Hello. I’ve been reading lots of posts regarding tv screen going black before turning off then back on. The tv is 3 months out of warranty and is a Samsung AU 8000 50. We have unplugged it, tried a new HDMI lead and re set it countless times now. To say we are fed up is a massive understatement. What will fix this and how much is it going to cost? This is obviously a common fault. Thanks. Mick
