Same problem as everyone else. Owned the tv for more than three years and started having deactivating issues on netflix app. I can tell you that the problem is samsung and not netflix. I have 5 sony blu-ray players including a playstation which I use netflix on and I never have any problems opening netflix. Samsung might want you to get a new tv? If I needed to buy one it won't be a samsung for sure. So my solution was to connect one blu-ray player to the "smart" tv (not anymore!) via hdmi and problem solved. I get a better definition with the blu-ray player by the way. You can still use the other apps with the samsung smart tv.
