And ALSO APPARENTLY NOBODY FLUFFING KNOWS THAT HDMI PORTS DO GO BAD AND USUALLY ITS THE FLUFFING SOUND THAT STOPS WORKING FIRST WHICH WILL TOTALLY MAKES U THINK ITS UR DEVICE ALSO AND THATS WHAT IT SOUNDS LIKE IS HAPPENING IS THAT UR HDMI PORTS R BAD TRY SWITCHING TO ANOTHER PORT, EVEN THOUGH WHEN IT HAPPENED TO ME ALL MY PORTS ON MY TV WET OUT ONE AFTER ANOTHER AFTER ANOTHER BACK TO FLUFFING BACK ALL 4 OF THEM!?!!??!! SO TRY SWITCHING UR HDMI PORTS AND PLUG SOMETHING ELSE INTO IT TO MAKE SURE ITS WORKING EVEN THOUGH IT WILL INTERMITTENTLY WORK ALSO SO YEAH ITS A PAIN IN THE BUTT TO DIAGNOSE AND TO FIGURE IT OUT ESPECIALLY WHEN THE SOUND GOES OUT FIRST BUT WOULD RANDOMLY START WORKING AGAIN TOTALLY THOUGHT IT WAS MY AMAZON PRIME STICK OR REMOTE THAT WAS FLUFFED UP BECAUSE I NEVER EVER IN MY WILDEST DREAMS EVEN KNEW THAT AN HDMI PORT COULD EVEN GO BAD AT ALL... SOOO ID CHECK THAT OUT FIRST BEFORE REPLACING STUFF ON UR SWITCH BECAUSE I NEVER KNOW IT COULD BE THE TV AND NOT THE SWITCH
