HomeIn 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.
STEP 1.
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.
STEP 2.
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.
STEP 3.
Continue separating screen bezel from display cover.
STEP 4.
The bezel separated on the top of the display assembly. Now you can move to the bottom part.
STEP 5.
Finally, the screen bezel has been removed.
STEP 6.
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.
STEP 7.
Carefully separate the LCD screen from the display cover and place it face down on the table.
STEP 8.
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.
STEP 9.
Unplug the video cable connector from the LCD screen.
STEP 10.
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.
New replacement LCD screens available here.
On the following picture you see the display cover with LCD screen removed.

My laptop screen in my HP is black but all the other lights are on the screen will not turn on. I turned it on and off, I took the battery out. I Reyes Messina with the screen, and it came on for a deciding and the next to.e I turned it on it went completely black. I am now in the process of taking off my screen and trying to fix the problem. Any help?

Hi there!
First off, thanks for the great guide. Installed a new screen on my dm4 and it works like a charm. So empowering to be able to have done this myself (and great to have saved so much money).
Just one problem… I lost two bezel/hinge screws (the ones under the plastic covers shown in step 1).
Do you know what size these screws are exactly? I’d like to replace them but I’d like to avoid purchasing an entire replacement screw kit.
Thanks!!
Best,
Adam

Hi, i’m having an HP dm4-1042tx. i recently had my laptop fan cleaned by a friend of mine. but after that the brightness start to act weird. the display seems too bright although its in default position (50% brightness) and the color seems kinda blur (not to contrast). the point is the display is not the same as before (with the same settings). i tried to uninstall and reinstall the graphics driver, but no results..
is this a hardware or a software problem? what can i do to fix this.
thanks for the help

I am having the some what of the same problem as Bendik, My screen is coming on and it looks like it works fine but the graphics are coming out green and purple. when I took apart my laptop to reconnect the screen I noticed that the video cable connector was a little bent but fit right in. Could this be the problem? and could that be replaced? and where do I get one from? Thanks BTW your tutorial was awesome!!! if only i didnt have this small problem.

I have found sites that sell the screen itself but what if I need the display cover. The bracket where you remove the first screw is busted on my laptop.

@ Michaela,
You confused me with too many display covers.
Are you talking about the screw anchor on the display BACK cover?
If the screw anchor is broken and because of that the entire display is loose, you’ll have to replace the BACK cover.
I hope I understood you correctly.

The srcreen is working properly and so is the webcame and speakers. Its just secureing the screw to the bezel and display cover.
