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.
