Troubleshooting—Continued
The surround back speakers produce no sound
• Depending on the current listening mode, no sound
may be produced by the surround back speakers.
Select another listening mode (page 67).
• Not much sound may be produced by the surround
back speakers with some sources.
• Make sure the speakers are configured correctly
(page 70).
• While Powered Zone 2 is being used, playback in the
main room is reduced to 5.1-channels and the sur-
round back speakers produce no sound (page 85).
The subwoofer produces no sound
• When you play source material that contains no infor-
mation in the LFE channel, the subwoofer produces
no sound.
• Make sure the speakers are configured correctly
(page 70).
There’s no sound with a certain signal format
• Check the digital audio output setting on the con-
nected device. On some game consoles, such as those
that support DVD, the default setting is off.
• With some DVD-Video discs, you need to select an
audio output format from a menu.
• Depending on the input signal, some listening modes
cannot be selected (pages 63-66).
Can’t select the Pure Audio listening mode
• The Pure Audio listening mode cannot be selected
while Zone 2 is on. (Pure Audio listening mode is not
available for North American/Taiwan models.)
Can’t get 6.1/7.1 playback
• If no surround back speakers are connected, or the
Zone 2 speakers are being used, 6.1/7.1 playback is
not possible.
• You can not always select all of the listening modes,
depending on the number of the speakers connected
(pages 63-66).
The volume cannot be set to 79
• Check to see if a maximum volume has been set
(page 80).
• If the volume level of each individual speaker has been
adjusted to high positive values (page 72), then the
maximum master volume possible may be reduced.
Note that the individual speaker volume levels are set
automatically after the Audyssey 2EQ™ Room Cor-
rection and Speaker Setup function has been com-
pleted (
page 47
).
Noise can be heard
• Using cable ties to bundle audio cables with power
cords, speaker cables, and so on may degrade the
audio performance, so don’t do it.
• An audio cable may be picking up interference. Try
repositioning your cables.
The Late Night function doesn’t work
• Make sure the source material is Dolby Digital, Dolby
Digital Plus, and Dolby TrueHD (page 75).
About DTS signals
• When DTS program material ends and the DTS bit-
stream stops, the AV receiver remains in DTS listen-
ing mode and the DTS indicator remains on. This is to
prevent noise when you use the pause, fast forward, or
fast reverse function on your player. If you switch your
player from DTS to PCM, because the AV receiver
does not switch formats immediately, you may not
hear any sound, in which case you should stop your
player for about three seconds, and then resume play-
back.
• With some CD and LD players, you won’t be able to
playback DTS material properly even though your
player is connected to a digital input on the AV
receiver. This is usually because the DTS bitstream
has been processed (e.g., output level, sampling rate,
or frequency response changed) and the AV receiver
doesn’t recognize it as a genuine DTS signal. In such
cases, you may hear noise.
• When playing DTS program material, using the pause,
fast forward, or fast reverse function on your player
may produce a short audible noise. This is not a mal-
function.
The beginning of audio received by an HDMI IN
can’t be heard
• Since it takes longer to identify the format of an
HDMI signal than it does for other digital audio sig-
nals, audio output may not start immediately.
There’s no picture
• Make sure that all video connecting plugs are pushed
in all the way (page 22).
• Make sure that each video component is properly con-
nected. (pages 24-36)
• If your TV is connected to the HDMI OUT, select
“- - - - -” in the “HDMI Input Setup” on page 40 to
watch composite video, and component video sources.
• If the video source is connected to a component video
input, you must assign that input to an input selector
(page 41), and your TV must be connected to either
the HDMI OUT or COMPONENT VIDEO MONI-
TOR OUT (pages 27 and 24).
• If the video source is connected to a composite video
input, your TV must be connected to the HDMI OUT
or the corresponding composite video output
(pages 27 and 24).
• If the video source is connected to an HDMI input,
you must assign that input to an input selector
(page 40), and your TV must be connected to the
HDMI OUT (page 24).
• While the Pure Audio listening mode is selected, the
video circuitry is turned off and only video signals
input through HDMI IN can be output.
• On your TV, make sure that the video input to which
the AV receiver is connected is selected.
