The TV and its surroundings become
warm.

become warm to the touch. This is not a
malfunction of the TV.
The screen becomes darker while
watching TV.
If the whole image or part of the image

remains still, the screen brightness will be
gradually reduced to prevent image
retention. This is not a malfunction of the TV.
You are concerned about image
retention.
If the same image is displayed repeatedly
or for long periods of time, image retention
may occur. To reduce image retention, we
recommend that you turn off the TV
normally by pressing the power button on
the remote control or the TV.
Note Note
• Perform Panel refresh manually only when
image retention is particularly noticeable. As a
reference, perform it only once a year. Avoid
performing it more than once a year because it
may affect the usable life of the panel.
• Images that include clocks, logos and bright
colors (including white) easily cause image
retention. Avoid displaying these types of
images for long periods of time, otherwise
image retention may occur.
A white line appears on the screen.
Panel refresh automatically runs after the TV

has been used for long periods of time to
reduce image retention. Panel refresh starts
after the TV is turned off and takes about
one hour to complete. A white line may be
displayed on the screen during the Panel
refresh. This is not a malfunction of the TV.
