  Nicole ChristensenAug 7, 2025
  If the Denon Receiver display is lit but no sound is coming out, several things could be the reason: * Check that the speaker cords are securely connected. * Ensure the audio function button is set correctly. * Increase the volume, as it might be set to the minimum. * Turn off MUTING, if it’s on. * If using digital signals, ensure they are being input correctly or that the correct input jacks are selected.

  If your Denon Receiver isn't responding to the remote control, here's what you can check: 1. Replace the batteries with new ones, as the current ones may be dead. 2. Make sure you're close enough to the unit; the remote might be too far away. 3. Remove any obstacles between the remote and the receiver. 4. Ensure you're pressing the correct button. 5. Verify that the batteries are inserted correctly, with the < and > ends in the proper orientation.
