Hello, I just got this TV UE64F8000SLXXC few weeks ago and i still can't manage to get Smart Hub applications to work. whenever i try to open any application Except for the web browser, I end up with a black screen that doesn't exit unless i click the Smart Hub button on the remote control. I already tried to reset the TV to factory default and change the country but no luck. Does anyone have any idea what maybe the problem and how can i solve it. Thanks in advance for your help.
The solution is to factory reset the TV from the Service Menu which you can access by hitting INFO MENU MUTE POWER on the remote control while the TV is in standby. you can read more about service Menu on samygo forums just google it.
