I purchased a QN90D 75inch TV this weekend. I used it Saturday, Sunday, Monday with no issue. Today (Wednesday )I turned it on and only the middle of the TV was bright. No settings brought it back to normal but I did cut power to it and after turning it back on, it's working fine. Should I be worried, is this a fluke? I have 2 year warranty on it. I came from a Q70R that has never had any issues at all.
