Got a cheap partially working gbc. Thought I could give it a try to fix it. Turns out the pads/contacts on the A button were already ripped. Any idea how to fix it? Or is it a goner? Thank you.
do you mind pointing out the traces in the picture? I don't understand what I should do with them. so I just have to solder 4 wires on the 4 broken pads on the A button? If I see it correctly, do they all merge into 1 trace? thank you.I can see where the traces wander off to on that image. Or if you mean what shape do I make them then if the negative of the now missing thing is not enough then the b button (which looks like it might want a cleanup as well) looks to be the same size.
P10 is just a test pad. But the via for the a button is right next to it and emerges again somewhere above the U10BE silkscreen marking. If you have continuity between the button pad and those vias, it could be a problem with the CPU CGB, where it directly connects to pin 125 if I'm not mistaken.Any conclusion to this? I have a gbc will all buttons working except the a button, it seems. Only real physical damage seems to be the p10 point so wondering if it’s not a test point and actually important for the pads to provide input. All cleaned multiple times so it’s not residue on the pads
