Troubleshooting
If you have any trouble using the AV receiver, look for a
solution in this section. If you can’t resolve the issue
yourself, contact the dealer from whom you purchased
this unit.
Can’t turn on the AV receiver?
• Make sure that the power cord is properly plugged into
the wall outlet.
• Unplug the power cord from the wall outlet, wait five
seconds or more, then plug it in again.
The AV receiver turns off as soon as it’s turned
on?
• The amp protection circuit has been activated.
Remove the power cord from the wall outlet immedi-
ately and contact the dealer from whom you purchased
this unit.
There’s no sound, or it’s very quiet?
• Make sure that all audio connecting plugs are pushed
in all the way (page 21).
• Make sure that the inputs and outputs of all compo-
nents are connected properly (page 21).
• Make sure that the polarity of the speaker cables is
correct, and that the bare wires are in contact with
metal part of each speaker terminal (page 23)
• Make sure that the input source is properly selected
(page 53).
• Make sure that the speaker cables are not shorting.
• Check the volume. It can be set to MIN, 1 through 99,
or MAX (page 53). The AV receiver is designed for
home theater enjoyment. It has a wide volume range,
allowing precise adjustment.
• If the MUTING indicator is shown on the display,
press the remote controller’s [Muting] button to
unmute the AV receiver (page 54).
• While a pair of headphones is connected to the Phones
jack, no sound is output by the speakers (page 54).
• 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.
•For the DTR-5.5, if your turntable doesn’t have a
built-in phono preamp, you must connect one between
it and the AV receiver. If your turntable uses an MC
cartridge, you must connect an MC head amp, or an
MC transformer and phono equalizer.
•For the DTR-6.5, if your turntable uses an MC car-
tridge, you must connect an MC head amp or an MC
transformer (see page 36).
• Make sure that none of the connecting cables are bent,
twisted, or damaged.
• Not all listening modes use all speakers (page 60).
• Specify the speaker distances (page 48) and adjust the
individual speaker levels (page 50).
• Make sure that the speaker setup microphone is not
still connected.
Only the front speakers produce sound?
• When the Stereo listening mode is selected, only the
front speakers and subwoofer produce sound.
• When the Direct or Pure Audio listening mode is
selected, only the front speakers produce sound.

(page 46).
Only the center speaker produces sound?
• If you use the Pro Logic IIx Movie or Pro Logic IIx
Music listening mode with a mono source, such as an
AM radio station or mono TV program, the sound is
concentrated in the center speaker.
• Make sure the speakers are configured correctly
(page 46).
The surround speakers produce no sound?
• When the Stereo, Direct, or Pure Audio listening mode
is selected, the surround speakers produce no sound
(page 60).
• Depending on the source and current listening mode,
not much sound may be produced by the surround
speakers. Try selecting another listening mode.
• Make sure the speakers are configured correctly
(page 46).
The center speaker produces no sound?
• When the Mono, Stereo, Direct, Pure Audio, or
Orchestra listening mode is selected, the center
speaker produces no sound (page 61).
• Make sure the speakers are configured correctly
(page 46).

sound?

tening modes. Select another listening mode
