The thing is I couldn't identify which solder joint was bad. Usually they look gray instead of shiny or they have a kind of crystalline look that isn't right. But once you guided me to which to it, I reflowed that joint and everything that was attached to it.
I picked that color out of about a hundred sample chips over a year ago. I don't know the manufacturer or the color. I use a guy in West Chester here in Pennsylvania named Dan James. He powder coats part time. He calls his powder coating business Full Spectrum. And his rates are very reasonable for hobbyists. I think the charge for this plate and the red plate for my friend's Moreplay that I built plus the black transformer bell housings was $60 altogether.
