How to Fix Dead Pixels on a Laptop
Dead or defective pixels are pixels on the LCD monitor that do not display properly. This could be a dark or bright dot. A dead pixel is always dark against a bright background.
Switch off the laptop. Mark where the dead pixel is located.
Use the eraser end of the pencil or your finger to apply pressure on the dead pixel. Apply pressure lightly. You can also use a damp cloth to apply pressure to avoid scratch marks.
Switch on the laptop when applying pressure. Rub gently to move the liquid in the crystal.
Download a flashing program for dead pixels. Alternatively, you can play YouTube videos that are designed to fix dead pixels.
Run the program that flashes the basic colors for at least an hour.
Check whether the dead pixel has been fixed.
