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.

My pc desktop is showing a white screen when its on what should i do?


Is it an LCD monitor ?

When an LCD screen has turned completely white, there are three normal causes: the screen is defective, the video cable is not connected correctly, or the graphics card on the motherboard of the computer is faulty. You will need to troubleshoot these possibilities to determine which problem you have. If you are not experienced in working on computer equipment, you should not attempt to disassemble your LCD screen because you could easily damage it. Seek professional assistance unless you have experience working on computer hardware.

Disconnect the white LCD screen from the computer by unscrewing the blue monitor cable. Connect the working LCD screen to your computer by attaching its blue monitor cable to the same slot. If your computer display does not show on the functioning LCD screen, try rebooting your computer. If it still does not display, the problem is with your computer's graphic card on the motherboard. Seek professional repair assistance. If your computer display shows normally on the working LCD screen, proceed to Step 2. Unplug the LCD monitor with the white screen. Disassemble the rear panel of the monitor with the small screwdriver. Carefully separate the screws into piles so that you can keep track of how to reassemble the monitor. Locate the internal video cable, a gray cable with a plug on the end that connects to the main components of the screen. See Below for the References section for photos of the video cable for assistance. http://www.laptoprepair101.com/laptop/2008/04/13/laptop-lcd-screen-turned-white/ Unplug the cable, checking for any debris or blockage. Reconnect the cable firmly. Reassemble the LCD screen. Plug it in and connect it to your computer. If the screen is still white, you have a defective LCD screen. You will need to replace it or take it to a professional repair service for assistance. Hope this helps.

No white screen


I'm happy to try to help.. But 'no white screen' is kinda cryptic. Is this a PC, running Microsoft XP, is the white screen to do with a program you are trying to use?
