how bad was the cap goo leakage?

I'm thinking yours is pretty much doing the same thing as insaneboys.

there are some data lines that go to the SWIM and they get messed from rotted via due to cap goo.

could you do me a favor, check out the schematics and use your meter and figure out what connections are toast?

then post your results? i think your fix will help many.
