"After upgrading your TV, it is necessary to perform a "cold start". This means that, after the TV is running again (after the update), shut down the TV, wait 1 minute (till all components are shut down), and unplug the TV from the mains (pull power cord) for 2 minutes before starting again. After this I advise to do a complete reinstallation of the TV as this is a new branch."
