Troubleshooting

Before starting the procedure

Problems may be solved by simply turning the

power on/off or disconnecting/connecting the

power cord, which is easier than working on the

connection, setting and operating procedure. Try

the simple measures on both the unit and the

connected device. If the problem is that the video

or audio is not output or the HDMI linked operation

does not work, disconnecting/connecting the HDMI

cable may solve it. When reconnecting, be careful

not to wind the HDMI cable since if wound the

HDMI cable may not fit well. After reconnecting, turn

off and on the unit and the connected device.

The AV receiver turns off unexpectedly�

● The AV receiver will automatically enter standby mode when

Auto Standby or Sleep Timer is set and launched.

● The protection circuit may have been activated. If this is the

case, when you turn the unit on again, "AMP Diag Mode" will

appear on the main unit’s display. The unit will then enter a

mode that detects abnormal conditions. If no problems are

detected, "AMP Diag Mode" will disappear and the unit will

return to a normal state. If "CHECK SP WIRE" appears on the

display, the speaker cables may be short-circuited. Turn the

unit off, and check to see if the cable core of any of the speaker

cables is in contact with that of another speaker cable or with

the rear panel. After that, turn the unit on again. If "NG" appears,

unplug the power cord immediately and contact your Onkyo

dealer.

There’s no sound, or it’s very quiet�

● A wrong input selector button has been selected. Select a

correct input for the player. Also check that muting is not on.

● Not all listening modes use all speakers.

There’s no picture�

● A wrong input selector button has been selected.

● To display video from the connected player on the TV screen

while the unit is in standby, you need to enable HDMI Standby

Through function.

● When the TV image is blurry or unclear, power cord or

connection cables of the unit may have interfered. In that case,

keep distance between TV antenna cable and cables of the unit.

Video and audio are out of synch�

● Video may be delayed relative to audio depending on the

settings and connections with your TV. Adjust in "Step 3:

Playing Back", "4 Quick Setup Menu", "A/V Sync".

Cannot play digital surround�

● To enjoy digital surround sound including Dolby Digital and

DTS, audio output should be set to "Bitstream output" on the

connected Blu-ray Disc Player or other device.

Cannot output audio such as Dolby Atmos according

to the format of the source�

● If you cannot output audio according to the format of the

source (Dolby TrueHD, Dolby Atmos, DTS-HD Master Audio,

etc.), in the Blu-ray Disc Player settings try setting "BD video

supplementary sound" (or secondary sound) to "Off". Change

the listening mode for each source after changing the setting to

confirm.

HDMI control does not function correctly�

● Set the CEC link function of the unit to on. It is also necessary

to make the HDMI linked system setting on the TV. See the TV's

instruction manual for details.

 Resetting the unit

Resetting the unit to the status at the time of shipment may solve

the problem. If the measures above do not solve the problem, reset

the unit with the following procedure. If you reset the unit status,

your preferences will be reset to the defaults. Note them down

before starting reset.

1�

While holding down CBL/SAT on the main unit (note that

step 2 must be performed with this button pressed down)

2� Press zON/STANDBY on the main unit� ("Clear" appears on

the display and the unit returns to standby�)

● Do not unplug the power cord until "Clear" disappears from

the display.
