TV is Making a Cracking or Popping Sound - TV - Noise

Some types of noises are normal in an LCD, LED, and/or Plasma Television. You will need to determine the type of noise to properly troubleshoot the issue.


  1. Does the noise get louder as you increase the volume? Yes No
    • The noise may be caused by the cabinet expanding or contracting due to varying temperatures.
    • If the noise is consistent and/or intrusive, Contact Us.
  2. Do you hear the noise on all Inputs/Channels? Yes No
  3. Do you hear the noise while watching live TV or something else, such as a Blu-ray disc or video game? Live TV Other
    • The noise may be vibration due to high volumes or high bass.
    • If you hear the sound only during abnormally loud commercials or action scenes, try to activate the auto-volume feature from the audio menu.
    • If the issue persists, Contact Us.
    • Try to hook a known working device into the same input. If you no longer hear the sound when the other device is hooked up, you may need to replace the cable or the faulty unit itself.
    • If the issue persists, Contact Us.
    • Tune to an HD channel to check if the noise is present there as well.
    • If the sound works well when tuned to other channels, it is likely coming from the program or broadcast station of that channel.
    • If the issue persists, Contact Us.
