FANUC A61L-0001-0094 colour CRT — convergence failure and the LCD fix

Peter Guo — Sun, 30 Aug 2026 16:52:16 +0000

Our FANUC 18i had a colour CRT (A61L-0001-0094) that developed a red/blue shadow on everything — text was unreadable after warm-up. Posting the fix in case someone hits the same.

Symptom: on a cold start the image was fine, but after 20–30 minutes a colour ghost appeared and got worse. That's classic CRT convergence drift — the deflection yoke or the convergence board is aging.

Two options presented themselves:

Repair the convergence board (realign yoke, replace drift caps) — fiddly, and it would likely drift again in a year.
Swap the CRT for an LCD panel.

Went with the LCD route. The A61L-0001-0094 is a colour unit, so the signal is analogue RGB (not the TTL monochrome type). The replacement panel needs an RGB→digital converter and the same 20-pin interface. Bonus: the LCD doesn't have convergence at all, so the ghosting problem is gone permanently, not just patched.

Worth knowing: colour CRTs run hotter than monochrome ones, so if you're still on the original tube, check the cooling fan above the display — a clogged fan accelerates the drift.

Anyone kept the colour CRT alive with a convergence repair instead? Did it hold?

FANUC CNC Display Troubleshooting Decision Tree

Peter Guo — Sun, 30 Aug 2026 16:00:19 +0000

FANUC CNC Display Troubleshooting Decision Tree
Step-by-step diagnostic flowchart for FANUC 0i/16i/18i/Series 6-18 display problems

Quick jump: Common Symptoms Decision Tree Black Screen Dim Display Flickering Repair vs Replace
When your FANUC-controlled machine's display goes dark, every minute of downtime costs money. This guide walks you through a structured diagnostic process—the same one our field technicians use—to identify the root cause and decide whether to repair, replace, or upgrade.

Section 1: Common FANUC Display Symptoms — Quick Reference
Complete black screen
No image at all. Power LED may be on or off. Most common on 10+ year old CRTs.

Dim or dark image
Image is there but very dark. Often needs "warm up" time. Classic CRT filament failure symptom.

Flickering or unstable image
Image flickers, shakes, or randomly cuts out. Usually failing video board or loose connection.

Distorted or folded image
Image is there but geometry is wrong—folded edges, wrong aspect ratio. CRT deflection circuit failure.

No video signal (CRT OK)
CRT power LED is on, brightness adjust works, but no CNC image. Problem is in the video signal path, not the display.

Color display shows B&W only
Color CRT but displaying monochrome. Loose color cable or failing color demodulator board.

Section 2: The Decision Tree — Start Here
Follow this flowchart step by step. Each decision point narrows down the problem until you reach a recommended action.

Step 1: Is the display completely black (no image at all)?
If YES → Go to Black Screen Diagnosis
If NO → Go to Step 2
↓
Step 2: Is the image dim, dark, or takes time to "warm up"?
If YES → Go to Dim Display Diagnosis
If NO → Go to Step 3
↓
Step 3: Is the image flickering, unstable, or cutting out intermittently?
If YES → Go to Flickering Diagnosis
If NO → Go to Step 4
↓
Step 4: Is there an image but geometry is wrong (folded, stretched, wrong position)?
If YES → CRT deflection circuit failure. Repair or replace CRT. LCD upgrade recommended.
If NO → Go to Step 5
↓
Step 5: Display seems fine but CNC image is missing (blank screen with backlight on)?
If YES → Video signal problem, NOT display problem. Check CNC video output, cables, and CNC system power.
If NO → Problem not clearly identified. Contact technical support.
Section 3: Black Screen — Complete Diagnosis
Check 1: Is the display power LED on?
LED OFF → No power to display. Check:
Machine main power — is the machine actually on?
Display fuse (usually on back of display unit)
Power cable connection at both ends
Panel circuit breaker (some machines have a separate breaker for the operator panel)
Fuse blown?
If the display fuse is blown, replacing it may get you running temporarily—but the CRT is likely drawing excessive current due to aging components. This is your warning sign: the CRT is on its way out. Plan an LCD upgrade soon.

Check 2: Power LED is ON, but screen is black. Shine a flashlight at the screen.
Can you see a faint image with the flashlight? → CRT filament or high-voltage failure. The backlight (for LCD) or CRT filament isn't working.
No faint image at all? → Video signal problem or complete CRT failure.
Check 3: Swap the video cable (if you have a spare).
Image appears with new cable? → Loose or damaged video cable. Replace cable (low cost fix).
Still black? → Display unit has failed. Proceed to repair vs replace decision.
Recommended action for black screen:
If CRT (9" or 14"): CRT repair is possible (replace filament, repair HV board) but cost is -500 and reliability is poor. LCD upgrade is the better choice — -850, 2-year warranty, 10+ year lifespan.

If LCD (already upgraded): LCD modules rarely fail completely. Check the external power brick (if equipped). If the power brick has a LED, is it lit? No LED = dead power brick (cheap replacement).

