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.
STEP 1.
Remove the laptop battery.
STEP 2.
Remove the screw cover located in the lower left corner of the display.
Remove one screw securing the screen bezel on the left side.
STEP 3.
Remove the screw cover located in the lower right corner of the display.
Remove one screw securing the screen bezel on the right side.
STEP 4.
Separate the top side of the screen bezel from the display cover.
STEP 5.
Continue removing the screen bezel.
STEP 6.
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. 
STEP 7.
Remove the screen bezel.
STEP 8.
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.
STEP 9.
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.
STEP 10.
Remove two screws securing the LCD screen on the top.
STEP 11.
Loosen (do not removed) three screw securing the left hinge.
STEP 12.
Loosen (do not removed) three screw securing the right hinge.
STEP 13.
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.
STEP 14.
Remove four more screws securing the LCD screen on the left side.
STEP 15.
Carefully separate the LCD screen from the back cover.
STEP 16.
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.
STEP 17.
Separate the web camera module from the screen.
STEP 18.
Place the screen face down on the keyboard.
The back side of the LCD screen covered with aluminum foil shielding.
STEP 19.
Lift up the shielding so you can access the video cable.
The video cable plugged into the connector on the LCD screen.
STEP 20.
Remove sticky tape securing the connection and unplug the video cable from the LCD screen.
STEP 21.
Now you can remove the LCD screen.

Don’t forget that this laptop comes with two different screen types: CCFL backlit LCD screen and LED backlit LCD screen.
Make sure the find the correct type of screen for your laptop.

I have an HP with vertical lines on the screen.
I would like to use a monitor and have the broken screen lie flat.
How do I “break” the hinges?

@ Stu,
You don’t have to break hinges. You’ll have to remove the entire display panel and use just the laptop base.
Take a look at this HP Pavilion dv4 guide:
http://www.insidemylaptop.com/disassemble-hp-pavilion-dv4-laptop/
You can remove the display panel as it shown in the step 19. After that assemble the laptop back together and use it with an external monitor.
NOTE: the wireless card antenna cables running inside the display assembly. When you remove the display, you disconnect antenna cables from the wireless card. It means you will not be able to use internal wireless card. But it shouldn’t be a problem because you can buy an external USB wireless card.

Sir, thank you thank you. My laptop screen has not worked since I dropped it in the summer. I assumed the screen was OK, because it fell on intersection of the display panel and the rest of the laptop. Been hooking it up to external monitors ever since, which totally defeats the purpose of a laptop.
I do not want to use Laptop Techs (sorry, Laptop Tech) because I am el Cheapo. Besides, the price for a tech would have probably made it worth buying a new laptop (mine was $400). So I first bought a display inverter on eBay for $6. Switching it out made no difference. So I bought a new display cable, and now I’m back in business.
Not sure about making a donation, I’ll think about that. But you def deserve to get paid for this.

I have an HP Pavilion dv7-2273cl laptop that is a couple of years old. Suddenly the screen has red pulsating lines where the black in the screen should be. I don’t know if this is a video card issue, a broken display issue, or a “just run screaming for the hills” issue. Please help me figure out what to do next…

Hi I recently purchased an HP pavilion dv4 from some fool for $20. Problem is the backlight is out I think….. Well it had been displaying complete blackness until my friend took the whole thing apart and put it back together again! Lol now i can see that the screen is displaying but its not lit up so its hardly visible. What do you suppose needs replaced on it?

Hi, I just replaced my broken screen(I have the version with the CCFL backlight) and as far as I can tell, I did everything correctly according to your instructions. When I go to start up my screen, all I get is a black screen. You can tell the backlight is on, the screen is just blank. Do you have any ideas what I may have done wrong before I attempt to disassemble it again? Thanks in advance.

Emily,
It’s possible the video cable not seated correctly on the back of the screen. Try reconnecting the cable.
