Why does my Onkyo A-9130 Amplifier turn off unexpectedly?

  Alexa MosleyAug 14, 2025
  Your Onkyo Amplifier might be turning off unexpectedly due to several reasons: * Auto standby could be activated. * A speaker cable may have shorted, ensure that bare speaker wires aren't touching each other or the back panel, then turn the unit on again. * The unit's temperature may have risen abnormally; ensure the unit has sufficient ventilation and allow it to cool down before turning it on again. * The volume of the connected pre-amplifier is too low, increase the volume on the pre-amplifier.
