Tv keeps flickering on and off
When I turn my DIRECTV STREAM unit and tv on, it shows the picture and sound for 1-2 seconds. But then starts to flicker every 3-8 seconds to a black screen with no sound. I’ve checked all wires to make sure nothing is lose and there is always power to the unit because when it goes blank the lights on the DIRECTV STREAM box and TV are still on. Any suggestions? I JUST got this tv and unit less then 5 months ago!
