Hi this is the way how to examine
what's wrong with your LCD monitors. After you turned it on and the screen
blacked out or stopped working, you have to check that if you can see the image on the screen or
not by shining a flashlight into the screen, not directly but find the best
angle to the screen and take a look very closely. If you can see the icons or
any image, there will be a minor problem. This is because of the lamps inside
screen. Some of them were broken and it is very easy to replace. If you cannot
see anything on the screen, there'll be some problems with inverter board. If you
have soldering tool and want to fix it by yourself, check the caps first. It
may cause this problem. Some caps might show leaking or burn spot on the board
because of too high temp. If you don't have soldering tool, you better go get a
technician to do so.
Hope this help!! If anything I can help you with, feel free to let me know.
Thank you,

This is most likely the power inverter board in the monitor - this is common in many monitors. If it started taking longer and longer to display an image, and the power light is blinking on-and-off, that's the problem. You can confirm that it's the monitor and not your computer or the cable by plugging in another monitor if you have one to try. If it's under warranty, send it back, if not, there are inverter boards for many common models of LCD monitors that are replaceable The board can run anywhere from $50 on up. Depending on how old your monitor is and how much you've invested into it, you may find it better to just replace it with a gently used one from ebay.

Most failure in LCD monitors are due to cheaply made caps being use. If you are going to DIY repair, please read below, or if you are going to have it fixed then at least you will know if you are being ripoff or not.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed SAMSUNG monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

in most cases it is a capacitor on the power board look for a bulging cap or leaking
