A:AnswerI have not had that problem. Most likely it is how much speed you have on your internet site. If your running more tvs, computers our gaming games that will make your tv go in and out. Make sure no one else in the family is using another tv or playing games. It is the signal the tv is getting from your router that controls the tv. I got 1000 speed on my internet because my wife works from home.
A:AnswerMine receives all apps so far. Netflix, Prime Vidio, Max have all increased their output. So if you have an older Samsung it doesn’t meet their requirements. Just like computers. Window 10 will not run on older computers because of speed it receives.
A:AnswerCalled the store about warranty. The white line is the light tubes an I had an older tv do that. It can be fixed but it would be better to get a new one. If you have the manual on your tv look at the warranty and called them unless you bought a extended warranty from best buy.
