This 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.

My computers LCD is only half lit is the inverter the problem or should I go buy the whole screen?

Susanna,
Does it mean that one side of the screen (left or right) is completely black?

Hi,
For a week or two, one-third of my screen was fairly dark — not completely black, I could still see what was on the screen in that area, but it was much more difficult to see. Just yesterday, my whole screen would very suddenly go dark. I could see that the laptop was still working, but I could barely see what was displayed on the screen. When booting up, the screen worked fine, but after being on for a minute, the entire screen would just suddenly go dark. Now, the screen goes dark immediately, even while the laptop is still booting up. Is this a problem with the inverter or the LCD screen?
Any suggestions/advice are much appreciated!

That sounds like the backlight is dying. You’ll need to replace either the Cold Cathode Fluorescent Light (CCFL) tube at the bottom of the LCD panel or the Inverter that powers it.
Replacing the inverter board is usually easy — Just follow the directions given above. From what you described it’s possible that the CCFL tube itself is burned out, and that requires opening up the LCD panel itself and doing a little soldering. A replacement CCFL or inverter will run you about $10 or so, but if you don’t feel comfortable with a soldering iron then I would suggest getting some help with replacing the tube. It’s not that difficult, but if you mess it up you could ruin your LCD panel instead of repairing it.

Hello, I have a Dell Inspiron 1720 and for the last week my screen has been randomly blacking out. If I restart the computer it usually fixes the problem but not always. At times, I can still see what is on the screen but it is very dark. Today I noticed that the 3 inches on left side of my screen are getting darker. I also noticed that is happens more often when I am running on battery power vs being pluged into the outlet. It seems like a very similar problem to the one above. What do you recommend I replace and where do you recommend I buy the parts from? Thanks Aaron

I have a Dell Inspiron 6000
For a long while now, my screen has flickered to a completely white screen.
All I had to do was push the video cable back into the motherboard, and it was fine.
Now, the screen is totally black and I can’t fix it; the video cable is kind of coming apart, so I’m pretty sure that’s all I’ll need to fix it. Am I right?
