  Philip StephensAug 12, 2025
  If you have normal audio but no video on your LG OLED TV, there are several potential causes and solutions. First, ensure that all cables between the boards are properly inserted. You may also need to check the Vx1 lock. If the issue persists, inspect the power board. If there's 0V output to the Main board, replace the Main board. If the Power Board is outputting to the Module, replace the Power Board or repair the parts. As a last resort, consider replacing the Module.

  Jonathan RobertsonAug 27, 2025
  If your LG OLED TV shows no image and produces no sound, ensure the TV is turned on and the power cord is securely connected to a working wall outlet. Test the outlet with another device to confirm it's functioning correctly. Also, ensure that your Access Point (AP) is located more than 0.2 m (0.65 ft) away from the TV.

  If you notice a slight flicker when turning on your LG OLED TV and the TV feels cold, this is normal. Avoid touching the screen or holding your finger against it for extended periods. Small dots on the screen are deactivated pixels and do not impact the TV's performance.

Why does my LG OLED65B9PUA make sounds?

  Joel WilsonSep 7, 2025
  A cracking noise from your LG OLED TV during use or when turning it off is typically due to plastic thermal contraction caused by temperature and humidity changes. Additionally, a low-level noise may come from the high-speed switching circuit that provides power to operate the TV.
