A heads up - my Samsung Frame 65" has failed after 23 months. Samsung have been no help whatsoever, only repeatedly stating it's out of warranty and telling me how much they value my custom :-). I've tried phone & twitter, exact same response from both - tough luck.
You can see the issue below, dark bands on either side (or a light band in the middle). It's a clear manufacturing defect, a local supplier has quoted over £500 for a repair. So, it's cost me the princely sum of nearly £100 a month to own this TV.
As the owner of 3 Samsung screens, and generally a regular (far too regular!) upgrader, I won't be purchasing a Samsung screen ever again. What a shame, as the functionality of their products is generally excellent.
