What to do if there is no video but normal audio on my LG 43UJ6300 LED TV?
- V
  Victoria McdanielJul 27, 2025
  If you have normal audio but no video on your LG LED TV, several components could be at fault. First, ensure all cables between the boards (Main B/D, Power B/D, LVDS Cable, Speaker Cable, IR B/D Cable) are properly inserted. If the connections are secure, check the backlight. Also, verify the Power Board voltage is at 13V. If these steps don't resolve the issue, consider replacing the T-con/Main Board or module, repairing the Power Board or its parts, or replacing the Inverter.
