Wi-Fi, Bluetooth, sound and microphone not working, what's wrong?

Hello, I've a problem with my iPhone.

When I try to enable Wi-Fi, the write appears grey and says "No Wi-Fi" (PICTURE NR.1)

and it's impossible for me tap it to enter inside the menu.

The same for Bluetooth, the write appears grey and says "Unavailable". (PICTURE NR. 2)

Inside the menu "Settings-General-About" I have no informations about Bluetooth and Wi-Fi (empty fields).

(PICTURE NR. 3)

Are Wi-Fi and Bluetooth manged by communication board?

Are microphone, audio and vibration managed by communication board too?

I know that I'll have to change it cause a broken connector (PICTURES NR. 4)

Thanks so much.
