I ended up with a pinball machine over the weekend that worked ok. It had a few gremlins that needed to be evicted but I have yet to own a machine that wasn't a little rough around the edges when I first invited it into my collection. I ripped the play field apart cleaned with Q-tips and a toothbrush every nook, put new rubbers on, installed new LED bulbs, and fired her up. I still had lights out so I pop open the top box and to my horror find the culprit.
A long time ago in an arcade far, far away... The 100uf cap on the driver board blew and spewed its nasty filling all over the driver board. Judging from the level of corrosion this probably happened years ago and was never addressed. It burned a hole through the board itself trashed a resister, a smaller cap, and three trace leads.
I can replace the caps and resister, retrace the board, and fix the transistors that were definatly destroyed. That is no problem. But there is a lot of corrosion here and there on the board which is most certainly going to cause me trouble in the future. Any words of wisdom on how to get the corrosion under control once the board is correctly repaired?
Thanks!
