My AF9 is just over 6 months old, and a couple of days ago, it asked me whether it could perform a panel refresh autimatically. I allowed it to. After that, a line appears on the TV, at the edge of a shadow, which covers 3/4th of the screen. I have performed a manual panel refresh again, but, this did nothing to improve the situation. Any ideas? I will call Sony re guarantee next week, I suspect it might just be a faulty OLED panel, but I do hope that it is a quick fix solution, rather than the TV being taken away and me not being able to enjoy it.Shadow and line on screen
