Troubleshooting

If you have any trouble using the AV receiver/AV ampli- fier, 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/AV amplifier before contacting your Onkyo dealer.

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

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

The onscreen setup menus appear only on a TV that is connected to the HDMI OUT. If your TV is connected to the composite video or S-Video MONITOR OUT, or the COMPONENT VIDEO MONITOR OUT, use the AV receiver/AV amplifier’s display when changing settings.

Power

Can’t turn on the AV receiver/AV amplifier

•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/AV amplifier 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/AV amplifier 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/AV amplifier stays on, set the volume to minimum, discon- nect the power cord, and reconnect your speakers and input sources. If the AV receiver/AV amplifier 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 44).

•Make sure that all audio connecting plugs are pushed in all the way (page 22).

•Make sure that the inputs and outputs of all compo- nents are connected properly (page 25-38).

•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 18).

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

•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.

•In the Mono listening mode, only the front speakers output sound if the “Output Speaker” setting is set to “Left/Right” (page 81).

•Check the Speaker Configuration (page 73).

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 81).

•Make sure the speakers are configured correctly (page 73).

The surround speakers produce no sound
