LC-40LB480U Full HD LED 1080p TV
The Audio
Return
Channel
setting on the
CEC menu
keeps turning
back on after it
is turned off.
• When Audio Return Channel is
set to Off and CEC Control is set
to On and you adjust the volume
on the audio receiver, Audio
Return Channel is automatically
set to On. To prevent this from
happening, turn off the CEC
Control feature. See “Turning CEC
Control on or off” on page 35.
Problem Solution
I cannot select
the Root Menu
option on the
CEC menu.
OR
The device’s
root menu does
not open when
I select Root
Menu on the
CEC menu.
• The device may not support this
feature. See the documentation
that came with the device for
more information.
Note
If the problem is not solved by using these
troubleshooting instructions, turn off your
TV, then turn it on again.
