A-9150 - Troubleshooting: External Components and Connections

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.

No sound is heard from a connected component.

• Make sure the correct input source is selected.
• Make sure the analog audio cable is connected correctly.

When the RI interlock does not function properly

• Check that each device is connected correctly and that the
  RI MODE is set correctly.
• The connecting method may vary depending on the device
  that will be connected. Please refer to the RI connection
  section in the owner’s manual of the connected device.

The sound from turntable is distorted.

• If your turntable has a built-in phono preamp, connect to
  other analog inputs such as LINE IN.
• If your turntable does not have a built-in phono preamp,
  connect a turntable to PHONO.
• Make sure that the ground wire is connected. Otherwise, it
  may produce an audible hum and noise.
• Confirm that the MM/MC input setting is correct for the
  type of cartridge in the turntable.
