Symptom Possible cause Remedy
Audio
The surround back speak-
ers produce no sound?
The level of the surround back speaker is set
at minimum.
Check the volume of the surround back
speaker (page 49).
The Surround Back setting is set to None in
the Speaker Configuration.
Check the Surround Back setting in the
Speaker Configuration (page 32).
The selected listening mode doesn’t use the
surround back speakers.
Select another listening mode. See page 42
for information on listening modes.
Surround speaker output depends on the
source material, and some material may not
use the surround speakers much.
If you’re playing a Dolby Digital EX or
DTS-ES source, make sure that the Dolby
Digital/DTS setting is set to On (page 44).
A low-frequency noise or
hum can be heard?
The audio connecting cables at the rear of
the AV Receiver are too close to the power
cord.
Untangle the audio cables and position them
as far away as possible from the power cord.
The sound is too bright or
harsh and the high range is
not clear?
The treble is set too high. Adjust the treble (page 38).
The subwoofer is not work-
ing or is very quiet?
The Subwoofer setting is set to No in the
Speaker Configuration.
Check the Subwoofer setting in the Speaker
Configuration (page 32).
The volume of the subwoofer is set at mini-
mum.
Check the volume of the subwoofer
(page 49, 35).
Speaker set A is turned off. The subwoofer
output does not work while only speaker set
B is on.
Turn on speaker set A.
Video
There’s no picture on the
TV?
The Pure Audio listening mode is selected.
When this mode is selected, the display and
the internal video circuits are all turned off
and no video signals are output.
The TV’s input selector is set incorrectly.
Select the correct input on the TV (i.e., the
input to which the AV Receiver is con-
nected).
The video input and output are different for-
mats.
The AV Receiver doesn’t convert between
video formats. It works as a video signal
switcher. Composite video input signals are
output only by composite video outputs.
S-Video input signals are output only by
S-Video outputs. And component video input
signals are output only by component video
outputs.
Remote controller
The buttons on the AV
Receiver work OK but those
on the remote controller
don’t?
The wrong remote controller mode is
selected.
Select the correct mode (page 10).
The batteries are installed incorrectly.
Check the batteries and correct as necessary
(page 9).
You’re not pointing the remote controller at
the AV Receiver’s remote sensor.
Point the remote controller at the AV
Receiver’s remote sensor (page 9).
Can’t use the remote con-
troller with other AV com-
ponents?
You’ve connected a MiniDisc recorder or
CD recorder to the AV Receiver but haven’t
changed the TAPE/MD/CDR display.
Press and hold the [TAPE] input selector
button until MD or CDR, as appropriate,
appears on the display.
The wrong remote control code has been
entered.
If more than one code is listed, try each one
(page 50).
With some AV components, certain buttons
may not work as expected and some may not
work at all.
You’re pointing the remote controller at the
wrong AV component.
To control a component connected via ,
point the remote controller at the AV
Receiver. To control a component that’s not
connected via , point the remote control-
ler at that component (page 50)
You’ve made an connection but not an
analog audio connection (RCA).
To use , you must make an connection
and an analog audio connection (RCA)
between the component and AV Receiver,
even if they are connected digitally
(page 30).
