The first thing would be to check all cable conections, and then try a reset.Unplug your tv and cable box or whatever provider you have for 10 seconds or so, then plug it back in. See if that works.If not try a hard reset, unplug tv and cable box for at least 4 hours or overnite. If that doesn't help then the touble internal, (bad caps) ??.Your tv is just not getting a signal to display on the screen I would just hook the tv to cable and see if that works.
