Minor grammar Nazi point (since you mention you are Italian, and might be interested) - "turn on" is either "sexually attracted to" or "suddenly attack", depending on the context. i.e. "She turned me on, the smell of cigarettes is not a turn-on for me, the dog suddenly turned on me and started biting". I've no idea why ...

You mean "turned to".

Then why does "...turned on a television" work?

Because it's a phrasal verb with multiple meanings: http://www.macmillandictionary.com/dictionary/american/turn-...

Right. The OP's comment made it seem like there are only two definitions of that phrase(neither of which applied to my example):

"turn on" is either "sexually attracted to" or "suddenly attack"

[wisty]

Yeah, I couldn't think of any other's. Phrasal verbs are tricky like that.

I've heard people say "he turned me on to the idea of..." without it having a sexual context.

Oh, the English language...

Not a grammar issue, it's a colloquialism. I used this phrase all the time.

"My old roommate really turned me on to the Wire. What a great show."
