Posted about this earlier, but I've opened up the computer for a look inside to see what sort of repairs i'm looking at. As you can see on the attached photo right there in the middle there looks like there is some corrosion on the logic board (what looks like some salt and some copper-hued coloration). I was in at the Apple store and they told me it looks like water damage or some other corrosion (if its water, then i'm a bit perplexed, as i have no recollection on water damage). I'm out of warranty. I suspect i can replace the logic board and all should be well, but i'm wondering if anyone specifically recognizes that sort of damage as something beyond repair? If its salvageable, i've got a quote from a local guy who can do it for $330 with one year warranty on the whole computer. Is that a decent price? Thanks for any help.
