I have Samsung 1080p, full HD Version AA02. Someone cut cable wire, lost all internet & cable, TWC repaired it. TV working fine before, turned it on, could only get ROKU, still no service in room, which I did not realize. Tried to go from ROKU back to TV, to Component 1, would not, just snowy screen, tried HDMI
, took me back to ROKU, then went to TV, snowy screen. Turned TV off, tried to reboot, cable box came back on but now TV will not come on at all. Red light does not even light up. Tried another TV there, that is when I found no cable connection, but that TV comes on & will at least play the ROKU, why will the Samsung TV not come on at all?
