For some unknown reason Samsung on most models doesn't have an option to turn that off.
You have choices to make here. Call it in and confirm then decide if the set is going back as its design doesn't work for you.
First off, aerials do not work in our rural area so I have just bought a Samsung smart TV just for use with Netflix. I have set it up but on every turn on it gives me the error "no stored channels found please run auto tuning". I have run auto tuning (and it didn't find anything because I have no input.)
Whenever I use the smart hub I get the same error behind that too (are you meant to have a nice picture like on the box?)
Netflix itself works fine and the picture is fantastic but I would like to tidy up the intro and background. Does anyone know what I am doing wrong?
