Hi this is the way how to examine\015\012what'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\015\012not by shining a flashlight into the screen, not directly but find the best\015\012angle to the screen and take a look very closely. If you can see the icons or\015\012any image, there will be a minor problem. This is because of the lamps inside\015\012screen. Some of them were broken and it is very easy to replace. If you cannot\015\012see anything on the screen, there'll be some problems with inverter board. If you\015\012have soldering tool and want to fix it by yourself, check the caps first. It\015\012may cause this problem. Some caps might show leaking or burn spot on the board\015\012because of too high temp. If you don't have soldering tool, you better go get a\015\012technician to do so.\015\012Hope this help!! If anything I can help you with, feel free to let me know.
\015\012\015\012Thank\015\012you,
