In this guide I show how to replace LCD screen on HP Pavilion dv4 laptop.
HP Pavilion dv4 laptop comes with two different types of screens installed:
1. LCD screen with CCFL backlight (requires screen inverter).
2. LCD screen with LED backlight.
In this guide I’ll be replacing LCD with CCFL backlihgt.
Also you can use this guide for replacing LED LCDs but they don’t have inverter boards so you’ll have to skip steps 8 and 9.
Before you start make sure the laptop is turned off.
Remove the laptop battery.
Remove the screw cover located in the lower left corner of the display.
Remove one screw securing the screen bezel on the left side.
Remove the screw cover located in the lower right corner of the display.
Remove one screw securing the screen bezel on the right side.
Separate the top side of the screen bezel from the display cover.
Continue removing the screen bezel.
When the top side of the bezel separated from the display cover, move to the lower part.
Lift up one side of the bezel with a small screwdriver.
Work slowly. There are hidden latches securing the bezel. Try not to break all of them.
Remove the screen bezel.
As I mentioned before, this HP Pavilion dv4 laptop has a CCFL LCD screen which requires an inverter board.
The screen inverter mounted on the lower part of the display assembly.
There are a few plastic tabs securing the inverter board.
Lift up the inverter board and disconnect cables on both sides of the inverter.
Remove the inverter.
Remove two screws securing the LCD screen on the top.
Loosen (do not removed) three screw securing the left hinge.
Loosen (do not removed) three screw securing the right hinge.
Now you should be able to separate the LCD screen from the display cover just enough to access screws on both sides of the LCD screen.
Remove four screws securing the LCD screen on the right side.
Remove four more screws securing the LCD screen on the left side.
Carefully separate the LCD screen from the back cover.
The web camera module still attached to the LCD screen.
The web camera IS NOT a part of the screen but it’s attached to the screen by two sticky aluminum strips.
Disconnect the web camera cable on the left side.
Separate the web camera module from the screen.
Place the screen face down on the keyboard.
The back side of the LCD screen covered with aluminum foil shielding.
Lift up the shielding so you can access the video cable.
The video cable plugged into the connector on the LCD screen.
Remove sticky tape securing the connection and unplug the video cable from the LCD screen.
Now you can remove the LCD screen.
