In the following guide I explain how to replace a cracked or failed LCD screen on a Dell Inspiron 14z laptop.
In my case I’ll be fixing a Dell Inspiron 14z-N411z model.
The LCD screen replacement procedure is relatively simple and all you need is a Phillips screwdriver and guitar pick (or any other piece of plastic).
Turn off the laptop and remove the battery.
Insert the guitar pick between the bezel and display cover and carefully separate the bezel from the cover.
Insert your fingers under the screen bezel.
Wiggle the bezel in order to unlock the hidden latches.
Continue working with the guitar pick.
After you separate the screen bezel on the upper part of the display, move to the sides and lower part.
Remove the screen bezel.
There are four screws securing the LCD screen to the display back cover.
Remove all four screws.
Separate the LCD screen from the display cover and place it the front side down on the keyboard/palmrest assembly.
Now you can access the video cable connector which is located on the back side of the screen.
Remove sticky tape securing the connection and unplug the video cable from the screen.
Remove the cracked or failed LCD screen and replace it with a new one.
Assemble the laptop following all disassembly steps in the reverse order.
You can find a new replacement LCD screen using the model number printed on the back side of the original screen.
In my Dell Inspiron 14z laptop I had the following screen installed: B140XW03 v.0
Replacement LCD screen available here. If you have a different screen model number just search for it.
