Why does my screen go black every few seconds, loses sound with pictur
I turn on tv, get smart screen logo as always, picture, then it goes to black, then smart screen, and just repeats over and over. Sometimes no sound. This started immediately after I set up a smart tv in another room, just a coincidence I'm sure-strange timing! Turned off tv, cable box, unplugged all, changed HDMI cord.. help!
