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
(page 46).
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 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 (page 59).
Can’t select the DTS-ES Discrete/Matrix or THX
Surround EX (DTR-6.5 only) listening modes?
• These modes cannot be selected when no surround
back speakers are connected, or the Zone 2 speakers
are being used.
Can’t get 6.1 playback?
• If no surround back speakers are connected, or the
Zone 2 speakers are being used, 6.1 playback is not
possible.
The volume cannot be set to 99?
• When the levels of all speakers have been calibrated
(page 50), the maximum volume setting may change.
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
(page 62).
The DVD analog multichannel input doesn’t
work?
• Check the DVD analog multichannel input connec-
tions (page 29).
• To select the DVD analog multichannel input, press
the [Multi CH] input selector button.
• Check the audio output settings on your DVD player.
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.
There’s no picture?
• Make sure that all video connecting plugs are pushed
in all the way (page 21).
• Make sure that each video component is properly con-
nected.
• If your video component is connected to a component
video input, your TV must be connected to the compo-
nent video output (page 26).
• On your TV, make sure that the video input to which
the AV receiver is connected is selected.
• While the Pure Audio listening mode is selected, the
video circuits are turned off and the AV receiver out-
puts no video signals.
The onscreen menus don’t appear?
• Make sure that the video settings are correct
(page 43).
• On your TV, make sure that the video input to which
the AV receiver is connected is selected.
• Depending on the display device, when the “b. Scan
Mode” setting on the “6-3. OSD Setup” menu is set to
Non-Interlaced, the onscreen setup menus may not
appear. If this happens, use the AV receiver’s display
and change that setting to Interlaced.
