The problem with the PCB has only occurred perhaps one or twice a year when it rains heavily and often with high winds. The percent humidity is probably 90 percent or higher.
Some my previous pics for some reason wouldn't upload pics with the green stuff from one of the chips. which I cleaned the best I could with electrical contact clean and a toothbrush.
I was able upload most of the pics to another gallery which does shows the green stuff on the pins of one of chips. (after it was cleaned)
