Why did the man turn on the TV ?
Why the man turned on the TV ?
Sometimes, I guess, I hear or see these two constructions, so what is the difference ? Does the second is more often in sopken language ? And do both of them are formal ?
Thank you

When asking questions with interrogatory words (Who, What, When, Where, Why, How), we use a helper verb with the bare infinitive. The plain tensed verb is not used.
Why did he turn on the TV?
Why he turned on the TV? ungrammatical
Why do you go into the city?
Why you go into the city? ungrammatical
We can also use the participle:
Why was the man turning on the TV?
Why are you going into the city?
P.S. Hundreds of years ago, the situation was different, and an English speaker could ask a question without a helper verb and using a different word order:
Why go you into the city? archaic
What said he about their misfortune? archaic
Why did the man turn on the TV?
Why the man turned on the TV.
The first sentence is a direct question. It's complete and correct grammatically.
The second sentence is part of an indirect question. As a complete indirect question, you can, for example, say:
I wonder why the man turned on the TV.
Could you tell me why the man turned the TV on?
I want to know why the man turned on the TV.
