These a called transmission bars and as such are nothing to do with your TV a amplifier may do the trick and reduce them a little but the fault rests firmly with the Broadcaster.
I'v bought 40 inch es6100 a mont ago. It has some clouding, but I understand that's the "charm" od edge lit LED TV's. But there's another issue. I noticed horizontal banding visible on completely dark-gray screen, so as while watching movies/playing games when camera moves horizontaly. I phoned my local Samsung division (I'm from Poland), described the issue and was informed that it's within the specyfication of edge lit LED sets. Am I really stuck with the problem? It isn't severe, but it anoys me especially when playing video games.
