How to Fix Laptop Screens | Comprehensive Troubleshooting Guide To Resolving Various Issues

To fix laptop screens, follow the guidelines given below.

  1. Unplug your laptop power cable from the power source. Remove the battery as well and put it in a safe place not far from your working area as you'll need it again.
  2. Locate the cover stickers. Check at the bottom of the bezel, adjacent to the hinges.
  3. Remove the cover stickers from the screen bezel using a sharp tool like a safety pin. Put the covers where you can reaccess them. 
  4. Remove the bezel screws using a screwdriver. These are found at the front section of the frame. Remove all of them and put them together in a secure place.  
  5. Disengage the bezel from the screen. Remove the bezel by navigating your finger through the middle of the bezel and the screen. When there is enough space between them, pull the bezel off the screen. At this moment, the bezel should snap out freely. Otherwise, engage it gently from different angles until it comes out free. 
  6. Inspect from the screen angle to confirm that you had removed all the screws because If any bezel screw is still intact, the bezel won't come out. If any, remove it using a screwdriver before attempting to remove the bezel again. 
  7. Disconnect all cables connecting the screen.
  8. Find the video cable and remove the tape before disengaging the connector, which is found at the rear side of the screen. The video cable is the long ribbon wire attached to the backside of your screen. 
  9. Remove the power cable attached to the back of your screen. 
  10. Using your screwdriver, remove all screws holding the screen to the metal frame and put them where you can access them later. These screws may be lacking in some laptop models (see top thin laptops).  
  11. At this moment, the screen should be loosely attached and free to be removed. Remove it from the metal frame. Do this by gently tilting it forward and pulling it off. 
  12. Put your screen on a secure platform so that you can look at it some other time if you have to. But if the screen is spoiled, you can dispose of it.
  13. Take care while removing the screen because it may contain broken parts that can be harmful.

Installing the new screen:

  1. Check at the back or side of the screen for the label. This label should contain the model number of the screen and the manufacturer's credentials. Another specific on the label is the barcode. Use this information to find a suitable replacement for the screen you've removed.
  2. Get your replacement screen from a local electronics hardware shop or online vendors. You may need to confirm that the new screen is of the same model number and from the same manufacturer as the old one to fit in your laptop easily. Depending on your laptop and the brand, acquiring the new screen will cost you as little as $100 or as much as $300 for best gaming laptops, for example. 
  3. Fix the new screen onto the metal frame by gently sliding it. Be sure to put it in the proper orientation.
  4. Screw the new screen into the frame.
  5. Return the bezel in position to hold the screen in place.
  6. Screw back the bezel to hold the screen in position firmly.
  7. Put back the rubber covers to cover the screws.
  8. Connect back all connecting cables to the back of the screen.
  9. Connect back the video cable to the rear side of the screen.
  10. Plug in the power cable to the back of the screen.
  11. Inspect to ascertain that all cables are correctly connected to the new screen.

Finishing Up:

  1. Return the battery to the laptop and plug the laptop into a power source.
  2. Confirm that the screen you've installed works before you can fix the screws. Power on the Laptop to confirm if it starts and that the screen works correctly.
  3. Try simple operations on the laptop, ensuring there are no lines or distorted graphic images on the screen.
  4. Put back the bezel to hold the screen firmly.
  5. Fix the bezel screws around the bezel for a firm drip of the screen.
  6. Tighten the screws using a screwdriver and put the rubber covers over them. 

After this, you're good to go.
