@ranger55: Please can you confirm the model number of the TV, located on the sticker on the back of the device, or in Settings > Support > About this TV?
In the meantime, please can you let me know if you're getting any error messages or notifications when you attempt to sign in to your Samsung account?

@ranger55: Thank you for that. Please be aware that I have removed the photo in your previous post, as it contained the serial number of the TV. If you're getting error 189 when attempting to sign in the Samsung account on your UE55MU7000, then this indicates that the TV is unable to connect to our servers. This could be a temporary authentication issue, or your internet connection may be too slow. Focussing on the latter, please ensure that your TV is connected to a stable Wi-Fi router by heading to Settings > General > Network > Network Status. I also recommend unplugging your router at the wall for 30 seconds, then plugging it back in and allowing time for the reset process to complete. Let me know how you get on.
