Normally, you would select Home mode during inital set-up or "Plug and Play". On my set, you can re-select this by pressing volume then holding the Enter key for 5 seconds - check your user guide in case it's different.
I just bought a UN46B6000 aka series 6 46" LED t.v. and i want to know that how to turn the store demo mode off on my T.V. because it really gets to my nerves when i try to watch a movie.
p.s. can you help as soon as possible please?
