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.

Power

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.

Audio

There’s no sound, or it’s very quiet?

Make sure that all audio connecting plugs are pushed in all the way (page 20).

Make sure that the inputs and outputs of all compo- nents are connected properly (page 20).

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 22)

Make sure that the input source is properly selected (page 44).

Make sure that the speaker cables are not shorting.

Check the volume. It can be set to MIN, 1 through 99, or MAX (page 44). 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 45).

While a pair of headphones is connected to the Phones jack, no sound is output by the speakers (page 45).

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.

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 con- nect an MC head amp, or an MC transformer and phono equalizer.

Make sure that none of the connecting cables are bent, twisted, or damaged.

Not all listening modes use all speakers (page 51).

Specify the speaker distances (page 41) and adjust the individual speaker levels (page 42).

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 listening mode is selected, only the front speakers produce sound.

Make sure the speakers are configured correctly (page 39).

Only the center speaker produces sound?

If you use the Pro Logic II Movie or Pro Logic II 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 39).

The surround speakers produce no sound?

When the Stereo or Direct, listening mode is selected, the surround speakers produce no sound (page 51).

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 39).

The center speaker produces no sound?

When the Mono, Stereo, Direct, or Orchestra listening mode is selected, the center speaker produces no sound (page 51).

Make sure the speakers are configured correctly (page 39).
