Hi..
Your problem are related with my laptop problem, but i
totally fix it with my own. From my experience I can tell that this
problem may be related to the
following:
1. Loose connection between the video cable and the LCD screen.
2. Defective LCD screen.
3. Defective motherboard (I assume the graphics card is integrated into the motherboard).
Here’s an example of a laptop with white screen. When you turn on
the laptop, it starts but the image on the screen is completely white
right from the beginning. In my case it was a Toshiba Satellite M45
laptop but this problem may occur with any other brand.
Most likely you still can use the laptop with an external monitor.
Just connect the monitor to the VGA port on the back or side of your
laptop and then switch the video output from internal to external mode.
On Toshiba laptops you can toggle between internal and external screens
using Fn+F5 keys. Hold down Fn and press on F5 until you get video on
the external monitor.
On IBM laptops use Fn+F7.
On HP laptops use Fn+F4.
It’s possible that you have to use a different key combination on your laptop but you get the idea.
On some laptops, in order to be able to use the external monitor, you
have to connect it to the laptop and then restart the laptop so thThe LCD screen on my Hewlett Packard Pavilion has - 3-video-cable.jpgor is detected by the laptop.
I noticed that in some cases the laptop screen may turn white
because of poor connection between the video cable and the LCD screen.
If you want to check this connection, you’ll have to take apart the

LCD screen.
I always check the video cable connection first. Reconnecting the video cable may fix your problem.
The best way to find out witch one is causing the problem is testing
the laptop with another working LCD screen. Without this test you’ll
have to guess because as I mentioned before this could either bad
motherboard or bad LCD screen.

(connector 2) and the inverter board (connectors 3 and 1). After that
you connect another working screen and test video.
For this purpose you using one of my test LCD screens. My test
screen is cracked and because of that you see a wide white bThe LCD screen on my Hewlett Packard Pavilion has - 7-white-lcd.jpgter but it still works fine for this test.
The original screen is white but my test screen works normal (except
the crack of course) and I can see the image. After this test I can
tell that the problem must be related to the screen.
After I'm assembled everything back together and connected the original LCD, it’s still white.
In my case this problem is related to the LCD screen and it has to be replaced.
That's
my laptop brand and model, and i am searching an image regarding about
my problem. This problem are common to another brand.
Hope it may helpful for you! Thanks for using fixya.
Good luck
