If the whole image or part of the image remains still, the screen will gradually become darker to
reduce image retention. This is a feature to protect the panel, and is not a malfunction.

The message [Panel refresh did not finish] is
displayed. (only models equipped with an OLED
panel)
Panel refresh automatically runs after the TV has been used for a long period of time to reduce image
retention. If the TV is turned on, the AC power cord (mains lead) is unplugged, or the ambient
temperature falls outside of the range between 10°C (50°F) and 40°C (104°F) during the panel refresh,
the process will not complete and this message will appear.
If panel refresh started automatically, it will restart when you turn off the TV with the remote control.
If panel refresh was initiated manually, you must select it again.

You are concerned about an image retention. (only
models equipped with an OLED panel)
If the same image is displayed repeatedly or for long periods of time, image retention may occur.
You can manually perform a panel refresh to reduce image retention.
Note
Perform panel refresh 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 and bright colors easily cause image retention. Avoid displaying these
types of images for long periods of time, otherwise image retention may occur.
