I used to repair LCD monitor from
Dell. It works for me. You might be using these following steps to examine what
wrong with your monitor. After you turned PC on and monitor stopped working or
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 (Start menu), there will be a minor problem. This is because of CCFL
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.
