Troubleshooting
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 fl icker. Due to the characteristics of the system used to drive the panel, the edges may appear to fl icker 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 fi ne picture details. Occasionally, a few non-active
pixels may appear on the screen as fi xed 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 after a while. This is not considered as malfunction.
