- Remove 4 mounting bolts from the CRT bezel
- Disconnect the 26-pin proprietary cable
- Connect same cable to the replacement LCD module
- Mount LCD using original screw holes (same pattern)
- Power on — no CNC parameter changes required
Total time: ~15 minutes. The LCD draws DC 24V, matching the original CRT power supply.

Technical Details
The C-5470NS CRT in Mazak systems connects via 26-pin proprietary and runs on DC 24V. It's compatible with Mazatrol T-32, Mazatrol M-32, M-Plus controls. The LCD replacement uses the same connector and power — no adapter needed. Price: $249.
Phosphor burn-in is permanent. That ghosted CNC parameter screen is etched into the tube. LCD modules use TFT technology — no phosphor layer, no burn-in, ever.
