I remember when researching my purchase a few of you on here brought the 50, 58 and 63 inch 7000 series models, I am having it seems a common problem with these TV's. When viewing light colours and whites especially ads etc I get a noticeable purple pink discoloration through the top region of the screen. Just wondering if any of you out there are having the same problem/issue? After some googling it seems to be fairly common, however the only results I get are from Aussie or beyond. Secondly it is around 15 months old what should I do? Call Samsung go back to Harvey Norman?
