Hello!
I just bought 46PFl5507K and i wonder if you know how to solve this problem: if i have TV connected via wifi, i can control it with ipad and all works. but when i connect tv on wired, ipad app DOES see my TV, connects to it, TV also HAS internet access, but i can't control nothing. OK, for TV guide i suspect that my country (Slovenia) doesn't transmit correct format, because i don't get guide code with yellow button but just help pages. But i would really like to get remote working and have tv connected to wired because streaming is faster this way.
And, yes, i do have uPnP in router enabled.
