This seems to be fake.
First, why is the guy recording? Second, it seems rather fortunate that the camera was placed at an angle that captured the offense. That’s lucky right there. Third, this isn’t Samsung’s technician this is an authorized repair person. He would make more money repairing the TV than attempting to deny service to the customer. Fourth, is the video proclaiming that Samsung is telling their authorized repair centers to damage customers tv sets? How many reputable repair centers do you think would have already contacted the media?
Or, maybe the internet has me too jaded. I dunno.
