There's continuity between CN12, IC1, and from IC1 to IC2. However IC1 does sort of look like there's some corrosion or some damage on its pins. The white text on it has faded off while all the others exist there so it definitely stands out. I don't know if that could mean it's overheated, but it also gets the proper 5v to its power.
I can go ahead and try replacing it and IC2 as long as I can manage to find them on mouser. Is there an easy way to "force" the switches with a jumper?
