I fired up my warehouse condition Gottlieb Arena for the first time yesterday and it looks like it has some issues with its CPU, at a minimum. While some of the lamps come on, as does the backbox neon, there is nothing on the displays, no lamp cycles or any audio. All of the fuses have continuity and the voltage coming off all of the components of the aux. power board are right in line. But I couldn't find any test points on the CPU board, and had no idea where to start there. I unplugged and re-plugged all harnesses in the backbox, and that didn't seem to make a difference.
Any suggestions on what I might try next?
