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 your Onkyo dealer.

Power

Can’t turn on the AV receiver

Make sure that the power cord is plugged into the wall outlet properly.

Unplug the power cord from the wall outlet, wait 5 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. Disconnect all speaker cables and input sources, and leave the AV receiver with its power cord discon- nected 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 your Onkyo dealer.

Audio

There’s no sound or it’s very quiet

Make sure that the digital input source is selected properly (page 45).

Make sure that all audio connecting plugs are pushed in all the way (page 24).

Make sure that the polarity of the speaker cables is correct, and that the bare wire is in contact with metal part of each speaker terminal (page 21)

Make sure that the speaker cables are not shorting.

Check the volume (page 48). The AV receiver is designed for home theater enjoyment and has a wide volume range for precise adjustment.

If the MUTING indicator is shown on the display, press the remote controller’s [MUTING] button to unmute the AV receiver (page 58).

While a pair of headphones is connected to the PHONES jack, no sound is output by the speakers (page 59).

Check the digital audio output settings on the con- nected device. On some games consoles, such as those that can play DVDs, the default setting is off.

With some DVD-Video discs, you need to select an audio format from a menu.

If your turntable uses an MC cartridge, you must con- nect an MC head amp, or an MC transformer

(page 35).

Check the speaker settings (pages 70–75).

The input signal format is set to PCM or DTS. Set it to Auto (page 80).

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.

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 when the Output Sp setting is set to Front (page 68).

Make sure the speakers are configured correctly (pages 70, 71).

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.

In the Mono listening mode, only the center speaker outputs sound when the Output Sp setting is set to Center (page 68).

Make sure the speakers are configured correctly (pages 70, 71).

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 (pages 70, 71).

The center speaker produces no sound

When the Stereo listening mode is selected, the center speaker produces no sound.

In the Mono listening mode, only the front speakers output sound when the Output Sp setting is set to Front (page 68).

Make sure the speakers are configured correctly (pages 70, 71).

The surround back speakers produce no sound

The surround back speakers are not used with all lis- tening modes. Select another listening mode

(page 60).

Not much sound may be produced by the surround back speakers with some sources.

Make sure the speakers are configured correctly (pages 70, 71).
