  John HunterJul 30, 2025
  If your LG OLED TV picture is broken or freezing, you should first check the RF signal level using a digital signal level meter. Also, verify the RF cable connection by reconnecting it or installing a booster. Check other equipment by connecting the RF cable to a DVD player, set-top box, or another TV. Consider a software upgrade. If problems persist, it may be necessary to replace the Main Board.
