How to Fix a Laptop Backlight Problem


One component that every laptop computer has in common, regardless of the model, is the screen. If you own a laptop computer and notice that the LCD screen is dark or dimming, then chances are that the backlight is dead or dying. The good news is that this is a problem you can fix on your own if you don't have the money to take it to a service technician. And since the backlight is located in the same place in almost every screen, this guide should be of help no matter what brand of laptop you're using.

Things You'll Need

  • Phillips screwdriver
  • Replacement backlight
  • Power off your laptop and remove the battery. If your particular computer's battery cannot be removed, make sure the AC adapter is unplugged.

  • Remove the screws on the side of your laptop screen. Once the screws are removed, you can remove the plastic bezel (screen guard).

  • Pop the bezel out, exposing all of the LCD screen. Pull the LCD screen gently away from the computer by the corner. Be mindful that the screen is still connected to the computer by a ribbon cable.

  • Remove the tape over the ribbon cable where it connects to the screen, and gently pull the cable to disconnect it.

  • Turn the LCD face down, and remove the piece of tape that holds the top metallic foil against the back of the LCD.

  • Lift the metallic foil to expose the backlight. Remove the single screw at the end of it that holds it in place.

  • Unclip the wire at the end of the backlight from the inverter (power source to the backlight), and remove it from the LCD. Replace it with the new backlight (available at any electronics store or online), and reassemble the device the same way you took it apart.
