In this guide I explain how to remove and replace the LCD screen in a Dell Latitude D620 laptop.
The LCD screen removal steps will be very similar for many other Dell laptop. If this guide works for your laptop, please mention the model number in comments after the post.
If you need a new LCD screen or inverter for your Dell Latitude D620 laptop, you can find it here for about $70-80.
STEP 1.
There are six screw seals on the LCD screen bezel. Remove all six seals and screws found under them.
You can remove the screw seal with a sharp object or small flat head screwdriver. The seal bottom is sticky. Glue all screw seals somewhere on the screen bezel so they don’t get lost.
STEP 2.
Start separating the screen bezel from display cover with your fingers.
STEP 3.
Remove the screen bezel.
STEP 4.
Remove six screws securing the LCD screen mounting brackets to the display cover.
STEP 5.
Separate the LCD screen assembly from the display cover and place face down on the keyboard.
STEP 6.
Now you can access the back side of the LCD screen and video cable.
The video cable has two connectors. One of them is connected to the inverter board and another one to the LCD screen.
STEP 7.
Disconnect the small connector from the inverter board.
STEP 8.
Disconnect another connector from the LCD screen.
STEP 9.
Remove the LCD screen assembly from the laptop.
STEP 10.
If you are replacing the LCD screen, you’ll have to transfer both mounting brackets to the new screen. Each bracket is secured by a few screws.
In Dell laptops the inverter board is attached to the bottom of the LCD screen.
Even though it looks like the inverter board is a part of the LCD screen, it’s possible to remove the inverter and replace it separately.

@ Nana,
It’s hard to tell what is wrong. Maybe the problem is somewhere inside the display panel?
You can try reseating the inverter cable. It’s shown in the step 7.

After removing the keyboard to install memory my Dell D620 monitor now goes dim, flickers and goes dimmer. I can still see my desktop and read it if I’m close. Could a connection be loose? What should I look for under the keyboard that would affect the backlight? The Fn + up arrow does nothing. If I tap the top of the screen it gets bright again. It’s like it goes into hibernation or dims like it’s on battery power.

I have a Dell D620 laptop with a broken screen. I purchased and received a replacement on Ebay however it doesnt work properly. I think it has 900 pixel vs mine has 800. It fits fine but there are many veritical lines that are black and has poor visual quality. Is there a way to resolve this with a driver? What other D series laptops are compatible and will work? How can I determine if a replacement screen is 800 resolution without mechanically pulling it out? Thanks in advance for any help.

After doing a CPU and MEMORY upgrade my LCD screen went out. There are 2 very tiny connectors inside the case and one of them came loose, after re attaching the cable nothing happened…how would I go about testing and repairing this problem?

noor,
I don’t think it’s possible.

I have a dell latitude 100L’s L C D I need to know the cable connection configuration of it, and I want to use it as a vga monitor.

Art,
If we assume that your new LCD screen and inverter are good working parts then your problem could be related to the LCD cable or motherboard.
I cannot tell which one is failing.

I have a D630 that went dark a week ago. Worked perfectly fine with an external monitor but the screen was very dark such that you can barely make out the contents and only when there is ambient light. I ordered a replacement LCD/inverter from Dell for $130 and just replaced it using your excellent instructions. Thank you. However, the screen is still the same. What could be an alternative problem?
