Hori V3 PS3 stick problem


I got the Hori V3 stick a few months ago when I started really getting into the fighting game scene. However recently the Triangle button on it has become hyper-sensitive. Touching the button(not pressing), moving the pad and sometimes hitting one of the other buttons quite frequently causes an input. As you can imagine this makes fighting games difficult when you start randomly hitting Medium in the middle of a combo. If anyone has any idea how to repair this I’m all ears. I’ve tried taking it apart and using canned air to possibly move something that got caught in it. Thanks for whatever help you can give.
