I think The Real Alexandre has understood.  Probably the best translation is

"Voce nunca assiste televisao pela manha?"

Nao estamos perguntando se alguem esta acostumado a assisti-la todos os dias ou muitas vezes.  Basta que assista apenas uma vez nos ultimos 10 anos para ele responder com "sim".

Do you ever watch TV in the morning?

Yes, I watched in once a long time ago, but I never watched it again.

Yes, maybe I watch it once a month or once a week.

Yes, I watch it every morning and every afternoon too.

 No, I have never watched it in the morning.  Never.

By the way, the question could also be worded "Have you ever watched TV in the morning?"
