Troubleshooting—Continued
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 
The Zone 2 speakers produce no sound 
• The Zone 2 speakers only output sources that are con-
nected to an analog input. Check to see if the source is 
connected to an analog input.
There’s no sound with a certain signal format
• Check the digital audio output setting on the con-
nected device. On some games consoles, such as those 
that can play DVDs, the default setting is off.
• With some DVD-Video discs, you need to select an 
audio output format from a menu.
Can’t get 6.1- or 7.1-channel playback
• When the ZONE 2 SPEAKERS terminals are used, 
playback in the main room is reduced to 5.1-channels.
The volume cannot be set to +18 dB (99)
• After the Automatic Speaker Setup function has been 
used, or the volume level of each speaker has been 
adjusted (pages 58, 73), the maximum possible vol-
ume setting be reduced.
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 
The multichannel DVD input doesn’t work
• Check the multichannel DVD input connections 
• To select the multichannel DVD input, press the 
[MULTI CH] input selector button.
• Check the audio output settings on your DVD player.
About DTS signals
• 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.
• 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 3 seconds, and then resume playback.
• With some CD players, you won’t be able to playback 
DTS material properly even though your player is con-
nected 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 recog-
nize it as a genuine DTS signal. In such cases, you 
may hear noise.
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 24).
• Make sure that each video component is properly con-
nected.
• If a video component is connected to a component 
video input, your TV must be connected to the COM-
PONENT VIDEO OUT or HDMI OUT (page 25).
• If a video component is connected to an HDMI input, 
your TV must be connected to the HDMI OUT.
• While the Pure Audio listening mode is selected, the 
video circuitry is turned off and only the HDMI OUT 
outputs video signals.
• On your TV, make sure that the video input to which 
the AV receiver is connected is selected.
• To watch a composite video or S-Video source on a 
TV that’s connected to the COMPONENT VIDEO 
OUT, select “- - -” in the “Component Video Setup” on 
page 44.
• To watch a composite video, S-Video, or component 
video source on a TV that’s connected to the HDMI 
OUT, select “- - -” in the “HDMI Video Setup” on 
page 43.
There’s no picture from a source connected to 
an HDMI IN
• If the message “Resolution Error” appears on the AV 
receiver’s display, this indicates that the TV or display 
does not support the current video resolution and you 
need to select another resolution on your DVD player.
The onscreen menus don’t appear
• On your TV, make sure that the video input to which 
the AV receiver is connected is selected.
The picture is distorted
• On non-North American models, specify the TV sys-
tem used in your area in the “TV Format Setup” on 
page 47.
The immediate display does not appear
• The immediate display (operation details) may not 
appear on a TV that’s connected to the HDMI OUT or 
COMPONENT VIDEO OUT.
