Trying to FIX: Xbox One Controller A,X & Y Buttons NOT Working

Hi, this 'trying to fix' video shows me attempting to repair a Xbox One controller with faulty buttons (A, X &Y). Remember that this is just for entertainment and I am not an expert in these repairs. The processes in the video may not be the best way, the correct way or the safest way to fix these things. I do love fault finding and trying to fix broken things so I hope that comes across in this 'Trying to FIX' series. Many thanks, Vince.
