Troubleshooting

If you have any trouble using the receiver, look for a solution in this section.

If you can’t resolve the issue yourself, try resetting the receiver before contacting your Onkyo dealer.

To reset the receiver to its factory defaults, turn it on and, while holding down the [VCR/DVR] button, press the [ON/STANDBY] button.

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

Power

Can’t turn on the 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 STANDBY indicator is flashing

•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 receiver with its power cord discon- nected for 1 hour. After that, reconnect the power cord and press the [ON/STANDBY] button again. If you can not resolve the problem, contact your Onkyo dealer.

Audio

There’s no sound or it’s very quiet

•Make sure the speaker set A or B is on (page 23).

•Make sure that all audio connecting plugs are pushed in all the way (pages 13-21).

•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 13).

•Make sure that the speaker cables are not shorting.

•Make sure that the inputs and outputs of all compo- nents are connected properly.

•Make sure that the correct input source is selected (page 23).

•If the MUTING indicator is shown on the display, press the remote controller’s [MUTING] button to unmute the receiver (page 24).

•If your turntable uses an MC cartridge, you must con- nect an MC head amp, or an MC transformer and a phono preamp.

Noise can be heard

•Using cable ties to bundle audio cables with power cords, speaker cables, and so on may degrade the audio performance, so don’t do it.

•An audio cable may be picking up interference. Try repositioning your cables.

The tone controls have no effect

•If the DIRECT indicator or PURE AUDIO indicator lights up, the tone controls have no effect (page 25).

Tuner

Reception is noisy, stereo FM reception suffers from hiss, or the FM STEREO indicator doesn’t appear

•Relocate your antenna.

•Move the receiver away from your TV or computer.

•Listen to the station in mono (page 29).

•When listening to an AM station, operating the remote controller may cause noise.

•Passing cars and airplanes can cause interference.

•Concrete walls weaken radio signals.

•If nothing improves the reception, install an outdoor antenna.
