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.

If you can’t resolve the issue yourself, try resetting the AV receiver before contacting your Onkyo 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 plugged into the wall outlet properly.

Unplug the power cord from the wall outlet, wait 5 seconds or more, then plug it back 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. Disconnect 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 your Onkyo dealer.

Audio

There’s no sound or it’s very quiet

Press the SPEAKERS [A] or [B] button to turn on the indicator for the speakers that you want to output sound.

HDMI audio is passed through the AV receiver and can only be heard from your TV.

To listen to an audio source that’s connected to an OPTICAL or COAXIAL input, make sure that input is assigned to an input selector (page 36).

Make sure that all audio connecting plugs are pushed in all the way (page 18).

Make sure that the polarity of the speaker cables is correct, and that the bare wire is in contact with the metal part of each speaker terminal (page 14).

Make sure that the speaker cables are not shorting.

Check the volume (page 38). The AV receiver is designed for home theater enjoyment and has a wide volume range for precise adjustment.

If the MUTING indicator is flashing on the display, press the remote controller’s [MUTING] button to unmute the AV receiver (page 39).

While a pair of headphones is connected to the PHONES jack, no sound is output by the main room speakers (page 40).

Check the digital audio output settings on the source component. On some game 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 or with the [AUDIO] button on your DVD player’s remote controller.

If your turntable doesn’t have a phono preamp built- in, 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 a phono preamp.

Check the speaker settings (pages 54–56).

If the digital signal format is set to PCM or DTS, set it to “Auto” (page 41).

Only the front speakers produce sound

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

Check the “3. Sp Config” (page 54).

Only the center speaker produces sound

If you use the Dolby Pro Logic II Movie or Dolby Pro Logic II Music listening mode with a mono source, such as an AM radio station or mono TV program, the sound will be concentrated in the center speaker.

Check the “3. Sp Config” (page 54).

The center speaker produces no sound

When the Stereo or Mono listening mode is selected, the center speaker produces no sound (page 53).

Check the “3. Sp Config” (page 54).

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 the current listening mode, not much sound may be produced by the surround speakers. Try another listening mode (page 49).

Check the “3. Sp Config” (page 54).
