I have no clue where to start, I got lucky by having a few donor boards for my last jobs and was able to just swap out clearly damaged parts. Where should I start for this one?
kind regards

I can say that most of the water damage is over by J6700 and J3500, or at least I hope I am correctly telling you. C3577 looked really terrible so I pulled that. I don't think I am supposed to ask this but I have tried finding it online about how to measure PP3V42_G3H and PPBUS_G3H but I am not sure. If I measure PP3V42_G3H at L6995 then it is 3.478. If I can measure ppbus_g3h on F9700 then it is 12.26.
I hope this is right info I am giving you. This is my first real try to fix a board.
