CRT displays were discontinued 15 years ago. Repairs use donor parts just as old and fail again in months. LCD upgrade costs 150 to 300 dollars once and lasts 5 to 7 years. FANUC uses Honda MR-20M DC24V. Mitsubishi uses 20-pin DC24V. Mazak uses 26-pin DC24V. Siemens SINUMERIK uses AC110V DB-25 which is different. Installation takes 10 minutes: power off remove 4 screws unplug CRT connect LCD mount power on. No parameter changes needed. Full reference at cncdisplay.com.</p> cnc manufacturing industrial tutorial
