Troubleshooting
If you experience any of the following
difficulties while using the receiver, use this
troubleshooting guide to help you remedy the
problem.
Audio
There is no sound, no matter which
component is selected, or only a very
low-level sound is heard.
• Check that the speakers and components
are connected correctly and securely.
• Check that all speaker cords are connected
correctly.
• Check that both the receiver and all
components are turned on.
• Check that MASTER VOLUME is not set
to “VOL MIN”.
• Check that the SPEAKERS (OFF/A/B/
A+B) is not set to off (page 30).
• Check that headphones are not connected.
• Press MUTING on the remote to cancel
the muting function.
• Check that you have selected the correct
component with the input buttons (page
38).
• When only a very low-level sound is
heard, check to see if NIGHT MODE is
activated (page 61).
• The protective device on the receiver has
been activated. Turn off the receiver,
eliminate the short-circuit problem, and
turn on the power again.
There is no sound from a specific
component.
• Check that the component is connected
correctly to the audio input jacks for that
component.
• Check that the cord(s) used for the
connection is (are) fully inserted into the
jacks on both the receiver and the
component.
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 75) and the DIGITAL and
HDMI connection is not made for the
selected input.
• Check that the DIGITAL ASSIGN
function is not used to reassign the audio
input of another source to the selected
input (page 76).
There is no sound from digital sources
(from COAXIAL or OPTICAL input jack).
• Check that the INPUT MODE is not set to
“ANALOG” (page 75).
• Check that the ANALOG DIRECT
function 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 76).
