Dim screen for laptop LCD screen

We have all ran into a problem where you go to turn on your laptop and the screen turns very dim to where you can barely see the picture.

Alot of times the LCD cable the one that goes from the LCD to the motherboard becomes loose. If you see it loose or not, unseat and reseat the cable at both ends.

You should at this point have video. If you don't then its either going to be a problem with the LCD or the inverter.

Good thing is when you replace the screen the inverter comes with it so you'll definitely be able to fix the problem either way.

What's your problem?the screen turns very dim to where you can barely see the picture


Your monitor is going bad or your video card is going bad. Try using another monitor on the computer to isolate the problem. Borrow a monitor from a neighbor, friend, relative or co-worker and see if you can barely see the icons and desktop on it. If the borrowed monitor is bright and clear and you can see things ok, then your original monitor is going bad. If the borrowed monitor shows the same problem of barely being able to see things, then your video card in the computer is bad.

i cant get the color right. its to red??? any help? i did notice with the back cover off, there are 6 adjustment screws


yes! those are the screen and focus adjustments. 3 for screen, 3 for focus. try this. go in menu....turn down color, brightness, contrast all they way down. you should then have no picture, but in your case a little red. then go to back of tv and turn those 3 screen adjustments all the way down. slowly turn the screens back up until you get barely a picture. because remember, your brightness and contrast is all the way down. the picture should be dim but seeable and with red, green, blue adjustments, make it a black and white picture. when balanced..... turn up color , brightness, contrast in menu. enjoy!

The screen is black.


either the backlight/inverter has died/dying or less likely if it has been roughed up, the ribbon cable to the screen may be loose.

monitor very dim


You could have a faulty inverter but
You most likely have a defective CCFL backlight, it may have 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.
