Won't Power On - Logic Board?

crwdns2934249:0crwdne2934249:0:

My late 2010 Macbook Air has liquid damage.  For about a year it worked fine, then it stopped working.  I took it to the Apple store and they replaced the I/O board.  A few months after that, it stopped working again.  If I plug in the power adapter, the LED doesn't light up.

I took it too the Apple store, and they said they couldn't get it to power on directly from the logic board, and they said it was a possible logic board issue.

I have a new Air, but I want to fix this one.  I have a sneaking suspicion that the Apple store didn't fully diagnose the issue.  The fact that I see no power going to the battery through the IO board (LED not lighting) makes me think it might be the I/O board they replaced which is not working properly.  I have no idea how the power flows through the laptop however, and I'm aware it could be any piece in the chain.  I've taken the whole thing apart and I don't see corrosion, and the only evidence of a spill is near the I/O board and behind the fan, (when I pull it out).  The logic board looks clean.

Does anyone know how I can diagnose if the issue is the logic board or the I/O board, or even the Keyboard or Battery?  I can purchase both the IO board and Logic Board and test, but it seems an expensive proposition.
