Hyundai Led Tv — tv is not working now

Actually we brought hyundai led tv hy3221hh2 on 27/1/16 with the warranty of 5 years but now tv is not working but the company simply telling that it was our fault. The problem is white spaches coming on the screen. Our dealer is simply telling that he sent the photo to the company so that company is telling that is customer fault but actually we doesn't did anything. We need the proper response from the customer care and also we need proper solution. The product id is[protected].
