the monitor is not getting any video information from your computer .. check the connection at the computer to make sure it is fully plugged in .. make sure the video card (if it has one) is securely in place ... make sure the monitor is actually plugged into the right connector .. you may have a bad video card or a damaged cable to your monitor .. you can plug the monitor into another computer to make sure its ok ..
There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc. http://en.wikipedia.org/wiki/Capacitor_plague Please post back what you find.
You have a blown power supply. If it is less than a year old its under warranty, send it in for repair. If it is out of warranty our site can show you how repair the internal power supply. Our site is : www.ccl-la.com/badcaps.htm click on the link at the bottom for monitor repair.
I hope this helps, if so please rate our solution.
Hi; I had the same problem. I know that sometimes devices require you to perform some type of '10-30 second' "hold" of one or some of its buttons in order to 'reset' the device, so to speak. So, having said that, try this:
1) Turn your monitor off (no green light) but leave it plugged in. 2) Leave it off for about 10 seconds. 3) Hold the  button on your monitor (the one to the immediate LEFT of your monitor's POWER button). 4) While holding the  button, now press and HOLD your POWER button. 5) Wait for your image to appear and STAY onscreen for about 5 seconds, then release both buttons. 6) Your monitor should retain its onscreen image.
The monitor is not receiving signal from the computer. Is the power light on on the computer? If so - press and hold power button on computer until the power light goes off, then press again to restart. If the computer starts and you still have no picture it is most likely a video card or motherboard problem.
Monitor going black after a few seconds can be caused by a faulty power supply or inverter. Some monitors have both as one unit.
Sometimes it is basic failed capacitors, After that then I would look at transistors.
The average monitor from 17 to 20 and sometimes the 22s have usually 4
bulbs in them. One bad bulb will also cause the inverter to not fire up.
Bad bulbs usually show pinkish tint, or flickering or are dark at center top or bottom of the display.
Had the same problem, turned out it was due to a faulty capacitor on the inverter board, 680uF 25V (105 celsius rated). Simple to fix once you have the unit dismantled and the correct replacement part. Two screws hold the shroud on, but you need to be careful with an (old) credit card levering it off.
