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.
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.
This is a characteristic of liquid crystal panels and is not a problem.
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.
