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.
Display Assembly Spare Part Number Information
For use with full-featured computer models (includes camera, camera cable, and microphones)
17.0-inch, SXGA+, TFT Single Lamp with BrightView – 432947-001
17.0-inch, WXGA+, TFT Single Lamp with BrightView – 432946-001
17.0-inch, WXGA+, TFT Dual Lamp with BrightView – 432948-001For use with de-featured computer models (includes microphones)
17.0-inch, SXGA+, TFT Single Lamp with BrightView – 432950-001
17.0-inch, WXGA+, TFT Single Lamp with BrightView – 432949-001
17.0-inch, WXGA+, TFT Dual Lamp with BrightView – 432951-001
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.
Display Hinge Kit (includes left and right display hinges)
For use with Dual Lamp display panels – 432964-001

For use with Single Lamp display panel – 432957-001
I already ordered new hinges and display cover and install them soon.

Ken,
If the hinge is broken you have to replace it with a new one. I think that was the main purpose of my guide, wasn’t it?

help!
got the computer apart like your instructions and everything but the hinge is broken on the left side.
what do I do?
Here are photos of what is broken.

I already called HP and they said sorry but it’s not our problem.

Thanks for the writeup. I fixed my (completely broken) left hinge and was even able to salvage a couple of the screw anchors with some epoxy. I used some chinese hinges I bought off ebay. I compared the new hinges to the factory installed ones and I can verify that the ebay ones are much more robust. If you use “dv9000 hinge” in your search on ebay, you can find a set for around $10 shipped. Just expect to wait a few weeks for them to get to you from China. Thanks again!

Andrew,
I hope it works well for you, I’m ready for beer.
November 2nd, 2009 at 12:48 pm
Wow what a write up. Broken Hinge left side which I’m going to do weekend.
If it goes to plan I will donate a tenner to you for the effort that you have put into this site.
Good on you mate.
Have a beer you deserve it.

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.
October 19th, 2009 at 6:30 pm
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?
October 15th, 2009 at 12:57 pm
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
October 7th, 2009 at 8:59 pm
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.
October 7th, 2009 at 8:33 pm
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.
October 7th, 2009 at 5:06 pm
GREAT WRITE UP!!! KUDOS to YOU!!
Caveats: The display spare part number was not indicated anywhere. But, since I also needed to replace the display enclosure (like everyone else), I noticed the spare part for the enclosure was for single lamp LCD. VOILA
October 7th, 2009 at 3:28 pm
I think you are my hero, really. I have the same problem that you explain very well with photos.
I was very disappointed when I discovered that HP closed the SML (service media library) where was uploaded a lot of video for disassembling Pavillion series. Now you have to be a registered partner to take access to library.
So today I decide to replace broken part alone, without any guide and at the end I found your very great page!!!, I believe that my dv9059ea has the bezel screwholes broken on the left. Hinge and enclosure too, by the same side, of sure.
So two question:
1 how can I find the part number for bezel?
2 do you suggest to buy it on ebay?
I hope you answer mw.
sorry for my english, i’m italian

Hello, This is a awesome write up! I have a screen with some lines through it when i move my LCD to view it better, so i’ll most likely be replacing the screen soon. My question to you is, #1, what do you mean when you say you have to replace the cover, in order to re-install the lcd? You mean the shiny peice that looks like it’s aluminum? Is this a must or can i skip it? (Actually re-reading everything, it sounds like you only replaced the cover because you needed to in order to replace your hinge, correct?)
#2, I have a loose left hinge, is their any issues with leaving it loose? It really looks like a simple task but I’d really rather just not fix it at all if it’s not going to effect my laptops performance, and/or mess up any connections to the LCD itself. Thank you for your time!

Kevin,
To be honest, I don’t know. I used original HP part number to find replacement hinges. Will it break again? I don’t know.
September 15th, 2009 at 12:42 pm
Miguel,
New hinges are usually stiff.
September 15th, 2009 at 12:37 pm
Hi Tech, I just got both right and left hinges and replacing them. Only problem is that they are really stiff and can’t move them to the correct position to installed them. Are they supposed to be this stiff? Thank you.
September 13th, 2009 at 9:41 am
Tech,
Awesome write-up, really appreciate the help. I’ll add that in the laptop I was disassembling, there was no part number on the LCD screen cables. I found the part number for the display enclosure up near the webcam/microphone underneath the LCD screen, then matched that up with the part numbers you listed.
I had another question: All of these replacement hinges on eBay say they are OEM original — but we don’t want the original ones again, as they’re just going to break! Are these all redesigned hinges, with different part numbers than the original hinges? Some of them seem super cheap, but the more expensive ones don’t say they’ve been redesigned either.
Thanks,
Kevin

Mitko,
The right hinge is different but the replacement procedure is very similar.
Remove the plastic hinge cover and unscrew the hinge from the base.
September 9th, 2009 at 10:38 pm
Vladimir,
I’ll try to make it more clear.
1. Remove switch cover as it shown in the step 2.
2. Find display part number as it shown in the step 9.
3. Compare your part number with all part numbers listed at the end of this guide and find out if it belongs to LCD with single or dual lamp.
Still not clear?
All you need to know if your LCD has single lamp or dual lamp.
September 9th, 2009 at 6:00 pm
Can somebody explain me how to change right hinge? It is not same as left.
Regards
September 9th, 2009 at 3:38 pm
Yes, I read the entrie guide , but I don’t understand.
1. I go on page 151 and I have “For use with de-featured computer models
(includes microphones)” .
There are 3 options, how to know wich one is my lap-top (SXGA+, WXGA+ , etc) ?
September 9th, 2009 at 2:03 pm
Vladimir,
I guess you didn’t read though the entire guide? I explained that at the end.
1. Find part number for the display assembly.
2. Look up the part number in the service manual and find out if you have dual or single lamp LCD installed.
September 9th, 2009 at 1:56 pm
Hello. I have model Pavilion DV 9308 nr. The both hinges are broken
How to know what kind of Display enclosures I have? Single Lamp or Dual Lamp ?
September 6th, 2009 at 9:33 am
Hello I’m disassembling my DV9202EA. I have the same problem. The left hing is damaged and the backcover of the DV9202EA is damaged. The screwholes were broken.
Also the LCD screen gives many stripes when I turned it on. Could anyone tell me what kind a problem I have. Before I order new parts?
I can leave a picture of the bootscreen. Many thanks for the answers in advance.
Best regards jay
