LCD monitor troubleshooting first requires patience. If the monitor doesn’t work, the first thing you need to do is check if everything is plugged in properly. Also examine if the cord is properly connected. You may also remove power and CPU connections and put them back again. But before this, make sure that you know which cable needs to be connected. In case of a working monitor, if the display is disturbed or there is a change in the picture quality, the cable is at fault and needs to be replaced. If the monitor is working fine but goes out after the window loads, the graphic drivers are the culprit.

There are some LCD issues that are partially related to the operating system, such as a flickering screen. If you observe the problem when the PC is booting, the monitor is at fault. But if the problem is not observed until the OS boots, there may be an issue with the drivers, and you need to check the display settings or reinstall the monitor drivers. You also need to check if the problem lies in the video card. Try to use another pc lcd monitor with the computer, if it works fine, then there is a possibility of driver issues.

Some of the other problems with LCD monitors may include dead pixels, which are pixels that only display black or white colors regardless of the displayed image. If a larger part of the screen is covered with such pixels, you can do nothing to resolve the problem other than buying a new monitor. However, this type of problem is rarely found nowadays. If the screen is showing a lower picture quality, you may just need to check the selected resolution. The resolution settings may also be adjusted if the text is not displayed efficiently. Another problem that can be encountered with the LCD screen is a green or pink shade on the display. In this situation, the ribbon connector cable of the laptop may be at fault. On an computer lcd monitor, the monitor cable is to be replaced to rectify this problem. Replacing the connecting cables even solve the problem of monitor flickering.

If the monitor doesn’t work even after following all lcd monitor tv repair steps, the last option would be taking assistance of a computer hardware engineer. If the monitor’s condition is really bad, the engineer might even suggest replacing the monitor.
