Purchased a 65 inch samsung curved tv less than 3 years ago. It developed a tear drop shaped white spot upper right hand corner.I looked on several samsung websites and found this is a very common problem. In fact i found a picture of another tv with the exact same spot in the exact same location. I payed about 3700 dollars for this thing on amazon. Samsund knows they have a defective product and refuse to aknowledge it and refuse to recall these tvs. The thing is now a boat anchor as it is off warranty. Do not buy a samsung tv they do not stand behind their products.
