LCD Display panel
Symptoms
Check
The screen darkens slightly when bright pictures
with minimal movements are shown.
The screen will darken slightly when photos, still images of
a computer or other pictures with minimal movements are
shown for an extended period. This is done to reduce image
retention on the screen and the shortening of the screen’s
service life: It is normal and not indicative of malfunctioning.
It takes a while for the picture to appear.
The unit digitally processes the various signals in order
to reproduce esthetically pleasing images. As such, it
sometimes takes a few moments for the picture to appear
when the power has been turned on, when the input has
been switched.
The edges of the images flicker.
Due to the characteristics of the system used to drive the
panel, the edges may appear to flicker in the fast-moving
parts of the images: This is normal and not indicative of
malfunctioning.
There may be red spots, blue spots, green spots
and black spots on the screen.
This is a characteristic of liquid crystal panels and is
not a problem. 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 fixed points of red, blue, green, or black. Please
note this does not affect the performance of your LCD.
Image retention appears
Image retention may occur. If you display a still picture for
an extended period, the image might remain on the screen.
However, it will disappear when a general moving picture is
displayed for a while. This is not considered as malfunction.
This LCD Display uses special image processing. Hence a slight time lag may occur between image and audio,
depending on the type of input signal. However, this is not a malfunction.
