Troubleshooting
If you experience any of the following difficulties while using the
system, use this troubleshooting guide to help remedy the problem
before requesting repairs. Should any problem persist, consult your
nearest Sony dealer.
Be sure to bring both your Bar Speaker and subwoofer, even if it
seems as though only one has a problem, when you request to
repair.
POWER
The system does not power up.
 Check that the AC power cord (mains lead) is connected securely.
The system is turned off automatically.
 The “A. STBY” function is working. Set “A. STBY (Auto standby)” to
“OFF” (page 13).
SOUND
No TV sound is output from the system.
 Repeatedly press the INPUT button on the remote control to
display “TV” in the display (refer to “Listening to the audio of the
TV” in the supplied Startup Guide).
 Check the connection of the HDMI cable, optical digital cable, or
audio cable that is connected to the system and the TV (refer to
“Connection” in the supplied Startup Guide).
 Check the sound output of the TV. Refer to the operating
instructions of the TV for the TV settings.
 Increase the volume on the TV or cancel muting.
 When a TV compatible with the Audio Return Channel (ARC)
technology is connected with an HDMI cable, make sure the cable
is connected to the HDMI input (ARC) terminal of the TV (refer to
“Connection” in the supplied Startup Guide).
 If the TV is not compatible with the Audio Return Channel (ARC)
technology, connect the optical digital cable in addition to the
HDMI cable in order to output sound (refer to “Connection” in the
supplied Startup Guide).
The sound is output from both the system and the TV.
 Turn off the sound of the system or the TV.
The TV sound from this system lags behind the image.
 Set “SYNC (AV sync)” to “OFF” if it is set to “ON” (page 12).
No sound or only a very low-level sound of the equipment
connected to the Bar Speaker is heard from the Bar Speaker.
 Press the VOL + button on the remote control and check the
volume level (refer to “Parts and controls” (page 21)).
 Press the MUTING or VOL + button on the remote control to cancel
the muting function (refer to “Parts and controls” (page 25)).
 Make sure the input source is selected correctly. You should try
other input sources by pressing the INPUT button on the remote
control several times (refer to “Listening to the sound” in the
supplied Startup Guide).
 Check that all the cables and cords of the system and the
connected equipment are firmly inserted.
No sound or only a very low-level sound is heard from the
subwoofer.
 Press the SW VOL + button on the remote control to increase the
subwoofer volume (refer to “Parts and controls” (page 25)).
 Make sure that the on/standby lamp on the subwoofer is lit in
green. If not, refer to “No sound is heard from the subwoofer.” in
“WIRELESS SOUND” (page 19).
 A subwoofer is for reproducing bass sound. In the case of input
sources that contain very little bass sound components (i.e., a TV
broadcast), the sound from the subwoofer may be difficult to
hear.
 When you play content compatible with copyright protection
technology (HDCP), it is not output from the subwoofer.
The surround effect cannot be obtained.
 Depending on the input signal and the sound field setting,
surround sound processing may not work effectively. The
surround effect may be subtle, depending on the program or disc.
 To play multi channel audio, check the digital audio output setting
on the device connected to the system. For details, refer to the
operating instructions supplied with the connected equipment.
