Why my LG 15LU766A makes sounds?
- RRobert BoydSep 12, 2025
The cracking noise you hear when watching or turning off your LG LED TV is due to plastic thermal contraction caused by temperature and humidity. A low-level noise can also be generated from a high-speed switching circuit that supplies a large amount of current to operate the TV.
