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.
POWER
The power is not turned on.
• Check that the AC power cord (mains lead)
is connected securely.
The system is not turned on when the TV is
turned on.
• Check the TV speaker settings. The TV
speaker settings control how the system is
automatically turned on with the TV. To
enjoy the TV sound via the system, you need
to set the speaker settings of the TV to output
the sound from external audio equipment.
For details, refer to the operating
instructions of the TV.
• The system is not turned on when you turn
the TV on if sound was being output from
the TV speakers the last time the TV was
turned off.
The System Power Off function does not work.
• Change the setting of the TV to turn
connected components off automatically
when you turn off the TV. For details, refer
to the operating instructions of the TV.
The system is turned off when you turn off the
TV.
• When the Control for HDMI function is on,
the System Power Off function is active, and
the system is turned off when you turn off
the TV.
The system is turned off automatically.
• The AUTO STBY function is working
(page 51).
SOUND
Dolby Digital or DTS multi-channel sound is
not reproduced.
• Check that the Blu-ray Disc, DVD, etc., is
recorded in Dolby Digital or DTS format.
• When connecting the Blu-ray Disc, DVD
player, etc., to the digital input jacks of this
system, check the audio setting (settings for
the audio output) of the connected
component.
The surround effect cannot be obtained.
• Depending on the digital signal, the
surround processing may not work (page
37). Press DISPLAY to show the sound
format in the front panel display. If “2.0CH”
or “1.0CH” is displayed in the front panel
display, the signal is stereo or monaural and
does not include multi-channel sound. If
“5.1CH,” etc., is displayed, the signal
contains multiple channels, but the surround
effect may be subtle depending on the
program or disc.
No TV sound is output from the system.
• Check the connection of the digital optical
cord or audio cord that is connected to the
system and the TV (page 23).
• Check the sound output of the TV.
• If the TV is compatible with the ARC
function, set “CTRL HDMI” and “ARC” to
“ON.”
The sound is output from both the system and
the TV.
• If the Control for HDMI function is set to
off, or the selected component is not
compatible with the Control for HDMI
function, turn off the sound of the system or
the TV.
Sound lags behind the TV image.
• Set “A/V SYNC” to “OFF” if “A/V SYNC”
is set to “ON.”
The volume turns down when the output
method changes from the TV speaker to the
system speakers.
