This is a characteristic of liquid crystal panels. This is not a
malfunction and can not be a reason for service claim.
The liquid crystal panel is built with very high precision
technology giving you fine picture details. Occasionally, a
few non-active pixels may appear on the screen as a fixed
point of blue, green, or red.
