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 liquid crystal 
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 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.
Image retention appears
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.
