Hi, I purchased this 75 inch Samsung TV less than two months ago. Brought it to the store I purchased it from showed them photos of defect and fault and they confirmed they could see it. I contacted Samsung and was told by two people they could not see the squares and lines on the TV. The squares are blatantly obvious on the telly, there is a clear fault. All trouble shooting options have been tried and failed.
Squares are clearly visible in these photos.
