If the test picture is displayed normally, it is likely that the broadcast signal has a problem.
If the problem does not occur in the picture test, please contact the set-top service provider. (e.g., cable TV, Skylife, IPTV)
If the problem persists in the picture test, please contact LG Electronics Service Center.
