Broken and blank screen after the drop

Hi. I dropped the 6s Plus and the screen is shattered and went blank when I turn on the phone. I see totally dark screen. I opened the phone and checked for any dislodge connector and I found none. All the connectors look intact. The good news is that when I connected to iTunes it sees my phone and it allows me to backup, restore, update, and whatever. Is it safe and 100% sure to say that the only problem is the screen and not the logic board? I really don't want to buy a new screen and to find out there is also any issue with the logic board. Any advice would be appreciated.

Thank. This is my first post in here.

Thank Clayton. I did shine a flash light on the screen and can not see a home screen and completely blank. I guest that is good news. You mentioned about the backlight. How do you fix the backlight? Is it a backlight chip on the logic board that need to be replaced? I hope that is not the case here. I don't want to do microsoldering or fiddling with the logic board. Thank you, sir!
