after some digging i found this dudes answer to the problem
Quite easy, just go into the Service Menu (TV off, then press Info, Menu, Mute, Power on), go to Options menu, and voila - there you can enable InfoLive.
i recently became an owner of LN40A756 and along with the other wiselink troubles i have been experiencing it seems that i have one more at hand
when browsing through the menus i do not see InfoLive at all as an available option.
i have successfully connected the TV though my router (test is OK)
i have set the region and all other things to England etc,
but still the menu does not appear.
i have searched through the web but no answer seems to be available.
any ideas and suggestions would be greatly appreciated
