“Well. It sounded good at the time!” – I bet she was thinking. Usual corrosion on SSD and main board. Not much of a problem. We’ve done this before. But look at that ribbon cable for the 2-MIC Connector! (Yes, microphones.) The trace for the 3.3 volt rail was badly corroded. DeOxID and fiberglas brush left no copper remaining on that trace on the right. Fascinating.
I got a fix for this!
A dab’ll do ya. First, I scrape back some of the ribbon cable’s black plastic insulation, exposing good copper trace. Bridge across missing trace gap area.
Here’s the wet silver paint. Applied 110C for 10 minutes. Let set for a few hours. Clean up a little. This Macbook needs much more diagnostics and work to make it right again. Will update as progress is made. This one’s pickin’ on me!
