Inverter Cable conncting to motherboard difficulty?

Howdy! I asked a question a couple weeks ago about a faulty backlight display. So, after a couple weeks, and a couple inverter boards and cables I think the problem has been identified. After installing a second new inverter board and cable, I decided to turn on my MacBook while it was halfway apart, to further troubleshoot why my display was not being lit up. When I wiggle the inverter cable around, it will flicker more and more, and at certain angles, it actually stays on! So, my question is, can I replace the tiny part that the cable plugs into on the motherboard? The little plug in that is, or would I have to purchase a whole new mother board?!

Thank in advanced!
