Straight white and pink lines on screen after fall

Hello everyone,

today my screen fell down on the floor, the screen didn’t crack but it got 2 straight thin lines (white and pink).

the 3D Touch and the touch it self works fine though.

I thought maybe open the phone and check the screen connectors to the motherboard, but thought to ask here before doing it.

I don’t want to waste 300-400$ for a new screen, and also this screen may be not genuine (3D touch won’t work as supposed to and screen won’t be high quality).

What do you say?
