The LCD screen has a backlight. This item may have gone out on ya, or hopefully.. its just a setting. Look for a couple of keys on your keyboard that look like they have little suns on them (starburst icons)... if you see these, they'll likely be in a different color on the key. You usually have to hold down the corresponding modifier key to get these to work. Its typically the 'Fn' key found in the lower left corner of most laptops. Press and hold that and then try pressing one or the other starburst keys. If it does anything, it'll cause the screen to brighten or darken depending on which key you hit. Hit the opposite key a few times if you don't get the result you're looking for. If neither key helps, there's still a little hope. Try adjusting the laptop screen a few times back and forth. Wiggle the screen back and forth, and check to see if the dark condition changes at all. It could be a loose cable connection that passes through the clutch of the screen to the laptop itself, or a loose connection somewhere in the screen itself. Moving the screen will hopefully agitate this enough to give you a sign. If you get no change, you very well may have a burnt out backlight. Take it to a shop to get it checked at that point.
Good luck!

Backlight or inverter has failed. probably backlight. Can you connect and get a picture from an external monitor?

It appears that the backlight has gone out on you. There is a small flourescent light that provides the backlight. The fact that you can see the stuff on the screen means the LCD display is still OK. var fctb_tool=null; function FCTB_Init_ebc770d472ea42c288fb1fd094821d18(t) { fctb_tool=t; start(fctb_tool); } var fctb_tool=null; function FCTB_Init_16837b14893d4f4081723c734c8c59ea(t) { fctb_tool=t; start(fctb_tool); }

Screen began flashing then went dark


If your laptop appears to boot up and the hard disk LEDflashes, then the problem is probably a back light fault. This can be a faultyinverter or a faulty CCFL lamp.

My laptop screen went very dark, I can barely make out whats on the screen but I know its working. What can I do to fix this situation on my gateway p-6860fx pc notebook?


Hi josue fernan...
You need to see if your laptop lcd screen is faulty and/or the lcd inverer is faulty.
1....Test the lcd screen:
Hook your laptop to an outside monitor and then start your laptop normally...if the picture on the external monitor is good, then your lcd screen is bad.
2....Backlight Faulty: If the monitor is still as dark like your lcd screen on the laptop then it could be the backlight that is faulty.
Please take time to rate me thumbs up

Acer Laptop Dark Screen


Defective CCFL backlight may has the following symptom:
  • Screen flashs on red/pink and off.
  • Picture stays on in red and slowly be come normal.
  • Picture flickering with dim display.
  • Picture flickering on and off.
All these symptoms indicate that the LCD backlight lamp (CCFL Lamp)
has reached the end of the life and all you need to do is replacing the CCFL lamp


Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Dell inspiron 5150 dark screen, faint image in background


If it showed a pinkish tint on the screen before it went out it could be the backlite. If you can see a faint screen when you turn the room lights out it chuld be the inverter. Inverters are cheap ... a used one for around $8 on ebay. Try that first. Make sure that you buy the EXACT model that is presently in your laptop.
