Dead pixels are an unfortunate side effect that we have to live in our modern universe focused on visualization, but they don't have to be a constant problem. And while you can pay someone to fix it (or completely replace the screen) there are some useful methods to erase dead pixels and return the screen to the way it was before. Next, we show you how to repair dead pixels.
Dead? Or just stuck?
The first step in this pixel repair journey is to learn the difference between a dead pixel and a stuck pixel. Each individual pxel on an LCD screen is composed of three subpixels (red, green and blue) that appear white when they are turned on and black when they are turned off. Together, these three subpixels generate all the colors of the spectrum.
We are facing a stuck pixel when one or two of the subpixels remain on while the rest is off. Its appearance will vary in appearance depending on which subpixels work correctly. On the other hand, a dead pxel appears when an entire pxel or a set of subpixels remain off. The stuck pixels are generally easier to repair than dead pixels.
Neither of them should be confused with the so-called hot pixels, which are a temporary problem limited to the photograph or videography.
If the screen pixels are stuck, there may be a way to save them. That said, although we can guarantee the validity of the methods we will list below, we cannot guarantee it in all cases, so your first action should be to verify if your screen is still within the warranty period. It is probably preferable to replace it with a completely new (and free) one, but if the warranty has already passed, or you simply want to know how to repair a dead pixelel by yourself, read on
JScreenFix is the ideal pixel fix solution for everyone. It is a web application, so no downloads are needed. This also makes it suitable for a wide variety of platforms, including iOS and MacOS.
Step 1: Open your favorite browser and go to the JScreenFix homepage.

Step 3: Drag the white noise window to where your stuck or dead pxel is, and then let it run for half an hour.
JScreenFix states that most pixels can be repaired in less than 10 minutes, but giving you enough time to work is never over. Try using it a couple more times, if the first execution is not successful.
In any case, if it doesn't work, you can always try some other tools.
PixelHealer is a totally free application of Aurelitec, designed to solve pixel problems. If your screen with dead pixels is connected to a Windows PC, this should be the solution. It is compatible with many versions of Windows, from Windows 7 to Windows 10.
Once downloaded, PixelHealer will present a colored box and a configuration menu. Click and drag or use the position and size options to place the color box over the area of the dead pixels. Being careful not to look directly at the box (especially if you are sensitive to blinking images), click on the “Start flashing".
The window begin to flash in several colors very quickly. Djalo act for 30 minutes (s: thirty minutes) and then check the pxel again. Try this a few times to see if it works. This is the most common method there is when trying to resuscitate a pxel. Basically, what you are doing is trying to bring the pixel back to life, forcing an appropriate response that will make it act as before.
It should be said that it is more likely to work in a stuck pxel that still shows signs of life than in a dead pxel, which may remain insensitive to this treatment. But there is a possibility that both can be fixed, so try this method, regardless of how the pxel behaves.
If you are not sure where the problem is really with the pixels on your screen, you can use the InjuredPixels application.

Dead Pixel Detect And Fix (Android)
Dead Pixel Detect And Fix (DPDF) is a simple method to locate and repair potentially dead or stuck pixels. The free application is available for Android 2.3 and later, and has an interface that explains itself and is easy to navigate.

To download DPDF, go to the Google Play Store, or touch the “Play Store” cone on your Android device to access it. Search for “Dead Pixel Detect And Fix” and describe it as you will with any other application. Once installed, brelo touching the DPDF cone.
Touch the screen to open the main application menu, and then choose the “Colors” button in the upper left corner. Go through the six presets individually: red, green, blue, white, black and gray. You can also choose the “Customize” option at the top and choose a color from the resulting palette (without using all colors).
Doing either of these two options lets you know where a dead or stuck pixel is on your screen.
When you know it, return to the small welcome screen and touch the screen once more to bring up the main application menu. Choose "Repair" to begin the default 30-minute color cycle process. If you want to change the duration, use the "Settings" menu. Of course, let this repair function run for at least 20 minutes before closing it.
When the cycle is complete, return to the welcome screen, access the menu as before and choose the “Colors” option again. Cycle through the same colors you used to locate the dead or previously stuck pixel, and check if everything has returned to normal.
