Image appears for 2-3 seconds then screen goes black

The following steps are how to examine what's wrong with your LCD monitors. After you turned it on and the screen went black, 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,

I have the same problem with a dell monitor. I was going to set it up because I have an old school monitor, and wanted to switch to a flatscreen. but now I have to switch back to the oldschool one because this didn't work D:
it's a pain in the *** to move, too ;;;

Have had 2 of these screens do this - both times it was swollen caps of control board. Take it apart and check if any caps are bulged. If so replace. Best to replace the whole set as this was part of the world wide caps problem.