Section 4: Dim Display — Diagnosis and Fix
A dim display that takes 10-30 minutes to "warm up" is the classic symptom of a CRT with aging filament and weak emission. There's no practical repair—the CRT tube itself is worn out.

Quick test: Adjust the brightness/contrast potentiometer
On most FANUC CRT displays, there's a small potentiometer (knob) accessible from the front or back. Turning it may brighten the image temporarily—but if the image gets bright then quickly fades, the CRT filament is definitely failing.

Can't find the brightness adjustment?
On FANUC 0i systems, the brightness is sometimes adjusted via CNC parameters, not a physical knob. Check parameter PRM 2300 (display brightness setting). But even if you increase the parameter, a genuinely failing CRT won't respond much.

Recommended action for dim display:
Don't waste money on CRT repair. A dimming CRT is a dying CRT. The filament resistance has increased and no adjustment will restore it. LCD upgrade is the only reliable fix. The new LCD will be bright from day 1 with no warm-up needed.

Section 5: Flickering / Unstable Image — Diagnosis
Check 1: Is the flicker constant or intermittent?
Constant flicker → CRT refresh circuit or video board failure. Repair possible but unreliable.
Intermittent (comes and goes) → Loose connection or failing solder joint. Try reseating all video connectors.
Check 2: Gently tap the side of the display unit (with machine powered on and image showing).
Image changes (gets better or worse) when tapped? → Cold solder joint on the video board. Can be repaired by reflowing solder, but it's a temporary fix. The underlying board is failing.
No change when tapped? → Problem is likely the CRT tube itself or the high-voltage section.
Recommended action for flickering:
Flickering is almost always a sign of failing electronics inside the CRT display unit. Since these are 15-25 year old components, more failures will follow. LCD upgrade eliminates the problem entirely — LCD panels don't flicker (they're inherently flicker-free) and the electronics are modern solid-state.

Section 6: Repair vs LCD Upgrade — Decision Framework
Your Situation Recommendation Reason
CRT failed for the FIRST time LCD Upgrade CRT repair costs -500 and typically fails again within 12-24 months. LCD is -850 but lasts 10+ years.
CRT has been repaired BEFORE LCD Upgrade (definitely) A repaired CRT that fails again is throwing money away. Second failure rate within 12 months is ~70%.
Display is already LCD but failed Repair or replace LCD module LCD modules have 2-year warranty. If under warranty, get free replacement. If out of warranty, module replacement is ~.
Machine is being retired within 12 months CRT Repair (temporary) If the machine is going away soon, a CRT repair may be the economical choice. But consider: will a display failure cause an unplanned downtime before retirement?
You have multiple identical machines LCD Upgrade + buy spare module Standardize all machines on the same LCD module. Buy 1 spare for the whole cell. When one fails, swap in the spare (5 minutes vs 2-day wait for repair).
Section 7: Preventing Future Display Failures

Keep the display panel clean and cool
Most display failures are accelerated by heat. Make sure the machine's operator panel has adequate ventilation. If you notice the panel getting hot to the touch, add a small cooling fan. It's a investment that can add years to display life.
Use surge protection
Voltage spikes from other shop equipment (welders, large motors) can damage the delicate electronics inside CRT displays. A basic surge protector on the machine's power supply is cheap insurance.
Standardize on LCD across your shop
If you have 3+ FANUC-controlled machines, standardizing all displays to the same LCD upgrade module simplifies spare parts management. One spare module covers all machines. When a display fails, you swap in the spare and order a replacement at your leisure.

Section 8: Still Stuck? We Can Help
If you've followed this decision tree and still can't identify the problem, send us:

FANUC CNC Display Complete Compatibility Guide
Last updated: June 2026 | Covers all A61L-0001 series displays

If you're staring at a dead CRT on your FANUC-controlled machine and wondering which LCD upgrade actually works with your system—this guide is for you. We've compiled the complete compatibility matrix based on real-world installations across hundreds of shops.

Quick answer: Most FANUC A61L-0001 series 9" CRT displays can be upgraded to LCD with a direct-fit module. The key is matching your display model number to the correct CNC system family (0i/16i/18i vs Series 6/10/11). Get that wrong and nothing shows on the screen.
Part 1: Complete A61L-0001 Series Compatibility Table
This table covers every A61L-0001 display model we've encountered in the field, along with the CNC systems they work with and the correct LCD upgrade part number.

Display Model Original Type Compatible CNC Systems LCD Upgrade Plug & Play
A61L-0001-0093 9" monochrome CRT FANUC 0-TC, 0-MC, 16T, 18T, 16M, 18M, 0i-A/B/C KT-0093-LCD Yes ✓

Note: "KT-" part numbers are Kongto Technology upgrade modules. OEM part numbers may vary by region.

Part 2: How to Identify Your Display Model
Before ordering anything, you need to confirm exactly which display you have. Here's how to find it:

Step 1: Check the front bezel
Most FANUC displays have a label on the front bezel or around the edge of the screen. Look for "A61L-0001-XXXX" printed on it. If the label is faded (common on 15+ year old machines), move to Step 2.

Step 2: Check the back of the display unit
Remove the display from the machine panel (usually 4 screws). The model label is on the back, often near the video connector. Take a photo of it—you'll need it when ordering the upgrade module.

