1. Be sure the date and time is correct on the Tv.
2. if 1 fails, use the Google DNS of 188.8.131.52 and 184.108.40.206
3. Check if there is newer firmware for the TV.
4. If all this fails, call Netflix.
I have an un55es7150 i did all the updates for the TV as well as Netflix, and it works great for a few weeks. Now every time I try to go on, it says "We're having trouble playing these titles for you right now. Please try again later or select a different title." I have tried different titles, other movies, deactivating Netflix and reactivating again but the problem persist. It took so long to load and always ended with the same error. Please help
