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.
In one of the previous posts I explain how to remove and replace the keyboard in a Dell Latitude D620 laptop.

@ Lisa,
Most likely the backlight inside the LCD screen is damaged. If that’s the case, you’ll have to replace the screen.

I connected the laptop to a monitor and the laptop works fine.

My daughter dropped her Dell latitude D620 and now the screen is black. i pressed a key (not sure which one it was) and the Desktop showed for a split second. Does that mean that the screen is still ok or do you think I need to replace the screen?

@ Eric,
No, that wouldn’t make a difference. As long as your new screen and inverter connected to the motherboard it’s not necessary to assemble the laptop completely for test.
If we assume that new screen and inverter are good, your problem could be related to following:
1. Bad connection between the video cable and screen/motherboard/inverter.
2. Failed video cable.
3. Failed motherboard. Could be just bad video connector on the motherboard.
Sorry, I cannot tell what is wrong without testing the laptop with known good parts.

Hi there! Maybe you can help…screen on D630 went black, but monitor worked in docking station. Replaced screen and inverter, but screen is still black. I didn’t completely reattach it (put all of the screws back in) to test – would that make a difference? Both cables were attached, tho. made sure to order a WXGA replacement. There was one difference – the cable on the old screen (to the inverter) had a W on it, and the new one has HBFI. Any ideas? TIA for any thoughts!

@ Lewis Fulk,
Does it still work fine with the docking station?
Also, test the laptop with an external monitor. Can you get image on the external monitor?
Look on the docking station connector on the bottom of the laptop. Can you see damaged pins in there? Maybe something got stuck inside the connector?

My Dell Latitude D620 was working fine and then I connected it to a docking station for a couple of weeks. When I disconnected from the docking station the screen now shifts slowly through white, yellow tint, green tint, blue tint, etc. It doesn’t display any information at all. Would this be in the inverter, the LCD, or maybe a cable problem. That it quit working at the time I started using the docking station may be a coincident. Would like to know if anyone else has experienced this problem and what was done to fix it.