Step 3: Measure the screen diagonal
This tells you whether you have a 9" or 14" display:

9" display: A61L-0001-0090/0092/0093/0095/0096/0097/0086
14" display: A61L-0001-0094/0074
Step 4: Confirm your CNC system model
On the CNC control panel, look for the system name: "FANUC 0i-MC", "FANUC 18i-TB", etc. This appears on the boot screen and in the system info (press SYSTEM → → → SYSTEM INFO).

Pro tip: If you're unsure, send us photos of the display front, back label, and CNC system boot screen. We'll confirm compatibility within 2 hours during business days.
Part 3: CNC System Family Compatibility Details
FANUC 0 Series (0-T, 0-M, 0-TT, 0-MT)
The original 0 series from the 1980s-1990s uses 9" monochrome CRTs. These are the most straightforward upgrades—the LCD module connects to the same video cable (Honda 12-pin or 20-pin depending on the model).

A61L-0001-0093 A61L-0001-0090 A61L-0001-0092

FANUC 0i Series (0i-A, 0i-B, 0i-C, 0i-D, 0i-F)
The 0i series is the most common FANUC control in shops today. 0i-A/B/C typically use 9" monochrome; 0i-D and later can use color LCDs. The LCD upgrade modules for 0i systems include power regulation to handle the different voltage requirements.

A61L-0001-0093 A61L-0001-0095 A61L-0001-0096 A61L-0001-0097

FANUC 16/18/21 Series (16i, 18i, 21i)
These higher-end systems from the early 2000s use both 9" and 14" displays. The 14" color CRT (A61L-0001-0094) is a color display that our 12.1" LCD upgrade kit replaces with the correct video timing support.

A61L-0001-0094 A61L-0001-0096 A61L-0001-0097

FANUC Series 6/10/11 (Older systems)
These are the vintage FANUC systems from the 1980s. The A61L-0001-0086 (Panasonic CRT) is the one you'll see. The video signal is standard RGB, so the LCD upgrade is actually simpler than newer systems.

A61L-0001-0086

Part 4: LCD Upgrade vs CRT Repair — Which Makes Sense?
Factor CRT Repair LCD Upgrade
Upfront cost -500 -850
Expected lifespan 1-3 years (CRT wears out) 10+ years (LCD)
Installation time 1-2 hours 30-60 minutes
Spare parts availability Very limited (CRT discontinued) Readily available
Image quality Flickering, dim Sharp, bright, no flicker
Power consumption ~40W ~12W
3-year TCO -1200 (repairs add up) -850 (one-time)
Bottom line: If your CRT has already been repaired once, go straight to LCD. The second CRT failure usually happens within 12 months, and at that point you're throwing good money after bad.

Part 5: Installation — What's Actually Involved
One of the reasons our LCD upgrade modules work well is that they're designed as drop-in replacements. Here's what the process actually looks like:

What you need (total time: 30-60 minutes)
Power down the machine — Lock out tag out. Wait 5 minutes for capacitors to discharge.
Remove the CRT bezel — Usually 4 screws on the front, or clips on the side.
Disconnect the video and power cables — Take a photo of the connector orientation before unplugging.
Unmount the CRT — CRts are heavy (8-12 lbs). Get a helper.
Mount the LCD upgrade module — The mounting holes align with the original CRT bracket. No drilling.
Connect cables — Same connectors. If the upgrade module has a small external power brick, mount it inside the panel.
Power on and test — You should see the FANUC boot screen within 5 seconds.
Safety note: CRT displays contain high-voltage capacitors (up to 15kV). Even after power-off, these can retain a dangerous charge. If you're not comfortable working inside the display panel, have a qualified technician do the installation.
Part 6: Frequently Asked Questions
Q: Will the LCD upgrade work with my FANUC 0i-MF (latest generation)?
A: The 0i-MF uses a different display interface (often HDMI or proprietary digital). Our upgrade modules target the CRT/early LCD generation (0i-A through 0i-D). For 0i-F and later, check with us—some models can be adapted, others need a different solution.
Q: My display says "Matsushita" not "FANUC"—is that the same thing?
A: Yes. Matsushita (Panasonic) manufactured many of the CRT displays that FANUC rebranded. The D9MM-11A is functionally identical to the A61L-0001-0093 for compatibility purposes.
Q: Can I keep a spare CRT as backup after installing LCD?
A: Technically yes, but it's unnecessary. LCD upgrades are solid-state with no filament to burn out. In 5 years of selling these modules, we've had exactly 2 warranty claims (both were shipping damage, not component failure).
Q: Does the LCD upgrade affect CNC system parameters?
A: No. The LCD module is passive—it receives the video signal and displays it. It doesn't communicate with the CNC system, so no parameter changes are needed. Plug it in, turn it on, done.
Q: What if my A61L model isn't listed in the table?
A: FANUC made dozens of display variants. If your model isn't in our table, send us photos of the display and CNC system. We maintain a private compatibility database with over 200 FANUC display variants and can usually identify the correct upgrade within a few hours.
