I've also ran into this problem as of Sunday 2/09/14 around 4:30th PST I've called netflix they had told me it's Samsungs end I called Samsung and they told me it was Netflix end so I called netflix back they ran me through the complete troubleshooting to tell me the same thing they are communicating with Samsung to resolve this issue...For being a standard TV quality is great as for it being a Smart TV it's not as great as I thought it would be and it's the second one I've gotten. I had to warranty my first 40inch smart TV by Samsung due to it crashing when it was trying to search for the Wifi connection.
