In the following guide I explain how to remove and replaced damaged LCD screen in HP Pavilion dm4 laptop.
This is second part of the HP Pavilion dm4 disassembly guide. In the part one I explained how to take apart laptop base and remove display panel.
There are two screw covers in the lower left and right corners of the screen.
You can remove both covers with a sharp object.
On the following picture I’m removing the left screw cover.
Remove the screw.
On the next picture I’m removing the right screw cover.
Remove the screw.
Insert a piece of soft plastic between the LCD screen bezel and display cover and carefully separate the bezel.
I’m using my favorite case cracker – the guitar pick.
There are some hidden latches securing the screen bezel to the display cover. You’ll have to wiggle the bezel in order to unlock the latches.
Continue separating screen bezel from display cover.
The bezel separated on the top of the display assembly. Now you can move to the bottom part.
Finally, the screen bezel has been removed.
Remove four screw securing the LCD screen.
In a HP Pavilion dm4 laptop you’ll find a LED backlit LCD screen installed, so there is no inverter board like in most older laptops.
Carefully separate the LCD screen from the display cover and place it face down on the table.
On the back of the screen you’ll get access to the video cable and webcam cable bundled into one harness.
The webcam cable glued to the back of the LCD screen with double sticky tape. Unglue the cable.
Unplug the video cable connector from the LCD screen.
Now you can remove the LCD screen and replace it with a new one.
You can search for a new replacement LED backlit LCD screen using the model number printed on the sticker.
In my HP Pavilion dm4 laptop I had the following screen installed: B140XW02. It’s version 2 but I don’t know if the version number makes any difference.
On the following picture you see the display cover with LCD screen removed.
