I think I'm having the same problem as Tom S. with by B6P, though after factory reset my TV would respond to the magic remote for a brief period...some of the time. After many restarts, I finally got through setup, and now I get the "Bluetooth service needs to be initialized." message every time I push the wheel/select button, so TV functionality seems severely limited. I've ordered, and will try using, the AKB73975702 remote, and will post whether that worked for me too.
UPDATE: After some time (maybe six restarts), a message pops up saying that the magic remote has paired...and the TV seems to be back to full functionality for now. I'm sorry that the resolution seems so mysterious (not sure why it paired then and not any of the many previous attempts).
