HAAS Automation PCB 65-3400C Circuit Board

HAAS 65‑3400C is a Video/Floppy interface PCB used in 65‑series CNC controls to provide data storage and HMI connectivity. Common failures on this board include burned or cracked surface‑mount components (especially the 12 V regulator), loose or corroded socket contacts, and damaged trace vias that interrupt video signal paths. Initial diagnostics should verify the 12 VDC supply rail, inspect for visible component damage or solder bridges, and check I/O continuity on the video/floppy connectors before proceeding to more detailed board testing.[oss-gpt-20b]
