I can't give an authoritative answer on that, but the European models all begin UE. I suspect they have a different main board. I saw recently (in here?) a post from someone (who know someone) who had a TV converted from Middle-East to European model (or it could have been the other way around!) That seemed to have taken some kind of service installation.
I am right now working i China
I would like to buy a TV here, the top candidate is Samsungs LED model UA55B7000WF
I am a bit worried aboute the different systems around the world, you know PAL, NTSC and so on
My quistion is simply this: will a TV and especial the Samsung UA55B7000WF also work when I return to western Europe?
