Anyone have any tips for repairing or desoldering corroded solder? I've tried applying fresh solder but not all points would take it.
Also, I'm thinking the brown line across the bottom is supposed to be a connection between all of them for ground. I think its corroded to not work as well anymore. Does that look/sound right to people? In the second image, it's the side with a single wire plugged in.
@demofox Ideally you'd desolder everything (flux and solder wick), clean it, then see what the state of the PCB is. That does indeed look like a trace that runs the whole way across on the bottom. If you're messing around it might also be worth just replacing the push buttons since they should be easy to get and they seem to have corroded legs also.
