In this post I explain how to disassemble the display panel on an HP Pavilion dv7 series notebooks.
I’m taking apart an HP Pavilion dv7t-1000 notebook PC but my instructions should work for all models in the Pavilion dv7 line. If this guide works for you please mention the notebook model number in comments after the post.
By the way, in the previous guide I explain how to completely disassemble an HP Pavilion dv7 series notebook.
Before you start, turn off the laptop and remove the battery.
STEP 1.
There are two screws securing the LCD screen bezel to the display cover. These screws are located in the lower left and right corners and hidden under two screw covers.
Using a sharp object remove the left screw cover. After that remove the screw.
STEP 2.
Using same technique remove the right screw cover. After that remove the screw.
STEP 3.
Start separating the LCD screen bezel from the display cover on the top. You can use a guitar pick as a case cracker.
Insert the guitar pick between the bezel and cover and slowly move along display side. Continue removing the screen bezel with your fingers.
STEP 4.
Continue removing the LCD screen bezel.
STEP 5.
Screen bezel removed.
STEP 6.
The screen inverter board is mounted below the LCD screen. There are no screws securing the inverter.
Lift up the inverter board and disconnect cables on both ends.
STEP 7.
Remove the screen inverter board.
STEP 8.
Remove eight screws securing the LCD screen assembly to the display cover.
STEP 9.
Separate the LCD screen assemble from the display cover and disconnect one cable from the web camera module.
STEP 10.
Now you can access the video cable connector on the back of the LCD screen.
STEP 11.
Unplug the video cable from the LCD screen.
STEP 12.
Remove four screws securing the LCD screen to the mounting bracket on the right side.
Remove four more screws on the left side (picture not shown).
STEP 13.
Carefully remove the LCD screen. Now you can replace it with a new screen if needed.
You can find a brand new LCD screen for HP Pavilion dv7 series notebooks here.
UPDATE: I forgot to mention that HP Pavilion dv7 series notebook might have two different types of LCD screens installed.
1. LCD screen with CCFL backlight. This screen has a backlight lamp inside which requires the inverter board (shown in steps 6 and 7).
2. LCD screen with LED backlight. This screen doesn’t require the inverter board because there is no backlight lamp. If you have LED LCD screen in your laptop, you’ll have to skip steps 6 and 7.

I have a HP Pavilion Qdvt7-3300 and this worked great!!! Thank you Thank you Thank you!!! so much! Nonetheless, I did not find an inverter board when taking out the screen. (Not that this matters for my purposes, but I am still curious.)
Questions:
1) Is it possible for my laptop to not have an inverter board?
2) Is it possible for the inverter board to be somewhere else like closer to the motherboard?
3) There is a square area covered with some sticky foil behind the screen, Is it possible for the inverter board to be square and hidden under this sticky foil?
4) Is it possible for the inverter board to be permanently attached to the screen? (e.g., when I buy a new screen a new inverter board comes with it, because the inverter board is part of the screen.)
My screen model is: LP173WD1(TL)(C2)

All I can say is Thank You, Thank You, Thank You!!! I consider myself to be pretty capable of doing most things, but I was feeling a little intimidated after watching a couple of differ youtube video. After finding your instructions, I was able to tackle replacing my screen within 1 hour – mostly because I didn’t have a small enough screwdriver and had to use the end of a sharp knife! My laptop is a dv7-3188 so it was a little differ than the above but easily figured out. I’ve gotten it done and it looks GREAT! Our local computer store was going to charge me $130 for the screen and $66 to put it in. Now I only have a total of $82 into it…so, so excited! I think my husband should let me spend the difference

Hey again!
Yes,i’ve tried that before i decide it to taking apart the entire laptop and display aswell!Normally,this is the first step when you decide to isolate the failure…So,i’ve take it out the lamp,and has the both edges black,so i presume it’s old &burned.
Now,i’m waiting for the new lamp,already ordered from the link you’ve posted.
Thanks a lot for your fastest reply,and i’ll keep you informed.
All the best!

@ Toni,
Maybe it’s a stupid question but have you checked LCD screen brightness settings in Windows OS?
Normally you should be able to increase/decrease LCD brightness using a keyboard shortcut.

@ Henry,
Most likely you are correct. I hope you know how the inverter looks like.
There shouldn’t be any glue. Usually the LCD screen secured by screws. Take a look at the service manuals I provided earlier. They should have the LCD screen installation diagram or removal instructions.
Most likely you are correct. I think this is LCD screen failure and the screen has to be replaced.
Just in case, test your laptop with an external monitor. How about external video? It should have normal colors.
