I think that in order to find out exactly what happened and what needs to be replaced, if anything, you need to clean the logic board. So, I would go ahead and clean the board with my favorite. Isopropyl alcohol, because it does help to replace water, and to scrub the board with a soft brush, in the past I have used a soft toothbrush. Let the board dry of thoroughly and then you can take a closer look at it. That is where a good magnifier comes in handy as well. Once it is clean it might also be easier to determines if it is leakage or water corrosion. From your pic, I am leaning toward corrosion. At least once you have it cleaned and assembled it might also be easier to determine if you have an error and you will have an idea where the error is (corroded parts) that you then can think about replacing. So to recap, clean, assemble, trouble shoot, repair (if necessary. as for the silver paste, why should there be thermal paste under the ribbon cable. I do not think it should get hot enough to require thermal paste, but I am kind of stumped on that one :-) but those are just my two cents. Good Luck to you.
