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. Note that if service 
personnel changes some parts during repair, 
these parts may be retained.

• “AUTO.STBY” is set to “STBY ON” 

• The Sleep Timer function is working 

• Check that the DVD, etc. you are playing 

is recorded in Dolby Digital or DTS 
format.

• When connecting the DVD player, etc., to 

the digital input jacks of this receiver, 
make sure the digital audio output setting 
of the connected equipment is available.

• Set “AUDIO.OUT” to “AMP” in the 

HDMI menu.

• Make sure you have selected the sound 

field for movie or music mode (page 43).

• Sound fields do not function when DTS-

HD Master Audio, DTS-HD High 
Resolution Audio or Dolby TrueHD with 
sampling frequency of more than 48 kHz 
are being received.

• 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 
equipment 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 equipment. 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 connected to both the 

L and R jacks of an analog equipment, 
analog equipment requires both L and R 
jack connections. Use an audio cord (not 
supplied).

• Check that the speaker settings are 

appropriate for the setup using the AUTO 
CAL menu* or “PATTERN” in the 
SPEAKER menu. Then check that sound 
is output from each speaker correctly, 
using “T. TONE” in the LEVEL menu 
(page 35).

• Adjust the speaker level (page 54).
• Check that the subwoofer is connected 

correctly and securely.

• Make sure you have turned on your 

subwoofer.

• Depending on the selected sound field, no 

sound will be available from the 
subwoofer.

• When all speakers are set to “LARGE” 

and “NEO6 CIN” or “NEO6 MUS” is 
selected, there is no sound from the 
subwoofer.

• Some discs have no Dolby Digital 

Surround EX flag even though the 
packages have Dolby Digital Surround EX 
logos.
