Sometimes you cant. Although, sometimes all you have to do is take the battery out and let it sit for a little bit. If that doesnt work then it probable is broken. If its water damaged but the phone and the battery seperatly in a bag of rice.
get a new phone
only if you have insurence. if you dont then no knew phone.
The screen itself or the phone itself are the easiest parts to break. Just dropping the phone can damage the screen or the outside of the phone and a cracked screen is hard to fix.
take it to the hospital.

if the screen is black you cant fix it is an internal crack that spread to the external part of the phone.
Turn it off then turn it back on
Maybe 90% if the original price
buy a new phone or ask someone to fix it or turn on the brightness
A reputable shop is a place where they fix the screen of your ipod, phone, etc.
