There is no sound from one of the front
speakers.
• Connect a pair of headphones to the
PHONES jack to verify that sound is
output from the headphones. If only one
channel is output from the headphones, the
component may not be connected to the
receiver correctly. Check that all the cords
are fully inserted into the jacks on both the
receiver and the component. If both
channels are output from the headphones,
the front speaker may not be connected to
the receiver correctly. Check the
connection of the front speaker which is
not outputting any sound.
• Make sure you have connected to both the
L and R jacks of an analog component, and
not only to either the L or R jack. Use an
audio cord (not supplied).
There is no sound from analog 2
channel sources.
• Check that the INPUT MODE is not set to
"AUTO" (page 55) and the DIGITAL
connection is not made for the selected

"AUTO" (page 55) and the "A. ASSIGN"
function is not used to reassign the audio

(from COAXIAL or OPTICAL input jack).
• Check that the INPUT MODE is not set to

not used to reassign the audio input of
another source to the selected input (page
