try performing a reset of the Netflix app it self... push the buttons on your remote: up, up, down, down, left, right, left, right, up, up, up, up the Netflix app will need to be active while doing this combo. another thing you might try is registering/log in to the Samsung account on you tv in the smart hub. also when you have the Netflix app highlighted, you might try pressing tool and then select reinstall you could also reset the tv back to factory and then reupgrade the firmware and such. on our network, there can be no other traffic or for some reason the firmware upgrade get corrupted partially. we have had to redo a firmware upgrade more than once before.
