Good news. I've got it working again. The boards are laid out on my workbench and I'm not done with it yet, but it's getting there. I replaced all but one of the electrolytic caps. I needed a 22uF 35v but I only had some 16v and 25v. Got a few ordered, but in the mean time, it's working with that old cap.

I replaced a dead LED and the new one is WAY brighter than the rest. I'll replace them all while I'm at it. Good thing I got a bag of 100!
