What to do if my LG 60UM6900PUA has normal audio but no video?

If your LG LED TV has sound but no picture, try these steps: Ensure all cables between the boards are properly connected. Check the backlight and power supply. Verify the Power Board 13.2V output. If problems persist, consider replacing the T-con or Main Board, or repairing the Power Board or its components.
