Uneven color uniformity
appears on the screen when
the TV is powered on
Cause/Remedy
• This is probably caused by the authentication process between HDMI
equipment and the TV. It does not indicate a malfunction.
• This is due to strong light reflecting off both the TV screen and reflections
coming from behind the screens.
• Position your TV away from strong ambient light or sunlight, or lower any
ambient lights.
Cause/Remedy
• Press 2 +/– or % (Mute).
• Check that "Speaker" is set to "On" in the "Setup" menu (page 29).
• See "Picture noise" causes/remedies on page 44.
Cause/Remedy
• Scrambled/Subscription only channel. Subscribe to the Pay Per View
service.
• Contact the broadcaster for transmission details.
• Check that the "Program Block" is set to "Allow" in the "Channel Setup"
menu (page 31).
Cause/Remedy
• Check if the "Sleep Timer" is activated, or confirm the "Duration" setting of
"On Timer" (page 28).
• If the inside of the TV grows warm while Cooling Mode is set to "High",
the TV automatically switches to standby mode.
(When Cooling Mode is set to "Normal" under the same conditions, the
mode switches to "High", the cooling fan starts, and a loud whirring noise
may be heard.)
• Check if the "On Timer" is activated (page 28).
• Select "Video Labels" in the "AV Setup" menu and cancel "Skip" of the
input source (page 30).
• After turning on the TV, you may notice a slight variation in color (tint) and
brightness in certain areas of the picture. This will last only a few minutes
each time you turn on the TV. This is a normal temperature characteristic of
the components and not a malfunction.
