I bought this T.V. 1 and half year ago. And just after 1 year quality of display screen goes slightly down. There are 2 lines appeared at the bottom, after sometime lower display gone blueish and red. I reported this at customer service, they said you need to change the panel of display screen, which costs about 20 to 25000.
So don;t buy this product, although the picture and sound quality is very good, but with such big issues in a very short period, its a total waste of money.
The customer service is also very bad by Samsung.
