What to Check First

  1. If possible, test the sound device (TV or Home Theater System) with a different input to ensure the volume is at an adequate level, and is indeed working.
  2. Check that the sound device is tuned to the proper input. The audio wire should be connected into the corresponding audio-in port.
  3. Test the media you're trying to watch in a different device to make sure the audio is working properly elsewhere.
  4. Does the Blu-ray Player's video play? (only the audio is missing?) Yes No.
  5. Make sure the Blu-ray Player is powered on. If it will not power on, refer to Device Has No Power .
  6. Make sure the sound device (TV or Home Theater System) is powered on, tuned to the correct input, and that the wires are securely plugged in.
  7. Try a different cable (usually HDMI), your wire may have stopped working.
  8. If the issue persists, Scedule a Repair .
  9. Are you using a separate wire for your audio? (HDMI carries audio and video, optical/digital coaxial carry sound only) Yes No.
  10. Using a separate audio wire implies the use of a Home Theater System, Sound Plate, or Sound Bar. Make sure the Audio device is set to the correct input.

Why This Can Happen

Symptoms can have more than one cause, and the correct steps depend on the exact model, installation and operating conditions. Use the checks above to narrow the issue before service.
