I have this issue too it’s from the board being dropped a lot / age. I bought an extra used controller and some 3d printed replacement shoulders and I’ve been able to fix them pretty well. Unfortunately there is no way to fix the board I wasn’t able to discern any kind of issue with the parts but I don’t have voltage schematic to figure out what might have went bad I suspect a capacitor or something. I still use them every day though they are great. I hate the new steam interface though cause they dropped a lot of advanced features
Reminds me of Republicans questioning Ketanji Brown literally the only thing they asked about her was about how hard she was on pedophiles. The level of projection was palpable. Basically confirmed that all Republicans are predators.
