The reason why it's not working is because you hung your TV upside down. J/KHello, I just recieved my Samsung 65" JS9000 SUHD. Had it mounted in my bedroom. Purchased My Passport Cinema drive. Got Exodus and Maze Runner HDR free ! This tv is awsome like the movie theater. One problem though. The youtube app doesn't work, won't load videos. Got the TV and 7500 Soundbar for $4K
Try restarting or resetting the smart hub. As always, please remember to write down the settings you have for your picture before resetting anything.
