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.
To reset the remote controller to its factory defaults,
while holding down RECEIVER, press and hold down
HOME until RECEIVER button lights (about

again.
The on-screen menus appear only on a TV that is
connected to the
HDMI OUT MAIN. If your TV is
connected to other video outputs, use the AV
receiver’s display when changing settings.
