In this post I explain how to remove screen inverter and replace LCD screen in a Compaq Presario m2000 laptop. It’s way easier to disassemble the laptop display panel when the display panel is separated from the laptop. You’ll find instructions for removing the display panel in my previous guide for Compaq Presario m2000 laptops, just follow steps 1,2,3,9,10. This guide might work for some other Compaq Presario laptops. If it works for you, please mention the laptop model in the comments below.
It is possible to remove the inverter and LCD screen while the display is still attached to the laptop but it will be harder to remove the screen bezel.
If the backlight in your laptop stopped working and the image on the screen is so dim that you can barely see it under bright light, most likely you have a failed inverter board. There is a good chance to fix the problem if you replace the inverter board.
If you replace the inverter board but the image is still dim, most likely there is a problem with the backlight lamp inside the LCD screen. If that’s the case, try replacing the LCD screen.
Before you start make sure the laptop is turned off and the battery is removed.
STEP 1.
There are six screws securing the screen bezel to the display cover. These screws are hidden under six rubber seals. You’ll have to remove these seals first.
Remove screw seals with a sharp object. These seals have a sticky bottom. You can glue them somewhere on the bezel so they don’t get lost.
STEP 2.
Insert your fingers between the LCD screen and bezel and start separating bezel from the cover.
Continue separating the screen bezel.
It might take some time to release the bezel from hinge covers. It will be even harder if the display is still attached to the laptop.
Finally, the screen bezel has been removed.
STEP 3.
The screen inverter is mounted below the LCD screen. There are no screws securing the inverter.
Remove the ivnerter board from the display assembly and disconnect cables on both ends of the inverter.
Now you can replace the inverter board with a new one if needed.
Need a new inverter board? Find it here.
STEP 4.
Let’s proceed to the LCD screen removal.
There are two screws securing the LCD screen to the mounting brackets. Remove two screws from each side.
Separate the LCD screen from the display cover.
Now you can access the back side of the LCD screen and disconnect the video cable.
Remove sticky tape securing the connection and uplug the video cable from the LCD screen connector.
Now you can remove the LCD screen and replace it with a new one if needed.
The best way to find a new replacement screen is searching by the LCD part number. In my laptop the part number is LP150X08 (A5)(N1).
You can find a new screen for you Compaq Presario m2000 laptop here for less than $100.

Steve,
Why did you replace the scree? Was it cracked?
Make sure the video cable is plugged correctly. It’s possible the cable is not making good connection with the LCD screen.

I have a Compaq R4000 (similar to ScienTux’s R4125US mentioned above). Just yesterday the screen started failing – a couple of times I was able to get the backlight on again (plugging/unplugging the power supply, pushing on the ‘lid closed’ sensor (thin rubber button on the upper right top of laptop base, near the hinge)), but then it wouldn’t work anymore. The image is there (but dim), and I can see a quick flash of light when I push/release the ‘lid closed’ sensor. Also works fine when connected to external monitor.
Here’s the question: Buying and replacing the inverter seems pretty straightforward (I’ve opened up the Compaq a few times in the past (added RAM under the keyboard, replaced a fan, etc.), and I’m willing to try that, but I don’t think it’s worth getting a replacement screen (if a bad backlight is the problem), both the cost doesn’t seem worth it anymore, plus the risk of being unable to even use an external monitor (as experienced by Steve above).
Any ideas from my symptoms as to the likelihood that it’s just the inverter? Anything else I can test to confirm/deny the cause before I shell out some money and take the laptop apart again (admittedly separating the bezel scares me a bit)? Thanks in advance!

Second question: Would you be able to email ScienTux and ask them what ’slight modifications’ to your instructions they needed to do for the R4125US? You can give them my email address so they could reply directly to me, or ask them to post it on your site. Thanks again!

ToughBook,
Most likely this is related to the inverter or backlight lamp failure. There is a good chance that a new inverter board fix the problem.
I would definitely try replacing just the inverter board first. Do not buy a new LCD screen at this point. A new inverter shouldn’t be very expensive.
Replacing the inverter and LCD screen shouldn’t damage the laptop unless you are doing something wrong.
Here’s the official service manual for Compaq Presario R4000 and HP Pavilion zv6000 Notebook PC. Just in case if you need it in the future.

Hello,
I am having compaq M2000 Laptop, and in my screen there are different colored linings are showing up and it’s annoying and spread over whole screen with vertical strips.
I got technical to review it and said I need to replace LCD of the laptop, I searched on ebay with the link you gave above, but how will I know that it is compatible with my laptop? or any compaq M2000 can work on my model?

Sneha,
Just to confirm that you have a failed LCD, test your laptop with an external monitor. If it’s just a bad screen, the external video still should work fine.
The best way to find a compatible screen is searching by the full laptop model number OR you can search by the LCD screen model number (located on the back of the screen).
