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

refresh, the process will not be completed and
this message will appear.

If Panel refresh started automatically, it will restart
when you turn off the TV with the remote control.
