After some more drilling and cleaning, the s/c disappeared. I connected some signal paths on the PCB by making some educated and some completely random guesses, and I used the thermal camera again to check that at least the last ASIC still worked. And it did!

After more drilling, the mf still wouldn't go away, so I took another video. Btw, drilling a PCB is no fun. I was essentially burning the material away and subsequently inhaling it instead of drilling it. It seemed to be a four-layer PCB.

However, the s/c wouldn't go away, so it was time to take out my new thermal camera. I connected the board to a regulated power supply, set the voltage to 12V, and limited the current to 10A. Here's what I got.
