Hey all, I'm trying to hopefully restore an old gameboy I got and there's bad corrosion on the board. I've uploaded the pics of it front and back and am wondering on the one if the battery positive (in red) connects directly to the power converter board trace I highlighted? (in yellow) if so that's Mt issue as it is the only spot not having conductivity I've found. Oddly the ground pin has connectivity and it's by far the worst. Any help is greatly appreciated!
