Internal screen is white

Is it a touch screen? Has it been dropped at all? If so, the internal screen could be busted. Sometimes the touch part will still work itll just be a blank screen though. You may need to order a new internal lcd screen.

This issue is due to the malfunctioning of the screen or due to any other internal hardware malfunctioning of the notebook.

To further isolate the issue, I request you to connect the external monitor and check.

Once after connecting the external monitor, please tsp Fn+F3 Switch between the display and external monitor in the following order:

Display
External monitor
Display and external monitor

If the external display is fine then the issue either could be due the malfunctioning of the display cable connector between the screen of the notebook and motherboard or due to the malfunctioning of the screen.

As this the hardware issue, Please contact the nearest repair center to get it resolved.

Your display problem may be in the graphics controller on the motherboard. It might also be in the display itself, which contains a lot electronics. Yet another possibility is that the system is freezing up completely, and the white screen is the result.

Since it takes a while for the screen to go white, the trouble is most likely due to something heating up. I've fixed a lot of laptops that freeze up because the processor chip overheats. Sometimes it's because the fan isn't working, or the screws holding the fan assembly down work loose.

Hook up an external monitor to the laptop for testing. You might need to enable the external VGA connector with a function key before you'll see anything. If the motherboard is freezing up, the external monitor will quit as well when the laptop display goes white. If the computer keeps working normally with the external monitor, though, you know the trouble is in the graphics circuitry or display.

Unfortunately, it's hard to say for sure whether the motherboard or display is at fault. My experience has been that a completely blank display is usually a motherboard failure, but not always. Failures in the display itself usually cause lines or other problems with the image, but you still see something.

Replacement motherboards are often available at reasonable prices, but displays often are not. You may want to take this computer to a service shop and let them figure it out and give you a repair estimate. That way you won't wind up buying a part that may be costly and not fix the trouble.

I hope this helps you decide what to do. Thanks for using Fixya!

Laptop LCD screen turned completely white
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).
When you turn on the laptop, it starts but the image on the screen is completely white right from the beginning.
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.
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 which 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 and the inverter board. After that you connect another working screen and test video.
The original screen is white but my test screen works normal 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.

i think flexible wire was damage,replace it

same problem, broke my screen, ordered a new screen off ebay and replaced it. now it works fine most of the time but sometimes external display freezes. sometimes goes black, sometimes goes multicolor pixelated (full screen, in blocks, or lines) when this happens sometimes touchpad still works, others not. removing battery usualy temporarily fixes.

It seems to be ur lcd stops working..Take this to service center...

Am I correct in understanding that your MacBook is operating properly, but when you attach your external monitor it doesn't show anything?
I often connect my black MacBook 2GHz to my flat screen's VGA port. Sometime the screen doesn't respond for one reason or another. The fastest solution is typically to mirror the screens then return to normal. When that doesn't work, it's usually enough to restart the MacBook while it's still plugged in to the external monitor. If neither of those work, try connecting to a different monitor or finally try replacing the connector.
Unfortunately those connectors don't have the best life spans. (See Apple's customer reviews on DVI connectors.)
