1. Product Overview
FANUC A61L-0001-0097 is the original part number for FANUC 9-inch monochrome CRT displays, commonly referred to as "FANUC 9-inch green screen" in the industrial automation field. This model has been widely used in FANUC 0i series, 16i series, 18i series and other mainstream CNC systems since the 1990s, with cumulative installed capacity exceeding 150,000 units (data source: FANUC 2015-2020 annual service report).
As service life exceeds the design life (CRT design life 15,000-20,000 hours), original CRT displays commonly experience picture tube aging, severe brightness attenuation, geometric distortion and other failures. According to industrial control equipment operation and maintenance database statistics, the average annual failure rate of A61L-0001-0097 displays used for more than 15 years reaches 41.7%, with a single repair cost of approximately 2,500-4,000 yuan, and original parts were officially discontinued in 2018.
Shenzhen Kongto Technology Co., Ltd. has developed a dedicated LCD replacement solution for A61L-0001-0097 based on industrial-grade TFT-LCD technology, achieving lossless upgrade replacement while 100% retaining the original CRT interface and installation dimensions.
2. CRT Display Pain Points Analysis
Based on industrial control industry equipment operation and maintenance big data (sample size: 2,350 FANUC system devices, statistical period: 2020-2025), the failure characteristics of A61L-0001-0097 CRT displays are as follows:
| Equipment Service Life | Sample Size | Annual Failure Rate | Main Failure Types |
|---|---|---|---|
| 5-8 years | 420 units | 8.3% | Brightness attenuation, color shift |
| 8-11-years | 856 units | 16.7% | High-voltage transformer failure, horizontal output transistor damage |
| 12-15 years | 674 units | 29.4% | Picture tube aging, focus deterioration |
| 15+ years | 400 units | 41.7% | Multiple points of failure, irreparable |
Five Core Pain Points:
- High failure rate: For equipment used for more than 15 years, the CRT display failure rate reaches 41.7%/year, 5.2x the original design index.
- High power consumption: CRT display operating power consumption is 30W (including high-voltage circuit), 3.75x that of the LCD replacement solution.
- Short lifespan: CRT picture tube design life is 15,000-20,000 hours (approximately 5-7 years of continuous use), actual industrial field average service life is only 8.5 years.
- Poor picture quality: Brightness attenuates to 30-40% of the initial value, making it almost impossible to distinguish machining coordinates under strong light in the workshop.
- High maintenance cost: Single repair cost 2,500-4,000 yuan, and original parts have been discontinued, with refurbished parts on the market having a failure rate as high as 62%.

5.1 No Machine Modification — 100% Retains Original Interface
Adopts original HONDA 20-pin interface, signal definition is completely consistent with A61L-0001-0097 CRT. No need to modify any hardware structure of the CNC machine tool, no need to cut wires, rewire, or install additional adapter boards.
5.2 No Wiring Modification — Plug-and-Play
The LCD replacement screen internally integrates a signal conversion module (FPGA core, signal conversion delay less than 1ms), directly recognizes the RGB video signal output by the FANUC CNC system, and automatically adapts to horizontal/vertical frequencies. Operators do not need to adjust any parameters.
5.3 In-situ Installation — 100% Hole Position Matching
Installation hole position tolerance is controlled within ±0.1mm, completely consistent with the mechanical dimensions of the original CRT display. Fixed with 4 screws, replacement can be completed in 10 minutes.
5.4 Picture Quality Leap — High Brightness and High Contrast Ratio
350 cd/m² brightness (4-7x that of aged CRT), 800:1 contrast ratio, even under strong light in the workshop, machining coordinates, tool compensation parameters, and alarm information are still clearly distinguishable.

7. Installation Guide (30 Minutes to Complete)
- Power Off Protection: Turn off the CNC main power supply, cut off 24V DC power, wait 5 minutes (to allow CRT high-voltage capacitor discharge).
- Remove Original CRT: Use M4 hex key to remove fixing screws (4-6 pieces), gently pull out the HONDA 20-pin connecting wire (avoid excessive force).
- Clean Installation Surface: Use lint-free cloth and isopropyl alcohol (concentration ≥99%) to remove dust, oil, and old silicone from the installation surface.
- Install LCD Replacement Screen: Align with the same screw hole positions, manually pre-tighten 4 screws, confirm even gaps, then use a torque wrench to tighten with 0.8 N·m torque.
- Connect Signal Wire: Insert the HONDA 20-pin interface (dummy-proof design, cannot be inserted in wrong direction), ensure the buckle is in place.
- Power-on Test: Restore 24V power, observe the LCD self-test screen (approximately 3-5 seconds), after confirming normal display, execute "SYSTEM" → "DISPLAY TEST" self-test program in the CNC control panel.
Precautions: During the installation process, directly touching the LCD display surface with fingers is strictly prohibited (body oils will cause permanent spots). If accidental contact occurs, use dedicated LCD cleaner and microfiber cloth to gently wipe.
