Hello,
I have a buddy who had a cup of iced tea spill on their PS5 controller. It was sticky/malfunctioning so I told them I could attempt to clean it with isopropyl and see if I could get it working again. When I did an initial test, the buttons seemed fine. I disassembled, cleaned, waited a few days before reassembling the controller. I put it back together and the face buttons/d-pad wouldn’t work. I assumed I had somehow damaged the flex cable. I replaced that just recently, the buttons still are not working.
I attempted to swap the motherboard into a midnight black dualsense casing/parts, the face buttons do not work. Once I put the black controller back together with it’s original parts, it functions again. I know they are different board revisions, but the flex cable connector looks the same/the replacement flex cable for the white dualsense is not functioning either.
This leads me to believe it’s a board problem, maybe a shorted trace or something, but I cannot figure out where to begin. I’m not sure where I should be testing/examining on the board.
