My HRAP 3 seems to be having some issues

Recently, I’ve noticed that sometimes when I do a double QCF motion with my HRAP 3 in the SSFIV challenge mode the start menu will decide to pop up. I know for a fact that I’m not hitting the start button accidentally.

Similarly, sometimes when I do a double QCF motion in an online match, my character will freeze completely for about half a second as if I had performed no inputs.

Clearly, I’m having some issue with my Start button but I have no idea what it could be. Anyone have an idea?

Open it up. It sounds like the wires have gone loose.

How would I fix these loose wires? Am I going to have to buy a new stick?

It can be fixed but, you have to open it up to do it.

I’ve opened it up before to add Sanwa buttons, so that’s not a problem. I’m just wondering what it will take to fix the wiring once I’ve opened it up.
