MacBook Pro replacing LVDS cable after stabbing it.

My dad was attempting to replace some of the plastic feet on the computer when he accidentally stabbed with a steak knife the inside of the computer hitting the lvds cable or the port that it connects to, he is uncertain what it hit.

I am uncertain that if I purchase a new lvds cable and replace it, it will not fix the display because the damaged part is the connector and not the cable and I will be out 35$. The lvds cable has been removed to see if there is any damage underneath since it got cut as well. Stab mark is visible in images

My question is whether I should go forward and purchase a replacement part (cable or something else) or give in and buy a secondhand mac.

Photos of what screen looks like, unwanted colors are somewhat flickering.

Images were best I could take of the connector and cable, please ask if you need anymore information or photos, I would really like to know the answer to this
