Hi, this is a small circuit board from inside a Pioneer S-Z460 speaker. As you can see in the picture, one of the wires has been ripped off. How can I resolder it without the copper solder area in place? I've tested the two other points at the red marking with the small copper sticking out from underneath the green paint, and it's a connection. Do you think those three are just the same? I'm new at this so please explain simple, thanks!
