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.<blockquote>-
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.
</blockquote>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 [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذا الرابط] provide step-by-step laptop disassembly instructions.
