The message [Panel refresh did not finish] is
displayed. (only models equipped with an OLED

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. Start the
procedure again from the beginning.

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. This issue is not a malfunction.
The TV has two functions, [Pixel shift] and [Panel refresh], that are designed to reduce
image retention.
You can perform a [Panel refresh] when necessary.
Press the (Quick Settings) button on the remote control, then select
[Settings] — [Display & Sound] — [Expert panel settings] — [Panel refresh].
Hint
[Pixel shift] is a feature that helps prevents image retention by automatically moving
the image at fixed intervals. Under normal circumstances, keep this option enabled.
