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.

If you can’t resolve the issue yourself, try resetting the AV receiver before contacting the dealer.

To reset the AV receiver to its factory defaults, turn it on and, while holding down the [VCR/DVR] button, press the [On/Standby] button. “Clear” will appear on the display and the AV receiver will enter Standby mode.

Note that resetting the AV receiver will delete your radio presets and custom settings.

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 immediately. Discon- nect all speaker cables and input sources, and leave the AV receiver with its power cord disconnected for 1 hour. After that, reconnect the power cord and set the volume to maximum. If the AV receiver stays on, set the volume to minimum, disconnect the power cord, and reconnect your speakers and input sources. If the AV receiver turns off when you set the volume to maximum, disconnect the power cord, and contact the dealer.

Audio

There’s no sound, or it’s very quiet

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

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 24-37).

Make sure that the polarity of the speaker cables is correct, and that the bare wires are in contact with the metal part of each speaker terminal (page 17).

Make sure that the input source is properly selected (page 54).

Make sure that the speaker cables are not shorting.

Check the volume. It can be set to dB, 81.5 dB through +18.0 dB (page 54). The AV receiver is

designed for home theater enjoyment. It has a wide volume range, allowing precise adjustment.

While a pair of headphones is connected to the Phones jack, no sound is output by the speakers (page 56).

If there’s no sound from a DVD player connected to an HDMI IN, check the DVD player’s output settings, and be sure to select a supported audio format.

Check the digital audio output setting on the con- nected device. On some game 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 uses an MC cartridge, you must con- nect an MC head amp, or an MC transformer.

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

Not all listening modes use all speakers (page 86).

Specify the speaker distances (page 93) and adjust the individual speaker levels (page 94).

Make sure that the speaker setup microphone is not still connected.

The input signal format is set to PCM or DTS. Set it to Auto (page 113).

Only the front speakers produce sound

When the Stereo listening mode is selected, only the front speakers and subwoofer produce sound.

In the Mono listening mode, only the front speakers output sound if the “Output Speaker” setting is set to “Left/Right” (page 98).

Check the Speaker Configuration (page 90).

Only the center speaker produces sound

If you use the Dolby Pro Logic IIx Movie, Dolby Pro Logic IIx Music, or Dolby Pro Logic IIx Game listen- ing mode with a mono source, such as an AM radio station or mono TV program, the sound is concen- trated in the center speaker.

In the Mono listening mode, only the front speakers output sound if the “Output Speaker” setting is set to “Center” (page 98).

Make sure the speakers are configured correctly (page 90).

The surround speakers produce no sound

When the Stereo or Mono listening mode is selected, the surround speakers produce no sound.

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 90).
