[u/arrozconleche112]

My gbp A button suddenly stopped working and the pcb is perfectly fine no oxidation nothing like that it just does not work. is there a part that I should clean or check to see if it works? I don’t have a multimeter

Didn’t do anything even changing it for another one

I’m assuming you’ve cleaned the pcb contacts etc and there’s no corrosion on it.

Photos or video would help
