I am beginning to think this view is correct. I do see a little corrosion
on the mobo in an area roughly three inches around the AC connector. Just
dullness and little flecks of white on places that on other areas of the
mobo are bright and shiny. Some of these parts, ICs and resistors, are
minute, so that even a little corrosion might short the connections.
Cleaning the mobo won't help, because the real problems are probably
hidden, some possibly inside an IC or in the subterranean layers of the
mobo itself.

I did get the two pairs of red and black wires unsoldered (why didn't Apple
use connectors here???) but got stuck at the ribbon cables.
