How to remove and replace LCD screen, video cable and inverter on Dell laptops


This guide explains how you can remove and replace LCD screen, video cable and inverter board on Dell laptops. These instructions should work for most Dell laptops and will be very similar for many other laptop brands.

Example 1. The inverter board is located under the LCD screen.
On this example the display panel had been disconnected from the laptop. It’s not necessary to disconnect the display panel in order to take it apart, you can take it apart while it’s still connected, just do not forget to unplug the AC adapter and remove the battery.

Dell Laptop Display

Remove three rubber screw seals on the top and two plastic screw seals on the bottom of the screen bezel.

Remove screw seals

Use a sharp object. After all five (or more) seals are removed, you can remove screws located under the seals.

Separate screen bezel

Separate the screen bezel from the top cover with your fingers. There will be many plastic latches holding the bezel and the top cover together.

Remove screen bezel

After all latches have been unlocked, you can remove the screen bezel.

Remove screws

Remove four screws on each side of the display panel. These screws secure the LCD screen to the display hinges.

Carefully lift up and remove the LCD screen. Place the screen upside down on your desk.

Disconnect video cable

Now we are going to remove the video cable. Unplug video cable from the LCD screen and from the inverter board.

On some Dell laptop the inverter board is located beneath the LCD screen. Before you can remove the inverter, you’ll have to remove the LCD screen as it explained in the first example.
