I just started having the same(?) issue whenever the Roku box is on. TV works fine via Direct TV satellite. I only use Roku for viewing Netflix and when I do the screen will go black for 2-3 seconds then come back for 2-3 seconds, continuously. Audio is fine. Have tried a hard reset on the box via pin hole and no change.
