So I have a Un58mu6070 and yes I have had it about 3 years but am kinda disappointed that it has developed an issue with the screen flashing on and off. This only happens randomly and very momentary but when I’m gaming or watching a movie it’s very annoying as sometimes it happens so many times that I just give up what I’m doing and move on. This is my first 4K uhd tv and the only Samsung out of 3 that I’m having an issue with. I have tried all the simple fixes and nothing seems to work permanently. My other TVs are older than this unit and I’m fact one survived a tree coming through the house and hitting it during a tornado. I’ve heard a lot of negative reviews and comments on the newer stuff they’re putting out so I’m wondering if it’s time to move on from Samsung?
