Got a raiden board that I was told was completely dead and covered in coke.
When I tested it, I found no video, but if I tapped on the HB-41 custom responsible for sound, I’d periodically get some game sounds. Touched up a few questionable solder points under the board and audio came back. Got a Caius repro just in case.
For the video, I quickly tested the outputs at the jamma edge and found no signal at all. I should have noticed, but the UEC-52 custom was complexly ripped off the board. Cleaned the pin remnants out, added some pin header, and one of Caius repro. Brought the board right back to life.
Pulled all of the socketed chips, daughter board, and UEC-52 to clean. Spent about 30 minutes with a toothbrush, hot water, and dawn dish soap. A quick rinse off in the sink and some hair dryer action to get as much water off as possible. A day under the Texas sun dried it the rest of the way.
Nice to have a repair done on a board I get to keep for a change!
