Troubleshooting

If you experience any of the following
difficulties while using the receiver, use this
troubleshooting guide to help you remedy the
problem. Should any problem persist, consult
your nearest Sony dealer.
There is no sound no matter which component
is selected.
• Check that both the receiver and all components
are turned on.
• Check that the MASTER VOLUME control is not
–
set at dB.
• Check that the SPEAKERS is not set to "OFF"
(page 50).
• Check that all speaker cords are connected
correctly.
• Press MUTING on the remote to cancel the
muting function.
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 not connected only the L or R
jack to a monaural component. Use a monaural-
stereo cable (not supplied) and connect it to both
the L and R jacks. 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
front L/R speakers.
There is no sound or only a very low-level
sound is heard.

component with INPUT SELECTOR.

(page 50).
• Check that the headphones are not connected.
• Press MUTING on the remote to cancel the
muting function.

to see if NIGHT MODE is activated (page 36).

activated. Turn off the receiver, eliminate the
short-circuit problem and turn on the power again.
There is no sound from analog 2 channel
sources.
• Check that the DIGITAL ASSIGN function is not
