A20B-2900-0155 Fanuc CRT Module

The A20B-2900-0155 is a Fanuc CRT module used in 16 / 18 CNC systems where stable display control and reliable operator screen performance are important for daily machine operation. Identified as a 16/18 CRT control board, this printed circuit board is associated with the 9 inch Option 1A display configuration.

This model is also listed as a replacement for A02B-0130-H040, which makes it especially useful for customers who are maintaining older Fanuc CRT display systems and need a correct replacement path. In real service work, the A20B 2900 0155 is often searched by customers dealing with display-related faults, CRT control problems, or legacy CNC systems where the original display hardware must be preserved.

At REACO CNC, we supply dependable Fanuc parts for customers who need replacement CRT modules, display control boards, maintenance stock, or Fanuc repair support for installed CNC systems.

The A20B-2900-0155 Fanuc CRT control board is especially relevant in older Fanuc 16 and 18 control systems that still use CRT display hardware. While many newer CNC systems use LCD screens, older CRT-based systems are still found in active production environments. For those machines, the display control board remains important because operators rely on a clear and stable screen to monitor status, alarms, parameters, and machine operation.

When a CRT control board becomes unstable, the machine may show display failure, screen flickering, weak display output, or other operator interface problems. Even if the machine control itself is still functional, an unreliable display can make operation and troubleshooting difficult. In those situations, replacing the correct A20B-2900-0155 can help restore normal display performance without changing the entire control system.

This board is commonly associated with:

• Fanuc 16 / 18 CNC systems
• CRT display control applications
• 9 inch CRT display configurations
• Replacement for A02B-0130-H040
• Maintenance and rebuild projects for legacy Fanuc controls
• Service work requiring original-compatible Fanuc display PCBs

It may also be sourced together with related display boards, operator panel PCBs, main boards, interface modules, Fanuc controller parts, servo amplifier units, spindle drive units, and other CNC electronic assemblies during broader repair work.

Depending on stock availability, this board may be supplied in:

• New condition
• Refurbished condition
• Used condition

For older CRT display systems, refurbished stock is often a practical choice because it helps preserve the original machine layout while keeping repair cost and lead time under control.

Customers usually look for the A20B-2900-0155 when they need:

• A direct replacement for a faulty CRT module
• Support for Fanuc 16 / 18 CRT display systems
• Confirmation of replacement for A02B-0130-H040
• Reliable Fanuc stock for legacy CNC machines
• Access to dependable Fanuc parts for display-related repair
• Help deciding between replacement and Fanuc repair

In real production environments, display problems can slow down repair work quickly because operators and technicians need the screen to view alarms, parameters, and machine status. Having the correct A20B-2900-0155 available can make troubleshooting easier and help return the machine to service faster.

REACO CNC supports both direct replacement supply and Fanuc repair inquiries. If your original A20B-2900-0155 is damaged, we can help review whether repair is practical or whether replacement is the better option based on stock, condition, and urgency.

We also support sourcing for related Fanuc parts, including CRT modules, display control boards, operator panel boards, main control PCBs, interface modules, servo amplifier units, spindle drive units, and other CNC electronic assemblies used in installed Fanuc systems.

For many factories, older Fanuc 16 and 18 systems are still valuable production assets. A correct A20B 2900 0155 replacement can help keep the original CRT display system working, reduce downtime, and avoid unnecessary control upgrades when the existing machine is still productive.
