Upgrade Your FAGOR 8025 CRT to LCD: A Complete Guide

The FAGOR 8025 CNC controller has been a reliable system in industrial environments for years. But if your unit still runs on a CRT monitor, you’re probably dealing with screen burn, poor visibility, and failing components. T2 Industrial offers a practical solution: the 6.4″ LCD Upgrade Kit with Keypad Overlay, designed to replace the aging CRT and extend the life of your control system.

This guide explains what’s included in the kit, why it matters, and how to install it step-by-step.

Why Replace Your CRT Monitor?

CRT monitors are outdated. Over time, they:

• Become dim or distorted
• Consume more power
• Take up more space
• Are harder and more expensive to repair

Upgrading to an LCD improves screen clarity, reduces energy usage, and prevents future downtime — all without replacing the entire controller.

What’s in the Upgrade Kit?

The 6.4″ LCD Upgrade Kit with Keypad Overlay is built to fit the original FAGOR 8025 layout. It includes:

• A 6.4″ industrial LCD screen
• A new front panel with integrated keypad overlay
• Wiring harness
• Power connection options (MAP302 or MAP307)
• Mounting hardware and support
• Full compatibility with your original system I/O

The result is a clean and seamless upgrade that maintains the functionality of your FAGOR 8025 while improving visibility and performance.

Installation Process

The installation process is divided into four key stages: removal, installation, setup, and troubleshooting.

Part 1 – Removing the Old CRT

Over time, keypad overlays on industrial machines can wear out due to:

1. Power Down

   • Turn off the main machine and power breaker.

   • Unscrew the HMI from the front panel.

   • Take a reference photo of all connections.

   • Unplug all communication and power cables.

2. Access Internal Components

   • Remove thumb screws and detach the I/O card.

   • Unscrew the four nuts holding the CRT monitor.

   • Open the back cover and disconnect the CRT power cable.

3. Detach Front Panel

   • Remove the front panel by unscrewing the hinge.

   • Unplug user control and video cables.

   • Detach the video board and remove the CRT screen.

Part 2 – Installing the LCD Upgrade

1. Attach New Front Panel Components

   • Mount the PCB and selector switch onto the new panel.

   • Plug in the keypad overlay cable.

   • Secure the hinge bracket using existing studs and nuts.

2. Reconnect Cables

   • Plug in the user control cable.

   • Reconnect the video cable and attach the ground wire to C13, JP5, or JP6.

3. Connect Power

   • Choose a power option:

     • MAP307: Crimp and connect red wires, attach ground.
     • MAP302: Plug into existing outlet or extension cord.

Part 3 – LCD Setup and Configuration

1. Turn On and Access Menu

   • If there is no video signal, the screen will turn blue.

   • Use the 3 control buttons on the back of the LCD:

     • MENU to open settings

     • LEFT/RIGHT to navigate and adjust

     • Settings save automatically or after 20 seconds of inactivity

2. Fine-Tune Video Settings

   • WIDTH: Adjust screen width and fix vertical lines

   • HEIGHT: Adjust screen height

   • H_POSITION / V_POSITION: Align the screen properly

   • PHASE: Eliminate visual flicker

   • STYLE: Set to RGB(A); switch to YUV for grayscale video

   • SYNC: Auto-detect; adjust if needed

   • RESISTANCE: Use 75Ω if colors are overly saturated

   • RESOLUTION: Default is 800×600; change to 640×480 if needed

Part 4 – Troubleshooting Tips

1. No Video Signal?

   • Check video cable connection

   • Confirm “Info” screen isn’t showing 00.00 (means no signal detected)

2. Saturated or Blooming Text?

   • Change resistance from 750Ω to 75Ω

3. Image Tearing (Top Left)?

   • Slightly adjust HS potentiometer (clockwise or counterclockwise

4. Blurry or Doubled Image?
   • Adjust the VS potentiometer
5. Resetting Video Pots (if needed):

   • Horizontal: Turn clockwise until it clicks, then turn counterclockwise 3 full turns

   • Vertical: Turn clockwise until it clicks, then turn counterclockwise 16.5 turns
