HAAS Automation 65-3200 Video/Floppy Interface

The HAAS 65‑3200 Video/Floppy Interface is an OEM circuit board that connects the machine’s control system to external video displays and floppy drives, commonly used on older Haas CNC controllers. Common failure modes for this class of interface boards include burned or cracked capacitors, damaged trace connections from vibration or thermal cycling, and degradation of the video output driver ICs. Begin troubleshooting by verifying 24 V DC power to the board’s supply rails, inspecting for physical signs of component damage or solder bridges, and checking the integrity of the video signal path with an oscilloscope or multimeter across the display connector pins.[oss-gpt-20b]
