Troubleshooting

If you have any trouble using the AV receiver, look for a solution in this section. If you can’t resolve the issue your- self, contact your Onkyo dealer.

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

To reset the AV receiver to its factory defaults, turn it on and, while holding down VCR/DVR, press ON/ STANDBY. “Clear” will appear on the display and the AV receiver will enter Standby mode.

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

RECEIVER

AUDIO

To reset the remote controller to its factory defaults, while holding down RECEIVER, press and hold down AUDIO until the remote indicator lights (about 3 sec- onds). Within 30 seconds, press RECEIVER

again.

The on-screen setup menus appear only on a TV that is connected to the HDMI OUT. If your TV is con- nected to the MONITOR OUT V or the COMPO- NENT VIDEO OUT, use the AV receiver’s display when changing settings.

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 STANDBY indicator flashes red

The protection circuitry has been activated.

Remove the power cord from the wall outlet immedi-

 

ately. Disconnect all speaker cables and input

 

sources, and then leave the AV receiver with its

 

power cord disconnected for 1 hour. After that,

 

reconnect the power cord and set the volume to max-

 

imum. If the AV receiver stays on, set then the vol-

 

ume to minimum, disconnect the power cord, and

 

reconnect your speakers and input sources. If the AV

 

receiver turns off when you set the volume to maxi-

 

mum, disconnect the power cord, and contact your

 

Onkyo dealer.

There’s no sound, or it’s very quiet

Press SPEAKERS A or B to turn on the indicator

properly.

 

Make sure that all audio connecting plugs are pushed

15

in all the way.

 

 

 

Make sure that the inputs and outputs of all compo-

16-18

nents are connected properly.

 

Make sure that the polarity of the speaker cables is

12

correct, and that the bare wires are in contact with

 

the metal part of each speaker terminal.

 

 

 

Make sure that the input source is properly selected.

Check the volume. The AV receiver is designed for

home theater enjoyment. It has a wide volume range,

 

allowing precise adjustment.

 

If the MUTING indicator is flashing on the display,

22

press the remote controller’s MUTING to unmute

 

the AV receiver.

 

 

 

While a pair of headphones is connected to the

22

PHONES jack, no sound is output by the speakers.

 

If there’s no sound from a DVD player connected to

an HDMI IN, check the DVD player’s output set-

 

tings, and be sure to select a supported audio format.

 

 

 

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 uses an MC cartridge, you must

connect an MC head amp, or an MC transformer.

 

Make sure that none of the connecting cables are

bent, twisted, or damaged.

 

 

 

Not all listening modes use all speakers.

26

Specify the speaker distances and adjust the individ-

31

ual speaker levels.

 

 

 

The input signal format is set to “PCM” or “DTS”.
