A-9150 - Troubleshooting: Power

Since the issue may be caused by other components that are connected, be sure to also check them while referring to their manuals.

• Onkyo is not responsible for damages (such as CD rental fees) due to unsuccessful recordings caused by the unit’s malfunction. Before you record important data, make sure that the material will be recorded correctly.
• The integrated amplifier contains a microcomputer for signal processing and control functions. In very rare situations, severe interference, noise from an external source, or static electricity may cause it to lockup. In the unlikely event that this should happen, unplug the power cord, wait at least 5 seconds, and then plug it again.
• Before disconnecting the power cord from the wall outlet, set the integrated amplifier to Standby.
• If during idling the cover is too hot to touch, then ventilation needs to be improved.

Before requesting repairs 

If the integrated amplifier is no longer working or functioning, any issues may be resolved by resetting the microcomputer contained in the integrated amplifier to revert all settings to their defaults. 

Before requesting repairs, follow the procedure below to reset the microcomputer. 

• With the integrated amplifier turned on, hold down DIRECT and press ÍON/STANDBY.

Can’t turn on the Integrated Amplifier

• Make sure that the power cord is properly plugged into the
  wall outlet.
• Unplug the power cord from the wall outlet, wait 5 seconds
  or more, then plug it in again.

The Integrated Amplifier turns off unexpectedly

• When the protection circuit is activated (because of speaker
  short-circuit, overload, or over-current), the integrated
  amplifier enters Standby mode. Remove the source of the
  problem and turn the integrated amplifier back on.
• Check that the switch on the back of the integrated
  amplifier is set to the correct setting.
• The settings are not enabled when the switch is changed
  during the Standby mode.
  To change a setting, be sure to turn on the unit prior to
  making any changes.
• If this unit is being used as a power amplifier and input is
  switched to "MAIN IN", then if the volume of the
  connected pre-amplifier is low, auto standby
  may function and the power may automatically switch to
  standby. If this happens, you may be able to fix it by
  increasing the volume on the pre-amplifier.
