A:Answer I cant answer this question, only I can say that this TV is very good, the picture is sharp, works perfectly, comes with 4 years warranty on parts and labor, unlike other TV. I would recommend to purchase it.
But I would never recommend to purchase TV's from BEST BUY IN SIMI VALLEY. When comes to a problem with TV(after only 10 days of purchasing) the sales people including the manager would give you such a hard time, give you all kind of excuses not to change a TV. Another word STAY AWAY FROM BEST BUY IN SIMI VALLEY....
