Technically yes, but it requires opening the display housing, discharging high voltage (inverters can hold a charge), and handling fragile CCFFL tubes. Unless you have experience, we recommend sending it to us or replacing the unit. The cost of a new CCFFL tube + your time usually exceeds the cost of an LCD upgrade.

The display panel itself can last 15+ years, but the backlight (CCFFL tubes) typically fails after 8–11-years of normal use. The inverter (which powers the backlight) often fails around the same time. This is why LCD upgrades are so popular — you keep the good LCD panel but replace the failing backlight system with reliable LEDs.

Yes. Our LCD upgrade kits are signal-compatible with the original Siemens display. They accept the same video signal (SVGA/XGA depending on model) and mount in the same cutout. No software changes needed — it's truly plug-and-play.

Absolutely. We offer a diagnostic service — send us the display, we'll tell you exactly what's wrong and give you a repair or replacement quote. If you proceed with us, the diagnosis is free. Turnaround is typically 2–3 business days.

We stock LCD upgrade kits for all common Siemens SINUMERIK displays (6FC3988 series, SM0901, and others). Most orders ship within 24 hours. If you need a custom configuration, lead time is typically 5–7 business days.
