This problem is most likely to be caused by a bent or broken pin on the CRT video cable at the VGA connector, OR, this could also be caused by a damaged VGA connector on the back of the laptop. If neither VGA connector is at fault, the problem could be caused a damaged (kinked) CRT data cable, or internal damage to the VGA connector on the back of the laptop, though I suspect the problem is more likely to be external, and you probably won't have to disassemble the laptop to locate the culprit...

Firstly check the connecting cable from the screen to the computer at both ends. Ensure that the thumbscrews that keep the connector in place are tight. Has the PC been moved recently? Any chance the cable could have been put in the wrong place? You can get the installation manual on the following link to see where that cables should go: http://us.lge.com/filedown.do?filepath=1000000757&fileName=L1750B-BF.pdf Try resetting the monitor by pressing the "Auto/SET" button on the front panel for a few seconds with the PC on. If that fails you can do a full factory reset on the monitor by using the on screen menu and navigation to the "reset" function on the setings (gearwheel) page. This is described in the manual page A12. If all this fails then disconnect the cable to the monitor, the monitor should display "no input signal" if it does suspect the PC graphics card is faulty.

Hi this is the way how to examine what's wrong with your LCD monitors. Power on both CPU and monitor. After it went dim and blank, you have to check 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. Like me, I can see window image using flashlight and check lamps inside. Some of them were broken and it is easily replaced. 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.
