Charge Cord & Display Cord not working on Mac Display

Heey Apple world.

I have a slightly older Cinema Display I bought a few years ago, and a last generation 15" Mac Pro (no scroll bar). The charger on the Display is from 2 generations ago, so I have the little silver adapter for it to magnetically snap onto the charge port of my Mac.

Recently the cord has started acting up so it only works if I mess with it for a few minutes. Both the charging capabilities and the display is affected. Now I can only hear the audio on my display, and not actually see anything when it's plugged into my computer, and it takes a good few minutes to get it to charge.

Is there a way to replace the cord, or am I doomed with a faulty display??
