How To Troubleshoot A Laptop LCD Monitor

Modern day computers now come with LCD or LED monitors, which have so many advantages as compared to the traditional CRT monitors. These monitors are compact, lightweight, and do not consume much desk space. Secondly, these monitors do not consume much electricity and can even be operated using batteries. Also, the images transmitted by these monitors do not get geometrically distorted and have little flicker.
Are you facing problems with your laptop LCD monitor? Is nothing showing up on your monitor? Luckily, testing a monitor is one of the easier computer troubleshooting steps. By fully testing your monitor using a logical troubleshooting process, you can find out whether your monitor is working properly or not and then take necessary action to get it back up and running. Follow these easy computer repair troubleshooting steps to test your monitor.

  • First step is to diagnose the problem. Hook up the laptop to an external display unit, such as a projector or a desktop monitor. If you are able to see images or videos in the external unit, it means the problem lies with the laptop’s LCD display and not with its video card or motherboard. 
  • To fix the laptop LCD problem, first you need to shutdown the laptop. Make sure that the power cord is unplugged from the laptop and the wall outlet. Now you need to remove the laptop battery. Take off the plastic cover and raise the battery from its dock under the laptop.
  • First, you need to remove the bezel (plastic frame around the LCD screen). Refer the laptop manual and carefully remove the screws. Gently pry the rubber seals loose with a flat tipped tool to expose the screws. Remove all the screws and place them in a small container away from the work area.
  • After all the screws have been removed, use your finger to dislodge the bezel. Place a finger between the frame and the screen and pull the finger toward you to loosen it. Start from the bottom center and go all around the frame to completely detach it from the LCD panel. Locate and undo any locking mechanism such as clips or hooks to free the bezel.
  • Now, check the cable connections on either end of the inverter board. Now that you have removed the bezel, you will be able to see the bare LCD screen enclosed in a thin metallic frame. Locate a small green component-the inverter, usually taped at the bottom of the screen, and unplug its cables. Unplug the video cable, taped to the back of the screen, from the motherboard. Reattach the cables and turn on the laptop. 
This simple troubleshooting method should fix the problem with your laptop LCD screen. If the problem persists, better contact a computer repair technician and get it fixed quickly.
