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.
Remove three rubber screw seals on the top and two plastic screw seals on the bottom of the screen bezel.
Use a sharp object. After all five (or more) seals are removed, you can remove screws located under the seals.
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.
After all latches have been unlocked, you can remove the screen bezel.
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.
Now we are going to remove the video cable. Unplug video cable from the LCD screen and from the inverter board.
Remove and replace the video cable.
You can search for a new video cable by the part number located on the old cable, just google for it.
Alternately, you can search for a new video cable by the part number located on the connector.
Remove two screws securing the inverter board to the LCD screen. One screw is marked with the red circle, another one is pointed with the red arrow. Disconnect the backlight lamp cable from the inverter board.
Now you can remove and replace screen inverter. You can search for a new inverter by the part number located on the old inverter.
Example 2. The inverter board is located beneath the LCD screen.
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. Then remove two screws securing the inverter board (marked with red circles) and unplug the CCFL (backlight) cable. Now you can remove and replace the inverter.
