- What video devices/ sources (such as cable box DVD player etc) are connected to TV and does the problem occur on all video input sources?- Have you tried to unplug TV and cable box power cords from wall outlet for 10 minutes to reset, replug back in, let cable box reboot that may take several minutes and check?If not yet, can you try it now and reply back with the result?
