Broken screen or wire problem

3 year old MacBook Pro 2019 , A2159. I have attached pictures of its different stage. At first it was a vertical strip of black screen at one stop but has gotten progressively worse. As apple normally recommend to change the whole screen which is expensive. what could be causing this.

TLDR ; screen worked only on acute angel , had a vertical black strip but got worse. apple technician says its broken screen. need second opinion
