What to do if no sound from surround speakers on Denon Receiver?
If you're not hearing any sound from your surround speakers, it might be because the surround mode is set to “STEREO”, “DIRECT”, or “PURE DIRECT”. Change the setting to a surround playback mode.
Why does my Denon AVR-789 Receiver power off suddenly and the power indicator flashes red?
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.
Why no sound from subwoofer connected to Denon AVR-789?
If you're not getting any sound from the subwoofer connected to your Denon Receiver, check the following: * Ensure the subwoofer is powered on. * Verify that the “Subwoofer” setting in “Speaker Configuration” is set to “Yes”. * Confirm the subwoofer is properly connected. * Check that the subwoofer's volume is not turned down or off. Adjust the subwoofer's volume to an appropriate level.
What to do if Denon AVR-789 Receiver power switches off suddenly and power indicator flashes red?
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.
