If [Presence Sensor] is set to [Moderate], the screen darkens
temporarily when the sensor does not recognize any facial patterns,
or the picture turns off after no movement is detected for a preset
time. (For Intelligent Presence Sensor-compatible models only.)
The screen alternates between dark and bright.
If [Presence Sensor] is set to [Moderate], the screen darkens
temporarily when the sensor does not recognize any facial patterns,
or the picture turns off after no movement is detected for a preset
time. (For Intelligent Presence Sensor-compatible models only.)
Blurry picture or poor color.
Transporting the TV from a cold to a warm location or a sudden
change in room temperature may cause moisture condensation,
resulting in a blurry picture or poor color. Turn off your TV and wait a
few hours before powering on again.
Wide Mode changes automatically.
When changing the channel or video input, if [4:3 Default] in [Screen]
is not set to [Off], the current [Wide Mode] setting is automatically
replaced with the [4:3 Default] setting. To lock in [Wide Mode]
selected with WIDE on the remote control, set [4:3 Default] to [Off].
Check the [Auto Wide] setting in [Screen].
Suddenly the picture becomes small.
The picture becomes smaller during commercials due to the method
used by a provider to broadcast content. When HD content channels
switch to SD content (commercials), the picture may be small with a
black border.
[Auto Wide] will not expand the picture while the content switches,
since the content information is regulated by the channel signal
provider. You can manually change the [Wide Mode] setting if desired,
which will remain in effect until you change the channel/input or
manually change the [Wide Mode] setting again.
Black box on screen.
A text option is selected although no text is available. To deactivate
this feature, set [CC Display] to [Off]. If you are trying to select closed
captioning, select [CC1] instead of [Text1] - [Text4] (options may not
be available depending on your region/country).
Black bands appear at the edges of the screen.
Some wide screen programs are filmed in aspect ratios that are
greater than 16:9 (this is especially common with theatrical releases).
