Troubleshooting —Continued
Symptom
The surround back speak-
ers produce no sound?

hum can be heard?
The sound is too bright or
harsh and the high range is
not clear?
The subwoofer is not work-
ing or is very quiet?
There's no picture on the
TV?
The buttons on the AV
Receiver work OK but those
on the remote controller
don't?
Can't use the remote con-
troller with other AV com-
ponents?
Possible cause
The level of the surround back speaker is set
at minimum.
The Surround Back setting is set to None in
the Speaker Configuration.
The selected listening mode doesn't use the
surround back speakers.
Surround speaker output depends on the
source material, and some material may not
use the surround speakers much.
The audio connecting cables at the rear of
the AV Receiver are too close to the power
cord.
The treble is set too high.
The Subwoofer setting is set to No in the
Speaker Configuration.
The volume of the subwoofer is set at mini-
mum.
Speaker set A is turned off. The subwoofer
output does not work while only speaker set
B is on.
The Pure Audio listening mode is selected.
The TV's input selector is set incorrectly.
The video input and output are different for-
mats.
The wrong remote controller mode is
selected.
The batteries are installed incorrectly.
You're not pointing the remote controller at
the AV Receiver's remote sensor.
You've connected a MiniDisc recorder or
CD recorder to the AV Receiver but haven't
changed the TAPE/MD/CDR display.
The wrong remote control code has been
entered.
You're pointing the remote controller at the
wrong AV component.
You've made an connection but not an
analog audio connection (RCA).
Remedy
Check the volume of the surround back
speaker (page 49).
Check the Surround Back setting in the
Speaker Configuration (page 32).
Select another listening mode. See page 42
for information on listening modes.
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).
Untangle the audio cables and position them
as far away as possible from the power cord.
Adjust the treble (page 38).
Check the Subwoofer setting in the Speaker
Configuration (page 32).
Check the volume of the subwoofer
(page 49, 35).
Turn on speaker set A.
When this mode is selected, the display and
the internal video circuits are all turned off
and no video signals are output.
Select the correct input on the TV (i.e., the
input to which the AV Receiver is con-
nected).
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.
Select the correct mode (page 10).
Check the batteries and correct as necessary
(page 9).
Point the remote controller at the AV
Receiver's remote sensor (page 9).
Press and hold the [TAPE] input selector
button until MD or CDR, as appropriate,
appears on the display.
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.
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)
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).
