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 both the L
or R jack to an analog component and not
just to either the L or R jack. Use a
monaural-stereo cable (not supplied).
However, there will be no sound from the
center speaker when a sound field (PRO
LOGIC, etc.) is selected. When the center
speaker is set to "NO," sound is output
only from the front left/right speakers.
There is no sound from analog 2
channel sources.
• Check that the INPUT MODE is not set to
"COAX" nor "OPT" for the selected input
(page 90).
• Check that the MULTI IN is not selected.
• Check that the DIGITAL ASSIGN
function is not used to reassign the audio
input of another source to the selected
input (page 91).
There is no sound from digital sources
(from COAXIAL or OPTICAL input jack).
• Check that the INPUT MODE is not set to
"ANALOG" (page 90). Check that the
INPUT MODE is not set to "COAX" for
the sources from the OPTICAL input jack,
nor set to "OPT" for the sources from the
COAXIAL input jack.
• Check that the MULTI IN is not selected.
