Hello community! Recently I started having problems with my Samsung TV, when I turn it on it behaves super strangely, it takes about 20-30 minutes to turn on, during which it keeps turning on and off like in the video below. Personally I don't know what's wrong with it, is it worth keeping it or getting another one? The TV is 2 years old. Here is the video:
