About Siemens CRT Display Upgrades
Siemens SINUMERIK is one of the most widely used CNC control systems in high-end machine tools. The CRT displays (6FC3988-7FA20, SM0901, 6FC5200 series) have been discontinued for years, with common failures including flyback transformer burnout, display dimming, and startup issues. OEM replacement parts are extremely expensive.
Kongto Technology offers Siemens SINUMERIK CRT-to-LCD upgrades covering 6FC3988-7FA20, 6FC5200 series, and SM0901 models. LCD modules use the original DB-25 connector and support AC 110V/220V power supply — no CNC parameter changes needed. Installation takes 15-20 minutes.
