I can't reset my new Hisense Smart TV to factory default?

I really need help. So I got a new TV and it's a Hisense Smart TV and as I was setting it up i can across this choice: Auto Scan, Manual Scan, or skip. Well I clicked on Auto Scan. Now I have no channels. I read everything on the paper again even the parts I skipped and I read that I should had skipped scan. Now I'm trying to reset my TV all over again but when I clicked on the Reset to Factory Default it says "Are you sure" and I press OK but it just goes back to the menu and nothing happens. Please tell me what I can do
