This guide explains how you can remove and replace the LCD screen, video cable and inverter board on a Dell display.
These instructions should work for many different Dell models.
Example 1. The inverter board is located under the LCD panel (not common).
In this example the display panel has been removed from the rest of the laptop case.
In most cases it’s not necessary to remove the display.
Remove three rubber screw seals on the top and two plastic screw seals on the bottom of the display bezel.
After all five (or more) seals are removed, you can remove screws securing the bezel.
Separate the bezel from the display assembly with your fingers.
There will be many plastic latches holding the bezel and the cover together.
After all latches unlocked, you can remove the bezel completely.
Remove four screws on each side of the display panel. These screws secure the LCD panel to the display hinges.
Carefully lift up and remove the LCD panel from the cover and place it upside down on your desk.
Unplug the video cable from the screen and from the inverter board.
Remove and replace the video cable if necessary.
You can search for a new cable by the part number located on the sticker.
Alternately, you can search for a new video cable by the part number located on the connector.
Remove two screws securing the inverter board. 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 the inverter. You can search for a new inverter by the part number located on the old inverter.
Example 2. The inverter board attached to the LCD frame (more common).
In some Dells the inverter board is mounted into a metal bracket on the bottom of the LCD panel.
Before you can remove the inverter, you’ll have to remove the LCD panel from the display as it explained in the first example.
After that remove two screws securing the inverter (marked with red circles) and unplug the CCFL (backlight) cable.
Now you can remove the inverter from the bracket and replace it if necessary.
