My 18 month old 43UJ635V-ZF has very annoying purple tinting down the right hand side and bottom left hand corner. I'm hearing this is a common problem with Tv's like this and see many Forums on Samsung about it. There was no physical damage done to the TV And it just started happening. Does anyone know why this happening and is there any resolving this? Amazed by the amount of people having this problem and wondering what the best course of action is? Time to scrap it or try and repair?
