Dead pixels often occur in the LCD screens of computers, televisions and other devices. This happens when a component fails and causes a pixel to go black. Sometimes this can spread to other pixels, which can appear as a "hole" in the screen. This is frustrating when watching television or using the computer. Following these steps can help to remove dead pixels and prevent them from spreading.

Use a removable office sticky note to mark the location of the dead pixels, then turn off the LCD screen.
Dampen a cloth. Apply pressure to the area with the dead pixel with one finger.
While keeping pressure on the area, turn the LCD screen back on.
Remove the pressure from the screen. The dead pixel will be eliminated and will be unable to spread.
Download the free JScreenFix software program, available from www.jscreenfix.com or from a free download site. Open the JScreenFix applet.
Move the applet to where the dead pixel is located on the screen. If there are multiple dead pixels, you can expand the size of the applet.
Run the applet for 20 minutes. This will display fast-moving colour patterns over the dead pixel area.
Check your screen after the 20 minutes. The dead pixel should be removed.
