Troubleshooting

If you have any trouble using the receiver, look for a

solution in this section.

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 immediately.

Disconnect all speaker cables and input sources, and

leave the receiver with its power cord disconnected 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.

There’s no sound or it’s very quiet

• Make sure the speaker set A or B is on (page 20).

• Make sure that all audio connecting plugs are pushed

in all the way (pages 12-18).

• 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 12).

• 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 20).

• If the MUTING indicator is shown on the display,

press the remote controller’s [MUTING] button to

unmute the receiver (page 21).

• If your turntable doesn’t have a phono preamp built-

in, you must connect one between it and the receiver.

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.

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 26).

• 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.

Power

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 [LINE 2] button,

press the [ON/STANDBY] button.

“Clear” will appear on the display and the receiver

will enter Standby mode.

Note that resetting the receiver will delete your radio

presets and custom settings.
