Leo ran a small board-repair shop in Queens. No certifications, no storefront. Just a microscope, a Hakko soldering station, and an oscilloscope that had seen the Clinton administration. His specialty was the "no-power" fault. Most techs would replace the entire motherboard. Leo would find the blown capacitor, the corroded trace, the failed power management chip. He was good.
