Windows 10: Unidentified Black Ball of Pixels that move upon applying pressure to it on the screen

So, I have this old laptop that runs Windows 8.1 which I'm not updating because I had loads of memories with this OS and it has 2 problems:- Laptop can't detect the battery that is inserted- Screen has 4 lines of pixels that won't go away with a pixel fixer, with a black ball of pixels that move when applying pressure to screenNow, mainly, this question is about the random black ball of pixels, not the battery problem, but if you find a solution to them both, that would be great. This "ball of pixels" isn't really some cluster of stuck or dead pixels, but what makes it hard to identify it is

gray/dead pixel can be fixed ?

A dead pixel is a defective pixel that remains unlit on an LCD screen. Dead pixels are always black and are most noticeable on a white background. A dead pixel occurs when the transistor that activates the amount of light that shows through all three sub-pixels malfunctions and results in a permanently black pixel. Dead pixels appear black while stuck pixels can be one constant color like red, blue or green. Dead pixels can not usually be fixed.





However, intermittent dead pixel can be fixed it using the pressure method-there is no harm trying.

If you come across LCD Monitors that has a stuck pixel (a point on the screen that is always lit), it is usually due to a transistor malfunction or uneven distribution of liquid in the liquid crystal display (TFT LCD). This can often be fixed.





A stuck pixel is a common pixel defect on LCD screens. Stuck pixels are most easily noticed on dark or black screens where it will appear red, green, blue, or any combination of the three colors including yellow, purple or even white.

The dead pixel are the once, whose one of the three sub-pixels are permanently off, producing a black pixel.

How to Fix Stuck Pixel?

The Pressure Method can be use to try repair stuck pixel.

1. Turn “On” the LCD Monitor and display a black image so that you can clearly locate where the stuck pixel is.

2. Use a damp washcloth and fold the washcloth around your finger so that when pressure is applied, you won’t scratch the screen.

3. Gently apply little pressure (massaging) on only the stuck pixel area otherwise you may create more stuck pixels. While still applying pressure you can turn the screen off and back “On” again for several times

4. Continue to apply the pressure on the stuck pixel until it totally gone (sometimes the stuck pixel may appeared again so you have to do it few more rounds).

5. If the stuck pixel is still there even after you have used the pressure method then I guess you have to use the software method.



Stuck pixels can often be re-energized by rapidly turning them on and off. There are screensavers available for download that will do this to your LCD screen.

JScreenFix – A website that randomly turns on and off each pixel at up to 60 times a second to fix stuck pixels.

DPT 2.20 – A Windows application to help locate and identify dead/stuck pixels. It also has a pixel exerciser built in to possibly get lazy pixels working again.

UDPixel 2.1 – A free Windows application which help you to locate and fix 1 or more stuck pixels.

If the stuck pixels still won’t go away even after you have run the software for many hours, then it could no longer be repaired and the only way is to replace the LCD panel or just send the LCD Monitor back to your customers telling them about the problem.

Normally customers will accept it as one or two stuck pixels won’t really affect them. If the LCD Monitor is under warranty then you have to inform your supplier about this but usually the supplier only will replace if there are more than 10 stuck or dead pixels in the LCD screen!

 

Dead Pixel?

Apply good pressure (don't overdo it) with a rounded pen directly on the pixel

turn off the monitor while holdind pressure.

Wait a couple of seconds and turn it back on.

When completely on, release pressure.

If if don't work, see more suggestions i guess.
