Troubleshooting
If you experience any of the following difficulties while
using the amplifier, use this troubleshooting guide to help
you to remedy the problem. Should any problem persist,
consult your nearest Sony dealer.
There is no sound, or only a very low-level sound
is heard.
, Check that the amplifier is turned on.
, Check that the speakers are connected correctly
and securely.
, Press MUTING to check the muting status.
, Check to see if the protection circuit on the
amplifier has been activated because of a short
circuit (the IN USE indicator flashes red). Turn off
the amplifier, eliminate the short-circuit problem
and turn the power on again.
, Adjust the ATTENUATOR on the amplifier and
the volume on the learned remote.
, If all steps above cannot remedy the problem, clear
the amplifier’s memory (page 15).

reversed.
, Check that the speakers and components are
connected correctly and securely.

transformer or motor, and at least 10 feet (3
meters) away from a TV set or fluorescent light.
, Move your TV away from the audio components.
, The plugs and jacks are dirty. Wipe them with a
cloth slightly moistened with alcohol.
The IR Remote Control does not function.
, Point the Remote Control at the remote sensor
on the IR receiver.
, Remove any obstacles in the path between the
Remote Control and the IR receiver.
, Replace both batteries in the Remote Control with
new ones, if they are weak.
, Check that you have selected the correct function
on the Remote Control.
, Make sure the IR code setting is correct.
, Make sure the IR ID TEST switch is set to “OFF”.
The POWER switch is on but the IN USE indicator
does not light up when AUTO POWER SELECTOR is
