The parental lock password has been
forgotten.
• Enter 4357 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
colors (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 AC
power cord is unplugged during the Panel
refresh, the Panel refresh is not completed.
