Had Samsung tvs for many years, intact we have 4 Samsung tvs in our house. I got a new one for my sons ps4 which shows blue flashing lines every time you switch the tv on when using ps4. Samsung helpline are useless and don't listen. I've plugged two ps4 consoles into it with blue lines a pic with blue lines. I tried to other Samsung tvs in the home with not a problem. I've sent pics to Samsung and now a month on they want video footage. They said its my console even tho I've told them what ever I plug into it, it causes blue flashing lines, with same cables and devices in any other tv and no problems. Never again will I buy from samsung, I will be taking legal action
