Yesterday took apart and repaired my notebook LCD screen with water damage. The screen itself was working just fine but it had two different problems.
- previous owner spilled water on the laptop. Somehow the water got inside the LCD screen and left stains inside the screen. The water marks were very noticeable on a white background and it was very irritating.
- the screen also had dust and lint inside also very noticeable on a white background. I have no idea how it got in there but I decided to clean it up too.
To fix both problems I had to open up the LCD screen. This was my first experience on opening a notebook screen. I was pretty confident because I didn’t really care if I break the screen, I just wanted to know if it’s possible to fix it.
Warning: the LCD screen can be easily damaged if you open it up. If you do something wrong the screen might become completely unusable and you’ll have to buy a new screen. It’s very expensive. Think twice before you decide opening the screen. Continue at your own risk.
Here’s my Dell Latitude D610 notebook with water damaged screen I’m going to take apart.
First of all remove the battery from the notebook.
Lift up rubber screw seals and remove all screws.
Carefully separate the screen bezel from the LCD cover and remove the bezel.
Remove two screws from the front and two screws from both sides.
Carefully remove the LCD screen from the cover and place it on the notebook base. Disconnect the video cable and the inverter board cable.
On this model the inverter board is attached to the screen with two screws. Remove both screws, disconnect the screen cable and remove the inverter board.
Carefully peel off sticky tape and foil and put it aside. You’ll have to put it back in place during the screen reassembly.
Remove two screws from both sides of the screen.
Carefully place the screen upside down on a flat surface. Carefully unglue the film that covers the circuit board and remove two screws from the board (top circles). I wasn’t really sure if I have to remove screws on the bottom, so I removed them just in case. Do not touch the circuit board with fingers.
After both screws are removed you should be able to lift up the circuit board. Be careful, it’s still attached to the LCD.
Start unsnapping the metal frame from the screen. There are a lot of latches on all sides of the screen. You can unlock them with nails or a small flathead screwdriver.
After all latches are opened you should be able to separate the screen into three pieces: metal frame, LCD and background (not sure about correct technical name).
If you have lint or dust inside the screen, probably you’ll find it between the LCD and the background. Do not touch LCD or background with your fingers. I was able to remove dust and lint up with a very soft cloth, barely touching the LCD and background surfaces.
After I split the screen I found that the background has a few some kind of optical layers (three transparent sheets) and in my case they were damaged by water. The water dried out and left stains between these optical layers.
In my case removing dust and lint wasn’t enough and I had to go further.
Very carefully separate the LCD with attached circuit board from the background.
To remove damaged optical layers it’s necessary to remove metal locks on both sides of the screen. It’s like a small clip that keeps layers in place.
After I removed both clips, I was able to look between the layers. At first I tried to clean up the dried water marks with a soft cloth but it didn’t help. The stains were still visible and didn’t want to go away.
Fortunately I had another similar screen laying around, it had a cracked LCD. I decided to borrow the optical layers from the cracked screen and transfer them to my screen. I wasn’t sure if it’s going to work, but as I mentioned before I didn’t really care if I break the screen. It was just an experiment.
So I disassembled the cracked screen and carefully transfered the white background and all transparent layers to my screen.
After that I assembled my screen back removing dust and lint with a very soft cloth. Breathlessly connected my new screen to the notebook. Turned it on and…
That’s a miracle, it works!
No dust, no lint, no water mars inside the screen! It’s clear and the background is absolutely clean!
My donor screen had a cracked LCD but it had a good working backlight tube. The backlght tube is very fragile and it’s located inside a metal casing. I didn’t remove the backlight tube, I just broke off the entire metal casing from the plastic frame. I’m going to use this backlight tube for testing purposes.
If you fixing a Dell laptop yourself, probably you’ll need a service manual. Some Dell service manuals provide step-by-step laptop disassembly instructions.
Are you looking for a new screen? You can find very inexpensive brand new LCD screens here, just search for your laptop model.

Fazel,
I think there could be a problem with the hard drive. Run test on the hard drive, you can use Hitachi’s drive fitness test.

Don (comment 262),
Sounds like a problem with the LCD screen, apparently the backlight lamp is dying. That’s my guess.
I don’t think that your problem is related to the inverter. From my experience, when inverter fails, the entire LCD goes dark, not just a part of the LCD.
Most likely there is only one backlight lamp. The backlight lamp is located INSIDE the LCD screen on the bottom and it runs horizontally. It’s possible to replace the backlight lamp yourself as I posted here:
How to replace laptop backlight lamp (CCFL)
But it’s very difficult. If you have no laptop repair experience, most likely you’ll make it worse and damage the LCD screen, so proceed on your own risk. I would suggest replacing the LCD screen.
I’ve seen backlight lamps like that, when one side is brighter than the other one.
The only reliable way would be testing the laptop with another LCD screen.

Oliver,
You cannot fix the ribbon, you’ll have to replace it with a new one.
From your description it sounds like there is a problem with the LCD screen, not the ribbon cable. That’s my guess.

Harsh Kulkarni,
Sounds like a problem with the LCD screen. There is no easy way to fix it. Call HP customer service and fix it while the laptop is still under warranty.

I have a 2 1/2 year old Dell Inspiron E1705 with an XGA+ (also known as WXGA+?) display. For the past few weeks when I power the unit on, the screen looks normal. But, over the course of the next 20 minutes or so, about 1/4 – 1/3 of the screen (on the left side) dims. It never gets really dark, but it’s definitely dimmer (and harder to see) then the rest of the screen, which looks normal. The transition in brightness is gradual – there’s not a clear “line” separating dim from normal. The image is otherwise fine – just dim in that section of the screen. I have an external monitor connected to the laptop and the image is fine, so I think that rules out a video card problem. From reading the above (great info by the way), it doesn’t appear to be an inverter problem either. It think (but am not certain) the display for this laptop has one backlight bulb. If that’s the case, where is the bulb located? Does it run horizontally or vertically. If it’s horizontal, can part of the bulb go bad? What does it sound like the problem might be, and how should I troubleshoot it to determine whether or not I need to bite the bullet and get a new display?
