Speakers & soundbars

AV receiver has no sound from any speaker

This usually comes down to the wrong input selected, muted output, or incorrect speaker configuration in the receiver's setup menu. Checking the input and mute status first solves most cases.

Difficulty
Moderate
Time
15–30 minutes

Symptoms

  • Receiver display is on but no sound from any speaker
  • Volume knob moves but nothing happens
  • Sound worked before but stopped after a settings change
  • Only some channels/speakers have sound

Likely causes

  • CommonWrong input source selected on the receiverEach connected device (TV, Blu-ray, game console) needs its matching input selected.
  • CommonReceiver muted or volume set to minimumA mute button press or accidental volume-down can silence output entirely.
  • PossibleSpeaker configuration not set correctly in the setup menuIncorrect speaker assignment or a skipped auto-calibration can leave outputs unassigned.
  • PossibleLoose or incorrect speaker wire connectionsSpeaker wires need to go to the correct positive/negative terminals matching the input.
  • Less commonInternal amplifier or protection circuit faultReceivers can enter a protection mode that mutes all output if it detects an internal fault.

What to do

  1. Confirm the correct input is selected on the receiver matching the device you're trying to hear (e.g., 'HDMI 1' for the TV).
  2. Check that mute isn't engaged and volume is turned up to an audible level.
  3. Look at the receiver's front display or app for any error codes or a flashing 'protection' indicator.
  4. Verify speaker wires are connected to the correct positive and negative terminals on both the receiver and speakers.
  5. Run the receiver's automatic speaker setup/calibration if available, or manually check the speaker configuration menu.
  6. Unplug the receiver from power for a full minute, then plug back in and power on before testing again.
  7. Test with headphones plugged into the receiver if available, to check if the receiver itself is producing sound.
  8. Try a single speaker connected directly to isolate whether the issue is the receiver or the speaker wiring.

Tools and parts

  • Screwdriver (for speaker terminals)

When to call a pro

If the receiver shows a persistent protection or error indicator, it likely has an internal amplifier fault and should be serviced by a professional.

Safety

Use caution

Unplug the receiver from power before touching speaker wire terminals to avoid shock or shorting the amplifier.
