Haas VF Series CRT upgrade solutions — 9" mono, 12" color, 15" LCD fully compatible

About Haas CRT Display Upgrades

Haas Automation is America's largest CNC machine tool builder. CRT displays used in VF Series vertical machining centers with Haas Classic Control are fully discontinued. Common issues include screen dimming, image blurring, color distortion, and flyback transformer failure. OEM LCD upgrade kits are expensive with unpredictable lead times.

Kongto Technology offers Haas CRT-to-LCD upgrades for VF Series 9" mono (amber), 12" color, and 15" LCD displays. Modules use the original 9-pin D-Sub or 15-pin VGA connectors with DC 12V power — plug-and-play with original mounting dimensions. Installation takes 10-15 minutes.
