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 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.
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 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.
The tone controls have no effect
• If the DIRECT indicator or PURE AUDIO indicator
lights up, the tone controls have no effect. Press the
[DIRECT] button or [PURE AUDIO] button to turn
the function off. The DIRECT or PURE AUDIO indi-
cator will go off (page 25).
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.
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 [VCR/DVR] button,
press the [ON/STANDBY] button.
Note that resetting the receiver will delete your radio
presets and custom settings.
