Inverter, backlighting, the switch that controls the on/off of the display when the Lid is open or closed. Did you replace the screens? Take a look at this video, it may help you troubleshoot: http://www.youtube.com/watch?v=2Yi6GNFcP3w

SOURCE: screen is white, no picture

I just fixed this problem on my Toshiba Satellite. I had to take the screen apart. There are 4 scews on the corners that remove the front tim. (sometimes they are covered by rubber bumpers)

This will usually expose more screws to remove the back of the LCD screen. Follow the ribbon cable up the back of the screen to where it plugs in to a circuit board.

The problem for my laptop was the cable had come un-seated from the circuit board. I push it back in and the display worked.

Note... the cable did not look un-plugged;
becareful not to touch the top of the display where all the wires from the circuit connect to the LCD display;
You may want to add some tape to the cable to keep it in place. There was some there but it was working well.

SOURCE: Laptop Screen faded white

There are a couple of possibilities.

1. A cable has come loose inside the computer4.gif.

2. A cable has become defective.

3. The LCD is defective.

If you wiggle the LCD back and forth and you can get the picture to work again intermittently then answers 1 & 2 above would be more likely.

SOURCE: My laptop display only shows half a screen. The

i have solve the problem for my hp nx7300. mine used to show everything that should be shown on the screen but had the screen placed in a Conner so small. i solved this by uninstalling the monitor and unknown device drivers. i have then installed the unknown device as a blue-tooth adapter to avoid this problem recurring. hope this sorts out some people's problem. the other half screen with half completely not shown has to do with the cable connecting the monitor and the CPU. remember solving this for my friend by cleaning the connection port.

Laptop white screen


Having a laptop screen turn white is one of the most frustrating problems a user can experience since it prevents use of the laptop to find a solution.
A white laptop screen indicates a serious problem with the laptop's hardware, and no easy solution to this issue exists.
Just diagnosing this condition requires advanced computer knowledge.
Identification

With this problem, the laptop itself will power on and load the operating system as per usual, but the screen will become a complete, static white, according to LaptopRepair101.
No particular brand or make of laptop falls prey to this issue more than any other; it can happen to any laptop.

Causes
Since so many different brands and models of laptops exist, specific causes of a white screen vary from laptop to laptop.
The likely cause in most cases of a white screen on a laptop is a connection problem between the LCD screen and the video cable running from the motherboard.
The issue can also reside strictly with the motherboard or the screen might contain a defect.

Considerations Users can diagnose a white screen problem by opening up the laptop display case to determine whether a loose video connection on the back of the LCD screen exists.
Reconnecting the video cable should resolve the white screen; a video cable reconnection that does not fix the white screen narrows the root cause to a problem with the motherboard or the screen.

Motherboard Problems
The only way to determine if the laptop screen turns white due to a motherboard problem is to test out a different, working LCD screen with the laptop.
This requires the user connect the inverter board--the power supply for the LCD backlight and the video cable to the test LCD.
If the test LCD works with the motherboard, then the laptop's screen needs replacing; otherwise, a new motherboard is needed because there is no way to replace an integrated graphics card on a laptop motherboard.

Prevention/Solution
Taking apart a laptop screen may make some users feel uncomfortable, so you can use an external monitor connected to the VGA port common to most laptops if the processor and hard drive still work fine. Using an external monitor requires finding the proper function key command to toggle between the LCD and external monitor.
Warning
Taking apart the LCD screen on a monitor likely voids any manufacturer's warranty.
Consider visually checking the video connection to the laptop screen as a last resort if no other viable options exists.
The service manual that came with your laptop likely offers some tips to disassembling the computer, or conditions that could void the warranty.

Everytime I open my laptop the screen turns white and i have to work with it 3 quarters of the way closed for the screen not to be white


A white screen indicates that the video data cable is not connected. Either the cable is coming loose when you open the screen or there is a break in the cable. Someone will have to open the case to find out which.

The screen is white >>>


Your inverter board is OK otherwise you will not get any light on the screen, there is only one inverter board, Check the flat ribbon cable connected to the LCD panel (locate behind the LCD panel), when this connector comes off you will get white screen.

White Screen Issues on Toshiba M115-S1061


connections could be good in ribbon cable
but still needs to be replaced

the white screen indicates that the inverter is still good
if the laptop works with desktop monitor, then video card is good
if you tap the lid to the lcd and it goes on and off ,ribbon cable for sure,
everytime you open and close the screen , it tugs on the ribbon cable also , only tape holding this in place

Purchased a Acer Aspire 2930z. i get a blank white screen.


Connect an external monitor to your laptop and power the laptop up, if you get a normal image on the external monitor then you have a faulty LCD screen and may be replaced. If you still get a white screen then you most likely have a faulty video card.

The video card is part of the motherboard and usually cannot be repaired, the motherboard is normally replaced but it may not be cost effective to replace. If the laptop is a several years old then it is time to get a new one.
