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 61).
 
Can’t select the DTS-ES Discrete/Matrix or THX 
Surround EX (TX-SR702/702E 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 64).
 
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).
• Models other than the TX-SR702/702E, TX-SR602E, 
and Australian TX-SR602 do not support video upcon-
version, so composite video and S-Video sources are 
not output by the COMPONENT VIDEO OUT.
• On your TV, make sure that the video input to which 
the AV receiver is connected is selected.
• While the Pure Audio listening mode (not all models) 
is selected, the video circuits are turned off and the AV 
receiver outputs 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.
