Summary: Complete plug-and-play LCD replacement guide for FANUC A61L-0001-0093 (D9MM-11A) 9" monochrome CRT display. Kongto KTO-F0093 module delivers 800×600 resolution, 350cd/m² brightness, uses original Honda MR-20M connector and DC 24V power —no CNC parameter changes needed. Install in 10-30 minutes with 2-year warranty.
⚠️ Quick Answer: Yes — the FANUC A61L-0001-0093 (9-inch CRT used in FANUC 0-series and 0i controls) can be replaced with a plug-and-play industrial TFT-LCD module from $155. The retrofit uses the original wiring and connector, installs in about 30 minutes with no CNC parameter changes, and carries a 2-year warranty.
I. Equipment Status and Original Specifications
The FANUC A61L-0001-0093 is one of the most widely used 9-inch monochrome CRT displays in FANUC CNC systems, commonly found in FANUC 0 series, 0i series, and OM-D CNC systems. This display uses cathode ray tube technology with a designed lifespan of approximately 15,000 hours (about 3-5 years under 3-shift operation).
Original CRT Key Parameters
Item Specification
Model A61L-0001-0093
Display Technology 9-inch Monochrome CRT (Cathode Ray Tube)
Display Color Green / Amber Monochrome
Resolution 640×400 pixels
Signal Interface HONDA 20-pin
Power Input DC 24V (from CNC host)
Power Consumption 25-30W
Operating Temperature 0~40°C
Mounting Dimensions Standard 9-inch CRT mounting holes
Common Aging Faults
Units in service for over 5 years commonly exhibit the following issues:
Brightness Attenuation: CRT cathode ray tube aging causes brightness to drop by over 50%, making the screen difficult to view during daylight
Poor Focusing: Blurred character edges and distortion, leading to parameter reading errors during programming
Flickering and Jitter: Aging high-voltage circuits cause image instability, leading to operator fatigue during prolonged use
High-Voltage Safety Hazard: High-voltage package inside CRT (anode voltage approx. 10-15kV) poses electric leakage risk
Complete Blackout: Filament burnout or high-voltage package failure, rendering the equipment inoperable
II. LCD Replacement Solution
Kongto Technology provides a dedicated A61L-0001-0093 LCD retrofit module, using industrial-grade TFT-LCD display panel to perfectly replace the original CRT.
System Compatibility
This LCD retrofit solution is applicable to the following FANUC CNC systems:
FANUC Series 0 / 0-Mate / 0-TMate
FANUC Series 0i-A / 0i-B / 0i-C / 0i-D
FANUC Series 16i / 18i / 21i
FANUC OM-D / OM-C CNC units
All CNC machine tools equipped with A61L-0001-0093 display (machining centers, lathes, milling machines, grinders, etc.)
IV. Installation Procedure (Approx. 30 Minutes)
Power Off and Remove
Cut off CNC system main power, remove 4 fixing screws from CRT display bezel, disconnect HONDA 20-pin signal cable and DC 24V power cable from the back.
Install LCD Module
Place the LCD retrofit module into the original CRT mounting position, align mounting holes, and secure with original screws (keyed design, cannot be installed incorrectly).
Connect Cables
Insert HONDA 20-pin signal cable into LCD module signal port (with keyed connector, cannot be inserted incorrectly), connect DC 24V power cable.
Power On and Adjust
Restore power supply, LCD displays automatically after system boot. Use OSD buttons on the front panel to fine-tune brightness, contrast, screen position and other parameters.
Multi-System Compatibility — Tested Across FANUC Platforms
The A61L-0001-0093 LCD replacement kit has been rigorously tested and validated across multiple FANUC CNC control systems. Our engineering team verified compatibility on the following platforms to ensure reliable plug-and-play operation regardless of your specific FANUC configuration:
FANUC 0iM System — Most common FANUC milling control, widely used in machining centers
FANUC O-T System — Lathe/turning control with 9-inch monochrome CRT
FANUC O-MD System — Older milling/drilling control with standard CRT interface
FANUC TOME System — Specialized control variant with custom display requirements
Usage Advantages and Maintenance Recommendations
Core Advantages
Plug-and-Play: No equipment structure modification needed, upgrade completed in 30 minutes
Improved Display Quality: High brightness, no flicker, wide viewing angle, adaptable to various lighting environments
Reduced Power Consumption: Power consumption is only 1/3 of original CRT, reducing CNC cabinet heat dissipation burden
Extended Lifespan: Industrial-grade LCD lifespan is 3x+ that of original CRT
No High-Voltage Hazard: Entire unit low-voltage powered, eliminating CRT high-voltage leakage safety risk
Long-Term Maintenance Recommendations
Periodically (every 6 months) check if signal cable connectors are loose
Maintain good ventilation in electrical cabinet, avoid long-term high-temperature operation
Periodically calibrate brightness and contrast through OSD menu
If display abnormality is found, prioritize checking if HONDA 20-pin connector is oxidized
