Is the FAGOR 8055 LCD replacement compatible with the 8050 model too?

Yes. The FAGOR 8050 and 8055 use the same display interface and signal protocol. The same LCD module works for both models.

Does the replacement void the FAGOR control warranty?

The LCD replacement is completely reversible — the original CRT can be reinstalled at any time. No modifications are made to the control board itself.

What is the brightness improvement over the original CRT?

The original FAGOR CRT is approximately 200 cd/m² when new. Our LCD module delivers 400 cd/m² — double the brightness, with zero flicker and no geometric distortion.

FAGOR 8055/8050 CNC CRT to LCD Custom Replacement — Case Study

FAGOR 8055 and 8050 CNC controls are widely used on milling machines, lathes, and machining centers across Europe and Asia. Their built-in CRT displays are a known weak point — after 10-15 years, the CRT tubes dim, colors drift, and the high-voltage section becomes unreliable. This case study shows a successful FAGOR 8055 CRT-to-LCD conversion using a custom 10.4-inch replacement module.

The Challenge

The customer operated several FAGOR 8055-controlled machining centers. Three units had CRT failures within the same month — two with dim/faded displays and one completely dead. FAGOR no longer supplies CRT replacements for these models. Quoted control swap costs exceeded $4,000 per machine plus weeks of downtime. The customer needed a fast, reliable, cost-effective solution that restored full display functionality without replacing the entire control.

The Solution

We developed a custom 10.4-inch TFT LCD replacement specifically for the FAGOR 8055/8050 display interface. The module reads the FAGOR's RGB/TTL video signal directly — no external converter, no frame grabber, no software changes. The LCD panel mounts using the original CRT housing holes with a precision adapter bracket. DC 24V power is drawn from the same rail the CRT used. The result is a completely reversible upgrade that requires zero modifications to the CNC control.

Installation & Results

The replacement was performed on all three machines in a single day. Each installation took approximately 20 minutes: power down, remove CRT bezel, disconnect signal and power, mount LCD with adapter bracket, reconnect, power up. All three FAGOR 8055 controls displayed correctly on first power-on. The operators reported dramatically improved readability — the 400 cd/m² LCD was more than twice as bright as the worn CRTs, with perfect geometry and zero flicker at 60 Hz.
