I like the way this is written out so much, I am just going to give you the link,

http://www.howtofixbluescreenofdeath.com/ati2dvag-blue-screen/

Yes, call it cheating if you will, but the written 'prose' on that page, goes way over whatever 'chicken scratch' I will type out.

Works? Appreciate it if you would let me know in a Comment.

Rate this solution if it works? Naa. Wasn't my advice.

Will not come on, the lights come on but the screen is still black


This sounds like you have bad capacitors on the power supply board. Look for bulging capacitors. Any weak capacitors will have a bulge at the top. If you know how flourescent lighting works with a ballast, tv's work the same way to power up the backlights but use capacitors. The backlights when lit allows you to see the picture. If they are not charging up fully you get a black screen or a very dim screen which looks black under normal lighting conditions. Sometimes you can turn off all lights and maybe see a faint picture.

Back light or inverter. my screen is black.


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

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.

Dark screen


try this, on the laptop keyboard on the bottom left cornet, there should be a button that says 'Fn' written in 'blue'

also on the keyboard, there are secondary buttons, if you look on some off the buttons on the keyboard, there are some pics, numbers letter etc written in blue on the buttons, look for one that has a arrow up and beside that on the same button a picture of a sun, when found do this:

Hold Fn and click on that key with the arrow pointing up with picture of sun and tap that button repeatedly to increase back light while holding the Fn button down firmly

Not really that tough. Sounds as though the backlight is shutting down, either from a power supply failure, or a failure of the backlight circuit itself. You can verify this by holding a flashlight to the screen in the area where the menu usually appears to see if it displayed on the LCD panel with no backlight. If you can faintly see the menu displayed, your backlight has shut down and the most likely cause is the backlight inverter board, followed by the power supply and the backlights themselves which are part of the LCD panel. If you found this information answered your questions, please be sure to rate it. Thanks!
