In the following guide I explain how to replace the left hinge in a HP Pavilion dv9000 laptop.
Broken left hinge is a known issue with HP Pavilion dv9000/dv9100/dv9200/dv9400 series laptops. A while ago HP was fixing this issue at no charge under the service enhancement program. This program has expired on May 31, 2009 and now you are on your own.
I believe this guide will work with some other HP Pavilion laptops even though replacement part numbers can be different. If it works for you, please mention the laptop model number in the comments below.
I will explain how to find correct parts for this repair at the end of the guide.
STEP 1.
Remove six screws located in the battery compartment. These screws secure the switch cover.
STEP 2.
Remove the switch cover and place it upside down on the keyboard. Be careful because the switch cover is attached to the motherboard via a flat ribbon cable.
For more detailed instructions for removing the switch cover please check out my previous guide about removing the keyboard.
STEP 3.
Remove five screws seals from the display bezel.
Remove all five screws found under these seals.
STEP 4.
Remove display bezel.
You’ll find more detailed instructions for removing the bezel in my previous post about removing and replacing the LCD screen.
When you remove the display bezel, you can take a closer look at the left hinge damage.
STEP 5.
Disconnect the screen backlight connector from the right side of the inverter board.
Remove six screws securing display hinges. Three screws from each hinge.
STEP 6.
Now you can separate the display cover from the LCD screen and access the video cable.
Remove sticky tape securing the connection and unplug the video cable from the LCD screen.
STEP 7.
Remove two screws from each side of the screen. These screws securing the LCD screen to the hinge brackets.
STEP 8.
Remove the LCD screen.
STEP 9.
Remove three screws securing the left hinge.
By the way, the display part number is located on a sticker glued to the video cable connector. Write down the display part number because you’ll need it later in order to find correct hinges for your laptop. In my laptop the display part number is 432949-001.
STEP 10.
Remove the left hinge assembly from the laptop.
STEP 11.
Separate the hinge cover from the hinge.
The broken left hinge is removed and ready to be replaced with a new one.
Unfortunately, in my laptop I found another damaged part, it’s the display cover.
All four screw anchors are missing and if I assemble the display panel like that, I will not be able to screw the left hinge to the display cover. The display cover has to be replaced too.
After you remove the LCD screen, it’s very easy to replace the display cover. Simply unglue the wireless card antenna cables, microphone cable, webcam cable (if you have any) from the cover and replace the cover with a new one.
How to find new hinges and display cover.
HP uses different LCD screens in Pavilion dv9000/dv9100/dv9200/dv9400 laptops. Some LCD screens come with single lamp, others come with dual lamp.
I found all LCDs listed in the service manual for HP Pavilion dv9000 and dv9200 on the page 151. By the way, for dv9100 and dv9400 HP links to the same manual and I assume you can use same part number for these models too.

In the step 9 I found that I have 432949-001 screen installed in my laptop, so I have to use hinges and cover for screens with single lamp.
You’ll find part numbers for display hinges and display cover (enclosure) on the page 87 in the same manual.

Dean S,
That’s exactly why you pay someone for service.
You cannot.

I have a broken left hinge. I am having someone come and repair the laptop once I get the parts…the problem is I don’t know which part to order. How can I tell (without taking the thing apart to see the part sticker) if i have the single or duel lamp display?
I have a HP Pavillion dv9000 with a webcam built in to the screen.

Dave D,
If the laptop has video on the external monitor but not on the internal LCD screen, the problem is related to the display panel somehow.
1. Is it possible that you accidentally pulled the cable from the back of the LCD screen?
2. Is it possible that you accidentally damaged the video cable?
3. Did you use right size screws? Maybe the screw is too long and shorting the motherboard. Just a guess.

I had a broken right hinge, and hinge cover. The actual hinge didn’t break, but the little rectangle shape protusion on the bottom that locks the hinge in place had broken off. I tightened up the two right hinge screws that come up from the bottom and it is nice and tight now. I plan on ordering a replacement hinge so I can make a proper repair. The only problem is that now my screen is black, totally black, like there is no power going to the screen. An external monitor works fine. I didn’t disconnect the cables, so that’s shouldn’t be the problem. I even went back and checked them, they are still in place. I’m getting real good at taking the case appart and putting it back together. I wish there was a way to test it before I put everythign back together! I tried pressing the Function+F4 keys, but all that does is make the remote monitor flicker, then give me to option to choose the remote monitor.
Any suggestions?????

Greg,
Take a look into the video connector on the motherboard. Maybe you accidentally bent one of the pins? Make sure there are no bent pins inside the connector.
Also, have you reconnected video cable on the back of the LCD screen? Maybe you accidentally pulled the cable from the connector?

I did this, but after I finished and turned the laptop back on, my display will only work on an external monitor. I checked to make sure that all the connections were good, but still nothing. the backlight turns on like it is going to work, but that is all it ever does. It just leaves me with a bright, black screen. I hooked it to my tv however and it works just fine. This is not really ideal for me since it’s a laptop and I would like to be able to use it anywhere. Anyway, if you can think of anything else I should check into let me know. Otherwise, I’ll try and take it somewhere or just trash it.

I just finished replacing both hinges – they both broke. I bought them from ebay for $20. They seem to be working fine. My back cover had the damaged screw anchors, but I am going to see if I can hold off replacing. So far it is working. A few notes:
– The right hinge’s screws are on the bottom of my laptop.
- look to see how the wires for the screen are when taking it apart (they are under the black cover of the hinge) or you can not get the bezel on correctly
- make sure you plug the video cable back in correctly or you will have to take your laptop back apart!
Good Luck!

Hello, I’m french, sorry for the language. I bought the hinges left and right dv9000 on EBAY. They are completely different, is this normal? , they are stiff, is this normal too? I have not yet installed THANK YOU

Chris,
I replaced the cover only because it had damaged screw anchors. Otherwise, I wouldn’t replace the cover.
If you have a failing screen, replace just the screen.
I cannot tell without looking at the laptop. If the hinge is still in good condition, do not replace it. But if it fills like the hinge is going to fail soon, replace it with a new one so you don’t have to disassemble the laptop two times.

Paul,
When I search HP website for dv9059ea, it brings me to the service manual for the entire dv9000 line. I believe you can use same parts as in dv9000 notebook.
Here’s the manual: http://h10032.www1.hp.com/ctg/Manual/c01311536.pdf
Go to the page 5-39 with the display disassembly instructions. You’ll find display part numbers in there. Just google the part number and find where you can buy it.
