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 "Set-up" menu (page 32).
• See "Picture noise" causes/remedies on page 53.
Cause/Remedy
• Switch between digital and analogue mode and select the desired digital/
analogue channel.
• Scrambled/Subscription only channel. Subscribe to the Pay Per View
service.
• Channel is used only for data (no picture or sound).
• Contact the broadcaster for transmission details.
• Contact a local installer to find out if digital transmissions are provided in
your area.
• Upgrade to a higher gain aerial.
Cause/Remedy
• Check if the "Sleep Timer" is activated, or confirm the "Duration" setting of
"On Timer" (page 31).
• 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.)
• If no signal is received and no operation is performed in the TV mode for
10 minutes, the TV automatically switches to standby mode.
• Check if the "On Timer" is activated (page 31).
• Select "AV Preset" in the "AV Set-up" menu and cancel "Skip" of the input
source (page 34).
