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 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 your Onkyo dealer.

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 the metal part of each speaker terminal (page 22).

•Make sure that the input source is properly selected (page 51).

•Make sure that the speaker cables are not shorting.

•Check the volume. It can be set to MIN, 1 through 99, or MAX (page 51). 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 52).

•While a pair of headphones is connected to the PHONES jack, no sound is output by the speakers (page 52).

•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 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 connect 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 62).

•Specify the speaker distances (page 47) and adjust the individual speaker levels (page 48).

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

Only the front speakers produce sound?

•Make sure the speakers are configured correctly (page 44).

Only the center speaker produces sound?

•Make sure the speakers are configured correctly (page 44).

The surround speakers produce no sound?

•When the Stereo or Direct listening mode is selected, the surround speakers produce no sound (page 62).

•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 44).

The center speaker produces no sound?
