Re: LCD Monitor needs repair
I used to repair LCD monitor from
Dell. It works for me. You might be using these following steps to examine what is the problem of your LCD 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. You don't need to do anything with the inverter board in this case.
If you cannot see anything on the screen, there'll be some problems with
inverter board.Hope this help!! If anything I can
help you with, feel free to let me know. Thank you,

That is often an inverter failure. Try turning off the room light, and point a flashlight sticking to the dark screen. If you can see a very faint picture, then the inverter has failed. Before replacing the inverter, the PSU must also be tested. If the PSU does not supply power to inverter, then the PSU and not the inverter is the part to be tested.
If the screen is not dark, but there is backlight and no picture, then the problem is not the inverter. In that case check the source and the connection cable. If the cable is OK, then it is usually the main controller board inside the monitor. Once again the part must be tested.
More often then not, this is attributed to a failing Backlight Inverter. A Backlight Inverter, is a power board mounted below the screen that actually send power to the Lamp inside the LCD itself. Check to see, when it goes out if there isn't still some images faint in the screen. If this is the case take it to a local repair shop and have them order one and replace it. repair cost for this shuold be around 65-100 dollars.
