Specifications - Sony BRAVIA KD-77A1 Reference Manual

You are concerned about image retention.

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, logos and bright colours
(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.
The message [Panel refresh did not finish...] is
displayed.
Panel refresh automatically runs after the TV has
been used for long periods of time to reduce
image retention. If the TV is turned on, the
mains lead is unplugged, or the room
temperature falls outside of the range between
10 ºC and 40 ºC during the Panel 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.

If Panel refresh initiated manually, you must
select it again.
