the inverter transformers or lamps assembly.
You can look for number as printed on the transformers and go to www.lcdparts.net to look for pinout and resistance reading. Checking for bad lamps will be more difficult unless you have spare test lamps.
One thing you will have to remember is that the cap can look OK but it can have high ESR, you will need cap tester that can do the test.
