What can you do if the laptop LCD screen turned completely white? 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 the external monitor 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 display panel because the connector is located on the back side of the LCD screen.
These laptop service manuals and disassembly instructions may be useful.
I always check the video cable connection first. Reconnecting the video cable may fix your problem.
If reconnecting the video cable doesn’t help, most likely you have a problem either with the LCD screen or with the motherboard.
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.
You’ll have to disconnect the video cable from the 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 I’m using one of my test LCD screens. My test screen is cracked and because of that you see a wide white band in the center 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 assembled everything back together and connected the original LCD, it’s still white.
CONCLUSION. In my case this problem is related to the LCD screen and it has to be replaced.

Anne,
I think it depends on the laptop brand and model you have. On some laptops you can toggle in BIOS, in other laptops you have to wait until it boots into Windows.
I was working on a Toshiba laptop. This particular model detects an external monitor automatically.
1 pixel vertical lines? Sounds like a problem with the LCD screen.
Can you find an external screen and try?

Hi,
When you connect an external monitor and use the function keys to toggle, does this work before logging into windows? I thought you would have to be logged into windows for the function keys to work but from your photos it looks like you have the boot sequence showing up on the external monitor….laptop in my case is a HP Compaq M2045.
It hasn’t got a white screen but it has developed a thin vertical line an inch in from either side of the screen which is various colours depending upon the background colour. Thinking it might be the cable or possibly screen, but getting an external monitor would be cheaper than replacing the laptop screen…but if the screen eventually dies completely, would want to know that the external one will work without needing to get into windows first…

john,
To me it looks like you have a problem with the LCD screen.
In order to confirm that you’ll have to test your laptop with an external monitor attached to the VGA ports. Can you get video on the external monitor?
If you can, most likely it’s bad LCD.
You might have to use Fn+F8 key combination to switch video from the internal to external mode.
Before you replace anything, test the laptop with an external monitor.

PLEASE HELP ME, I DO NOT KNOW WHERE TO TURN TO….
HERE i made a video of it so you guys can see clearly :

THE main PROBLEM: OK i have an inspirion 1520 with 8600mgt. i was playing a video game but then my graphics drivers crashed, so i went to start> shutdown and i restarted the computer. when i turned it on again everything was ok so i turned on the game again. this time graphics driver crashed again but this time i had to shut down by holding down the power button for 10 seconds. now when i restarted the computer, the screen is BLANK AND BLACK, nothing shows up..no bios boot page, no windows logo, nada. i reckon that the system still runs b/c i can still hear the windows sound when i log into my account (yes i logged on blindly). also i can turn up and down the brightness, but i just can’t see anything, CAN ANYONE PLEASE HELP ME? i update my computer regularly and had the newest bios, i was running windows xp sp3/
ANOTHER PROBLEM: so alot of people from other forums are saying its my gpu, but here is the other problem, MY DELL WARRANTY EXPIRED. is there any way for me to replace my 8600mgt with another 8600m gt? i can’t send it to dell cause my warranty expired. i looked at the online manual and it seems like you could take out the 8600m gt on the inspiron 1520 with ease, but my problem now is finding another 8600m gt that is compatible with dell. i’ve googled and found nothing, DELL does not have one neither. does anyone know any place where i can get another 8600m gt card and remember my comp gpu is not mxm. anyone know any sites?
my DELL WARRANTY EXPIRED 5 MONTHS ago, is it possible to still extend my warranty? i haven’t played my laptop the whole before it crashed. i only turned it on for 30 mins and i noticed that it was running hotter than usual and i checked the temps and noticed that the 8600m gt gpu was really hot, THEN BOOM NOW I CAN’T SEE ANYTHING ON MY COMPUTER. PLEASE HELP PLZ.

I have a compaq presario 1500, the monitor is white but works with a external hooked up. How do I fix this problem? I see someone fixed it but was still white and the screen needs replacing. But I need to make sure if it can be hooked up on the inside first. This would help very much. Thank you for reading this.

Hi,thanks for useful site.
I have a Sony VGN-S150 laptop. One day when i pressed the power button, the screen went “white” (gray-bright actually)and held there,HDD still running, nothing else, and my laptop could not start, even the boot logo.
But the interesting thing is, when the laptop not responding, if i turn off (by press-n-hold power, wait for HDD stops) and then turn on immediately, it will work as normal ( boot, starting windows,…), but the screen gets white again if at screen saver mode (turn off display).
What could be the problem?
I really need help. Thanks

My T-60 has a white screen. Hooked up to external monitor, everything fine. Bought a new screen, still white. Bought new cable, still white.
Could it be inverter? Can’t think of any other possibility.
Stumped on this one.
Thanks for any help.
