The basic solution of toggling the aurtorun options did not work for me so I factory reset the tv. After that the Samsung tv service continued to start at startup but now the app for it, which I had previously removed, was showing again on the Home Screen. I went to remove it (up, up, remove) which produced a screen with not only remove but also the additional option “disable”. Disabling removed the app from the Home Screen and stopped it starting when the tv starts. I figure I had disabled this when I originally bought the tv and the latest update has confused things. Basically if you have previously disabled the app you need to either factory reset and disable again as I did today, or possibly simply re-add it to Home (go left to “sources”, up and add back) and then disable again. Hope this helps somebody.
