How to Stop Dead Pixels From Spreading

By Ricardo Barboza

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.

Screen Massage

Step 1

Use a removable office sticky note to mark the location of the dead pixels, then turn off the LCD screen.

Step 2

Dampen a cloth. Apply pressure to the area with the dead pixel with one finger.

Step 3

While keeping pressure on the area, turn the LCD screen back on.

Step 4

Remove the pressure from the screen. The dead pixel will be eliminated and will be unable to spread.

Computer Pixel Repair Software

Step 1

Download the free JScreenFix software program, available from www.jscreenfix.com or from a free download site. Open the JScreenFix applet.

Step 2

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.

Step 3

Run the applet for 20 minutes. This will display fast-moving color patterns over the dead pixel area.

Step 4

Check your screen after the 20 minutes. The dead pixel should be removed.

Tips & Warnings

  • Do not press too hard when applying pressure to the LCD screen. This may cause more dead pixels.
