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. Disconnect all speaker cables and input sources, and leave the AV receiver with its power cord discon- nected for one hour. After that, reconnect the power cord, and then set the volume to maximum. If the AV receiver stays on, set the volume to minimum, discon- nect the power cord, and reconnect your speakers and input sources properly. 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 31). Press the [DIGITAL INPUT] but- ton repeatedly.

•Make sure that all audio connecting plugs are pushed in all the way (page 20).

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

•Make sure that the speaker cables are not shorting.

•Check the volume. It can be set to MIN, 1 through 79, or MAX (page 34). 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 38).

•While a pair of headphones is connected to the PHONES jack, no sound is output by the speakers (page 39).

•Check the digital audio output setting 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 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 con- nect an MC head amp, or an MC transformer and a phono preamp.

•Specify the speaker distances and adjust the individual speaker levels (pages 48, 49).

•The input signal format is set to PCM or DTS. Set it to Auto (page 49).

Only the front speakers produce sound?

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

•Make sure the speakers are conﬁgured correctly (page 32).

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.

•Make sure the speakers are conﬁgured correctly (page 32).

The surround speakers produce no sound?

•When the Stereo or Mono listening mode is selected, the surround speakers produce no sound (page 40).

•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 32).

The center speaker produces no sound?

•When the Stereo or Mono listening mode is selected, the center speaker produces no sound (page 40).

•Make sure the speakers are conﬁgured correctly (page 32).

The surround back speaker produces no sound?

•The surround back speaker is not used with all listen- ing modes. Select another listening mode (page 40).

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

•Make sure the speakers are conﬁgured correctly (page 32).

The subwoofer produces no sound?

•The subwoofer outputs no sound while only speaker set B is on. Turn on speaker set A.

•When you play source material that contains no infor- mation in the LFE channel, the subwoofer produces no sound.

•Make sure the speakers are conﬁgured correctly (page 32).

•If the multichannel DVD input is selected and speaker set B is on, speaker set A is reduced to 2-channel play- back, so the subwoofer outputs no sound.
