green, red, and blue dots remain on
the display) or there are dots not dis-
playing the correct colors z If an image is displayed for a prolonged period of time, an afterimage may
appear. This is not a malfunction. The afterimage will disappear when a dif-
ferent screen is displayed.
z High-precision and advanced technologies are used in the production of
color liquid crystal displays (color LCDs). Therefore, if 0.002% or less of the
picture’s elements either fail to light or remain constantly lit (that means that
more than 99.998% of the elements are functioning properly), this is not
considered a defect.
