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

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.

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!
Dina

Susanna,

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

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