Since it crossed borders you may be shot down as such things can be region locked.
Only Netflix and the maker can fix it and even then they may walk since it was not sold in your market.
I have recently purchased the above Panasonic viera-TX-40as640e.It is the European model imported from France and adapted for the UK market.
I have checked all app headings in apps market, on home screen, however I cannot see an option to select Netflix, has anyone any ideas. Should this TV, have the capabilities or not? If yes how do I down load it for use?
