Frequently Asked Questions
Q: My FANUC A61L-0001-0093 CRT display is completely black. Is the CNC control still working?
Yes, in most cases the CNC control continues to operate normally even when the CRT display goes black. The CRT is a separate display component with its own high-voltage power supply. When the CRT fails, the control board still generates the video signal — you just can't see it. An LCD replacement will restore the display immediately.
Q: The display flickers or scrolls vertically. What causes this?
Vertical scrolling or flickering is typically caused by failing electrolytic capacitors in the CRT's vertical deflection circuit. As capacitors age, their capacitance drifts causing the vertical sync signal to lose lock. Replacing with a modern LCD module eliminates this permanently.
Q: The CRT image is very dim. Can I just replace the tube?
CRT brightness gradually decreases as the phosphor coating ages and the electron gun emission degrades. After 30,000-50,000 hours, brightness drops to 30-40% of original. CRT tubes are no longer manufactured. LCD replacement provides 350-450 cd/m² brightness — 3-5x brighter than a worn CRT.
Q: How long does it take to install the LCD replacement?
10-15 minutes. Power off CNC, remove CRT housing (4 screws), disconnect HONDA 20-pin signal and DC power, mount LCD, reconnect same cables, power on. No soldering, no parameter changes, no special tools. True plug-and-play.
Q: What warranty and support do you offer?
2-year warranty, lifetime technical support. In stock, ships within 24 hours. All modules 100% tested before shipping.
