What to do if my LG 55SJ8000l has sound but no picture?

If your LG LED TV has normal audio but no video, first, check that all cables between the boards are properly inserted. Then, verify if the backlight is on. Further troubleshooting includes checking the power board voltage (20V, 13.2V, etc.) and the 20V output of the power board. If issues persist, consider repairing the power board or its parts, replacing the inverter, or replacing the T-con/Main Board or module.
