How to Remove a Stuck pixel
Sometimes LCD screens have a stuck(Always shows one color).This is because of transistor problem or unequal distribution of liquid in liquid crystals.
Dead pixel
Stuck pixels are often incorrectly referred to as "dead pixels", which have a similar appearance. In a dead pixel, all three sub-pixels are permanently off, producing a pixel which is permanently black.
Stuck pixel
A stuck pixel is a dot on LCD screen that permanently shows one color no matter what picture your are viewing.Most common are Red, Green, or Blue colors but can also have a combination of these.Stuck pixel is a common problem occurring in LCDs.
Actually a pixel in LCD screen is further composed of three sub-pixels Red, Green, Blue a stuck pixels is produced because of manufacturing fault when one or two of these sub-pixels are faulty and permanently shows only the third color or a combination of the other two.
To locate a stuck pixel a dark color background should be used because its not easily visible in light background.
