HomeThis guide explains how you can remove and replace LCD screen, video cable and inverter board on Dell laptops. These instructions should work for most Dell laptops and will be very similar for many other laptop brands.
Example 1. The inverter board is located under the LCD screen.
On this example the display panel had been disconnected from the laptop. It’s not necessary to disconnect the display panel in order to take it apart, you can take it apart while it’s still connected, just do not forget to unplug the AC adapter and remove the battery.
Remove three rubber screw seals on the top and two plastic screw seals on the bottom of the screen bezel.
Use a sharp object. After all five (or more) seals are removed, you can remove screws located under the seals.
Separate the screen bezel from the top cover with your fingers. There will be many plastic latches holding the bezel and the top cover together.
After all latches have been unlocked, you can remove the screen bezel.
Remove four screws on each side of the display panel. These screws secure the LCD screen to the display hinges.
Carefully lift up and remove the LCD screen. Place the screen upside down on your desk.
Now we are going to remove the video cable. Unplug video cable from the LCD screen and from the inverter board.
Remove and replace the video cable.
You can search for a new video cable by the part number located on the old cable, just google for it.
Alternately, you can search for a new video cable by the part number located on the connector.
Remove two screws securing the inverter board to the LCD screen. One screw is marked with the red circle, another one is pointed with the red arrow. Disconnect the backlight lamp cable from the inverter board.
Now you can remove and replace screen inverter. You can search for a new inverter by the part number located on the old inverter.
Example 2. The inverter board is located beneath the LCD screen.
On some Dell laptop the inverter board is located beneath the LCD screen. Before you can remove the inverter, you’ll have to remove the LCD screen as it explained in the first example. Then remove two screws securing the inverter board (marked with red circles) and unplug the CCFL (backlight) cable. Now you can remove and replace the inverter.

Hello, I have an advent monza c1, my son stood on it and it wouldnt start. i thought the motherboard was broken but iused a hdmi cable to connect to my television and it works.
i took the laptop apart and put it back together again, now two thirds of the screen works perfectly but one third of the screen is just white.
Do you think this is the inverter or a damaged screen?.
Thank you.

What if I want to hook up a second LCD panel as an “external” monitor? Is there a way to, if I have a working second LCD panel and inverter board, connect it to the VGA or Digital video port somehow to turn it into a second screen? (I have a DELL inspiron 9400/e1705)

Dell Inspiron 9400/E1705 (PP05XB): top one third of LCD screen displays properly while bottom two thirds of LCD screen is black. External display is fine….Dell video diagnostics pass without error. Bad LCD?

Bogdan,
Sounds like backlight lamp failure. The backlight lamp is mounted inside the LCD screen and very hard to replaced.
When backlight fails, I suggest replacing the whole LCD screen.
This guide explains how to replace LCD screen in Dell Inspiron 6000 laptop.
Here’s one suggestion. If you decide to replace the LCD screen, buy one which comes with inverter board installed.
If you install a wrong screen (not compatible with the inverter) the brightness will not work properly.
I found that with Dells it’s always better to replace LCD screen with inverter together.

Hello,
One of my laptop Dell Inspiron 6000 is having problems. When i boot the machine the screen is on just for 5 seconds and is more like red/pinkish, after that is black. If i look closer i can see that the LCD is working but there’s no light. What could be wrong? Please help me

Maria,
The video cable has to be plugged into the socket, not just touch the socket. Why are you asking? You cannot plug it all the way into the socket?
Take a closer look into the socket on the LCD screen. Does it have a row of very thin pins? Make sure there are no bent pins inside the socket on our new screen.
Again, the video cable connector has to be plugged in.

carrol,
It’s not the inverter problem, that’s for sure. You still can see the screen, so the inverter and backlight lamp work fine.
It’s either bad LCD screen (more likely) or failed video cable (less likely).
Can you get image back to normal if you torque the screen a little bit? If yes, this is bad LCD screen.
