Bought a new television QN85 - 75" in April.  TV flickering, had shadows, periodically has no picture but has sound.  First visit, they repair, does it again; 2nd visit, they repair, now the TV picture never works; Samsung tech asked our local tech to have me try some things which I did no luck.  They now want to come out a third time.  At what point do they just put a new TV in!  I feel like throwing this in the trash and just going out and getting a Sony.
