We purchased the Sharp – 70" Class Smart AQUOS 120Hz LED 4K Ultra HDTV With Wi-Fi from Brandsmart this past Friday. They unboxed it in the store and my husband checked it for scratches and dents and signed off on it. When we got home we noticed very faint horizontal line across the top screen. We boxed it again and took it back to the store for an exchange. When they plugged it in it had a large black mark on the screen as well. The TV was handled with care and you can tell it was never dropped because of the frame. Brandsmart does not want to exchange it and they are telling us that we are stuck with a broken TV. We have been saving money for quite a long time to purchase this TV and we are beyond disappointed and frustrated at what is happening.
