Most likey, bad news im affraid, its the screen just going bad. Usually theres nothing that can be done. You can try reseating the ribbon cable and see if that improves it, but most likely it wont, they usually have only so many operating hours before the crystals or plasma goes out, depending which it is. Plasma usually goes out quicker than LCD.

Try finding a replacement on Ebay or online somewhere.

Good luck.

P.S. im asuming of course that you know a little about what you are doing and it isnt something like the display settings or contrast.

Hello !

Since an external monitor works, it is the display's backlight or inverter board.

If you were experiencing discoloration in the screen (pinkish lower light hues) before it failed, that would indicate a CCFL backlight issue. If the screen suddenly went dim rather than a slow degradation, the inverter would be indicated.

In either case, a technician in your area should be able to help. Evaluate to see if the repair is cost-effective.

Hope this helps.

Yep, it's the inverter. Anytime there is a red or pinkish tint or hue you know it is the inverter. Usually the inverter is very easy to change. I would buy one on eBay for your best price...

Dull laptop screen back light


You may have a faulty CCFL lamp. A faulty CCFL lamp may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering and/or with dim display or appear black. Picture flickers 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 replace the CCFL lamp.
To determine if the video card or the LCD is faulty, connect an external monitor to your laptop and power the monitor up first then the laptop, 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 or a faulty inverter that supplies high voltage to the CCFL lamp. Usually the CCFL lamp fails before the inverter.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

If the laptop appears to boot up and the hard disk LED flashes then you have a backlight problem.
