Troubleshooting
If you experience any of the following
difficulties while using the receiver, use this
troubleshooting guide to help you remedy the
problem. Also, see “Checking the connections”
on page 25 to verify that the connections are
correct. Should any problem persist, consult
your nearest Sony dealer.
There is no sound or only a very low-level sound
no matter which component is selected.
• Check that the speakers and components are
connected securely and correctly.
• Check that both the receiver and all the
components are turned on.
• Check that the MASTER VOLUME control is
not set at VOLUME MIN.
• Check that the SPEAKERS A/B button is not set
to “SPEAKER OFF” and is set accordingly to
your SPEAKERS FRONT system (page 27).
• Press MUTING to cancel the muting function.
• Check that the headphones are not connected.
• The protective device on the receiver has been
activated because of a short circuit (“PROTECT”
flashes). 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.
• Check that you have selected the correct
component on the receiver.
Precautions
On safety
Should any solid object or liquid fall into the cabinet,
unplug the receiver and have it checked by qualified
personnel before operating it any further.
On power sources
• Before operating the unit, check that the operating
voltage is identical with your local power supply.
The operating voltage is indicated on the nameplate
at the rear of the receiver.
• The unit is not disconnected from the AC power
source (mains) as long as it is connected to the wall
outlet, even if the receiver itself has been turned off.
• If you are not going to use the receiver for a long
time, be sure to disconnect the receiver from the
wall outlet. To disconnect the AC power cord,
grasp the plug itself; never pull the cord.
• (Models of area code U, CA only)
One blade of the plug is wider than the other for the
purpose of safety and will fit into the wall outlet
only one way. If you are unable to insert the plug
fully into the outlet, contact your dealer.
• AC power cord must be changed only at the
qualified service shop.
On heat buildup
Although the unit heats up during operation, this is
not a malfunction. If you continuously use this unit at
a large volume, the cabinet temperature of the top,
side and bottom rises considerably. To avoid burning
yourself, do not touch the cabinet.
On placement
• Place the receiver in a location with adequate
ventilation to prevent heat buildup and prolong the
life of the receiver.
• Do not place the receiver near heat sources, or in a
place subject to direct sunlight, excessive dust or
mechanical shock.
• Do not place anything on top of the cabinet that
might block the ventilation holes and cause
malfunctions.
On operation
Before connecting other components, be sure to turn
off and unplug the receiver.
On cleaning
Clean the cabinet, panel and controls with a soft cloth
slightly moistened with a mild detergent solution. Do
not use any type of abrasive pad, scouring powder or
solvent such as alcohol or benzine.
If you have any question or problem concerning your
receiver, please consult your nearest Sony dealer.
