TVs

TV has picture but no sound

This is almost always a settings, cable, or external speaker issue rather than a broken TV. Check the mute, volume, and audio output setting before assuming a hardware failure.

Symptoms

  • Picture displays normally
  • No audio from TV speakers
  • Volume bar moves but nothing is heard
  • Sound worked before a soundbar or app change

Likely causes

  • CommonTV muted or volume set too lowRemotes get bumped in couch cushions and mute without you noticing.
  • CommonAudio output routed to external speakers or soundbarIf the TV's audio output setting is set to 'external speaker,' internal speakers stay silent.
  • PossibleHDMI-ARC or optical cable issueA loose or faulty cable to a soundbar cuts sound with no error shown.
  • PossibleApp-specific audio bugOne streaming app can lose sound while live TV or another app still has it.

What to do

  1. Press mute to confirm it isn't already muted, then raise the volume with the remote.
  2. Check the TV's sound settings menu for the audio output; set it to 'TV speaker' if no external speaker is connected.
  3. If using a soundbar or receiver, confirm it's powered on and set to the correct input.
  4. Reseat the HDMI-ARC or optical cable at both ends.
  5. Test sound in a different app or on a different input (like a game console) to see if the issue is app-specific.
  6. Restart the TV by unplugging it for 60 seconds.
  7. Update the TV's software if an update is available, since audio bugs are often fixed this way.

When to call a pro

If sound is missing on every app, every input, and after a factory reset, the internal speaker or audio board may need service from a TV repair technician.
