i had only just bought this tv and 3 weeks into having it there seemed to be a white and black line through the tv. phoned samsung but they tried to tell me it was an impact and wouldnt send no one out to look at it.I havent touched the tv at all so clearly a fault with the tv. AWFUL customer service. Have logged a complaint as they wasnt helpful at all. kept getting messed around by different representatives. Have spent so much money on this tv and im very unhappy and dissapointed.will not be buying from samsung again. I looked on line and there were quite a few people with the same issue with this tv. DONT buy from samsung.
