Samsung S7 Screen Issue

Feb 1, 2019
So I dropped my phone and obviously it hit the ground. So I pick it up Check if its scratched and turned it on. There way no damage visible untill I turned it on. The screen has now a some white stripes its dark as hell and there is a green tint and sometimes its just goes black. Is there an easy fix to this or do I have to take it to repair?[
