  Gary WardAug 27, 2025
  If your Denon AVR-789 Receiver is shutting down abruptly and the power indicator flashes red at approximately 2-second intervals, it's likely that the protection circuit has been activated due to a temperature rise in the unit's internal components. To address this: * Immediately switch off the power. * Allow the unit to cool down sufficiently before reapplying power. * Reinstall the AVR-789 in a location with better ventilation.

  Marc SanchezAug 26, 2025
  If your Denon AVR-789 Receiver suddenly powers off and the power indicator flashes red at short intervals, it could be due to: * Using speakers with impedance lower than specified. * Speaker cable core wires touching each other or disconnecting and contacting the AVR-789 rear panel. To resolve this: * Use speakers with the correct impedance. * Unplug the power cord and correct any issues with the speaker wires (twisting them tightly or re-terminating), then reconnect.
