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.

Thanks a lot, my laptop screen hasn’t been working properly .for a while so I’ve been using an external monitor since. When the white screen appeared the external monitor stopped connecting to my laptop for some reason. I never knew I could activate it using fn + f4. Learned something new today.

Goto the catalyst program and then goto desktop management and make sure that you check the detect devices manually and not auto.
This has cleared up my white screen problem; I guess the auto detection function is messed up and that is why you get a white screen.

hi everyone, just to let you all know I had this same issue and I purchased a new LCD screen from ebay for £38. (some may say that’s pricy however considering brand new laptop’s cost on average £230,I’d say it’s a bargain!), anyway I watched a tutorial on YouTube ..got myself familiar with how to un-do and re-do the laptop up and replaced it myself ..now I have a virtually brand new fully working laptop!! I also had a button missing that couldn’t be replaced with buying a single button so I replaced the whole keyboard also so all in all my repairs where just shy of £50

It can be still an issue around the system located behind the right-bottom frame of the LCD. You could try lightly push the frame on that place using your finger while your laptop is on (and white) to see if you get picture than. Cheers

I had the same white screen death problem while i was palying a game (“monkey island”)….i simply pressed the windows key…..the screen came back to NARMAL(!) showing my desktop which was a higher resolution than that of the game….i clicked the game again on the taskbar….the game showed up well as before…..(not for long though…white screen came back soon)…..was forced to repeat this pressing of Windows key in order to bring back the high resolution desktop to my view…….Maybe it was because of a problem of “heated” graphics card !! ((eventually, i pressed the hibernate button and then resumed power a few minutes later for the G Card to cool…..No White screen of death for quite a looooong time !!! Like a Charm ! ))
so u can TRY YOURSELVES by assigning a SHORTCUT KEY to a ‘game’ or other ‘Programs’ that can run in lower resolution(u can even do that by checking the ‘Properties’ option)…so you can switch to a display other than the white screen !
This is a temporary solution but yet helps you from the burden of shutting down the computer to Escape from the ‘WHITE SCREEN of death’

hi,
i have most likely the same problem with my laptop, OS (Windows 7 Ultimate 32 bit) is working fine, its working fine with external screen or LCD monitor, i opened it and remove the LED cable then reconnect again it works fine but after in few minutes or when i make restart or shutdown and turn on again, problem come on same like before white screen, some time when i turned on… its work normally but not all the time
so its means OS is working fine, VGA and motherboard both are fine so the problem must be either LED or LED cable, any one can suggests me which thing i have to replace it ? cable or LED ?
sorry i forget to tell you about the model guys, its ACER Aspire 5742
thanks
