You can try Samsung and other warranty again but the years means OOW and can upset folk.
My bet is a bruise of the LCD which means a new panel. Estimates have always been more than a new set.
MY samsung smart LED TV 5500 model 46" purchased in oct 2014 is showing cloudy gray spot visible when the screen is white. SSC club response is not satisfactory. Pl. Suggest what to do?
