I have fixed a few laptop screens with this problem ...it is usually the lcd inverter ...somtimes if you just unplug and plug back in it may work , but usually a new one is in order .....The inverter is a small cuircut board just behind the plastic cover at the bottom of the lcd screen ....to get to it you probly need to remove the rubber protectors around the face of the screen and there are screws behind them ....not sure about your model but maby do a search for replacing the screen on it and you will get pictures that show you how to take it apart.
Hope this helps
Terry

Aspire One screen has gone dim.


Hi,
Inverter is inside the LCD Screen. Mostly at the bottom in the middle. To locate the Invertor, you have to take apart the LCD Screen by removing the LCD Frame, removing rubber pads & screws (depending upon the Model of notebook you have). Moreover, the cause of dim/ dark display could be the faulty lamp. So, I recommend that you check both the Inverter and Lamp.
Another likely cause is a bad connection of power from motherboard to the LCD. So first check the connectors/ wires for any damage before proceeding to replace Inverter of lamp.
For your convenience and idea about LCD Display, I have found a general link about CCFL replacement. Click here for detailed and graphical DIY instructions about LCD disassembly.
Make sure you take proper precaution while working inside LCD, as the inverter generates a very high voltage.


Hope it helps! Good Luck! Thanks for using Fixya!

Try going to control panel, then device manager, and try right clicking and updating all drivers that have to do with graphics or your screen. If this doesn't do the trick then try finding the display drivers manually.

How do I turn up the brightness on a HP Probook 6550b?


PLEASE RATE ME!
go to the search icon under start. search brightness. it will tell you step by step what to do.
Every laptop is different, so adjusting the brightness or contrast on your laptop may vary from the steps provided on this page. However, understanding the process of how to adjust the brightness or contrast will help you change your settings.
Most laptops adjust their brightness and other settings using the function key in conjunction with another key. For example, pressing and holding the function key (abbreviated as "Fn") and pressing the up or down arrow keys as shown in the picture below, increases and decreases the brightness.

My Hp pavlion dv 2500 laptops display screen is not showing anything but internal os starts ...........automatically whenever i starts laptop..


You most likely have a defective screen - a defective inverter or a CCFL lamp or simply the video cable needs reseating. After reseating the video cable and the problem is still there then :-
To determine if you have a LCD screen or video card problem, read this and follow the instructions.

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 or appear black.
  • 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.

HP dv9000 won't come out of black screen.


You could have a faulty video card, or a faulty inverter, (this supplies high voltage to the CCFL lamp), or a faulty CCFL lamp.

Connect an external monitor to the laptop and power it up, if you see a clear image on an external monitor, this means your video card is OK.

If you see a very dim image or flicking image on the LCD screen it means you have a backlight problem.

Monitor


Sounds like you may have a bug, you could try re-ionstalling everything fresh, it may need a driver update. Check the funtcion keys. Sometimes you can turn up the screen contrast by holding the function key and hiiting the function key that looks like a white and black sun, Black is for darkewer, white is for brighter.

Also, ost laptops when on battery power, will auto dim to save battery power.
