My I pad lost the colours and turned white and blak how can I fix it


  • Hi, have you activated the Reverse colours function? Go to Settings / General / Accessibility / Invert Colours
  • did you drop it by any chance? My boy dropped his and we got the dreaded black screen one time - then we gave it the hard smack treatment on the backside to release the jammed accelerometer - this worked perfectly the 1st time it happened, the 2nd time he dropped it we reverted to strange black and white colours, the smacking continued, and the colours came back.

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.

When I put the laptop to sleep, it won't turn on when I go to wake it up


Turn off the hibernation feature. The only way to fix this issue is to upgrade the firmware on the motherboard. Simple to do but you run the risk of ruining the motherboard is you do it wrong.

Presario cq62 white screen


It sounds like there is a loose connection to the screen from the motherboard. As the motherboard gets warm it expands, which could be enough to break the circuit to the screen and cause the issues you are having. If so, the case will need to be opened and the connection checked and tightened. It may also be an inverter issue, this converts DC power to AC power and may be failing, not supplying enough power to run the screen.

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.

The display turn white >>>what can i do?


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.

Hp vs17 has white screen at boot. I have eliminated the chord from the tower and the tower works fine. I have audio, no video. Only a white blank screen. It does not blink or flicker. It just stays white....


There are three choices here...bad screen, bad connection, or bad video card, if the card is integrated onto the motherboard, then that part of the motherboard could be bad. If you have access to another monitor or a TV with a vga input, try the computer with another monitor. If you get a signal on that other monitor then you know you either had a bad connection with the other monitor or you lost the screen on the old one. Go back and reseat your video connections with the computer off. Don't ever remove or move cables to the monitor and video with the computer running...the screen can suffer permanent damage. If there is no signal on any monitor, then either you have a bad vga cord or your video graphics card had died.
