  If your LG LED TV has normal audio but no video, there are several things you can check: * Ensure all cables between the boards are properly inserted. * Check the backlight and the power supply. * Verify the Power Board 13V output. If these steps don't resolve the issue, you may need to repair the power board or its parts, replace the inverter, T-con/Main board or module.
