 LC-32LB370U/LC-50LB370U Sharp 32"/50" LED 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 38.
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.

If the problem is not solved by using these 
troubleshooting instructions, turn off your 
TV, then turn it on again.
