Fix a bad PCB on my SE FightStick?

Hey guys,

A long time ago, I purchased a mad catz SE fight stick. A few months in and I noticed that the X button (it’s a ps3), or lower left button wouldn’t work. It actually triggered the turbo light when I pressed it. During this time, the other buttons would work just fine. It will work after plugging it in and out a few times, or trying to turn turbo on/off. It’s random.

Anyways, I was wondering if anyone knew of a way to fix this? I’ve since bought a TE stick and the SE stick has been in the closet for awhile, but I just dusted it off (to sell), but was hoping i could fix this somehow.
