Sony BRAVIA XR XR-77A8 K Series Reference Manual page 6

The remote control does not function.
• Replace the batteries.
The parental lock password has been
forgotten.
• Enter 9999 for the PIN and enter the new PIN.
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
• Perform Panel refresh only when image retention is
particularly noticeable. Avoid performing Panel
refresh 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.
The message [Panel refresh did not finish...] is
displayed.
When i) the TV is turned on or ii) the mains lead
is unplugged during the Panel refresh, the Panel
refresh is not completed. Please avoid the
above two conditions during the Panel refresh.
For more information on
troubleshooting, refer to the Help
Guide.
