I've replaced the power supply in several. That was all that was wrong with them. Dang switching power supplies. I was given a Samsung because it had vertical lines in the screen. Got worse when I tried to fix it. I'm not sure any of them are bullet proof. They are nearly to the point of being disposable. I'm about to buy one for the living room at least 60". I'm just going to buy the cheapest 4k that has a decent picture and plug it into a surge suppressor. I'll plug firestick in it if it doesn't have what I want to watch.
