I recently got my first original cabinet: a 2P Astro City. I bought it from a FB seller in California. I had it in my garage, hooked up to a few different JAMMA boards, and everything seemed fine. While cleaning out the cabinet with a shop vac and air compressor, I smelled the distinct smell of burning electronics, but didn’t see any smoke or fire. Now, the monitor doesn’t turn on. No static crackle or blank raster image. Audio works, and I also verified +5V from the PSU. I discharged and removed the chasis from the machine. Where do I start with the troubleshooting process?
