The TV makes a creaking, crackling, or popping noise
A creaking, crackling, or popping sound from your TV is normal and is not a malfunction.
These sounds occur when parts expand or contract slightly due to temperature changes in the room or the TV.
For example, you may hear the sound when your TV is turned on or off.
The sound location may change or become less noticeable due to environmental changes such as temperature or humidity.
