Being that this machine suffered water damage I would start by cleaning the ribbon cable and connector on thr cable and logic board end first. That failing, I would say that the tiny lighting tubes might be damaged and that can only be fixed be replacing the topcase. It's not that Apple technicians dont know anything, it's just that they push for the most expensive repair possible. Hence the reason they almost always say everything is a "logic board issue". That was a good find for $400, even if you have to replace the keyboard, you are still good. Good Luck.
