  • Display-control processing for an 8.4-inch color LCD
  • Graphics and embedded-Ethernet functions associated with the base card
  • Revision-specific /04B replacement identity

A20B-3300-0281/04B is identified by the complete FANUC board number and revision suffix. FANUC maintenance documentation associates base card A20B-3300-0281 with the 8.4-inch color-LCD display-control position in supported i Series assemblies.

The card should be purchased from the actual label, not from the A20B family prefix. LCD size, CNC series, main-board relationship, connector population, software generation and /04B revision all need to agree with the removed assembly.

Availability, condition, price, and shipping time for A20B-3300-0281/04B are confirmed during quotation.

  • Photograph every display and control cable before disconnection
  • Protect the board from electrostatic discharge during handling
  • Inspect LCD cable contacts and connector locking features before reassembly
  • Verify the CNC boots to a stable full-color display
  • Test all panel keys and soft-key pages used by the machine
  • Confirm Ethernet diagnostics and alarm history when that interface is installed
  • Display-control processing for a compatible 8.4-inch FANUC color-LCD panel

  • Revision-matched maintenance replacement for an installed A20B-3300-0281 card
Description
A20B-3300-0281/04B provides display-control functions within a compatible FANUC CNC panel or control unit. The base A20B-3300-0281 identity appears in FANUC maintenance documentation as an 8.4-inch color-LCD display control card with graphics and embedded Ethernet functions.

The /04B suffix identifies the delivered hardware revision and must remain on the purchase request. A visually similar card with another suffix may differ in component population, connector arrangement or supported control generation.

Before transfer, record the host CNC series, panel model, slot or mounting position, cable orientation and all label strings. After installation, test video, keypad or soft-key response, Ethernet where used, CNC boot behavior and alarm history before returning the machine to production.

Technical notes
A20B-3300-0281/04B must be matched by the /04B label, 8.4-inch display assembly, connector population, host CNC generation, cable orientation, software backup, graphics behavior, and embedded-Ethernet requirement.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Is Fanuc A20B-3300-0281/04B a main CPU board or a display card?
FANUC documentation identifies the A20B-3300-0281 base number as an 8.4-inch color-LCD display control card, so it should not be listed as a CNC CPU.
Can a Fanuc A20B-3300-0281 with a different suffix replace Fanuc A20B-3300-0281/04B?
Not by base number alone. Compare the full label, board revision, connector population, component layout, host CNC series and panel assembly before approving another suffix.
What photos are useful when sourcing Fanuc A20B-3300-0281/04B?
Provide clear images of both board faces, the A20B label, every secondary sticker, edge connectors, LCD or panel label and the host CNC nameplate.
What should be backed up before exchanging Fanuc A20B-3300-0281/04B?
Back up CNC parameters, offsets, PMC data and any panel or Ethernet configuration required by the machine, following the maintenance procedure for the installed control.
Why might Fanuc A20B-3300-0281/04B produce no display after installation?
Check host power rails, connector seating, LCD cable orientation, panel compatibility, card revision, main-board communication and any alarms visible through another diagnostic method.
Does Fanuc A20B-3300-0281/04B include the LCD or operator panel?
Do not assume so. The board description identifies a display control card; the quotation must separately state whether the LCD, panel, cables or mounting hardware are included.
Which acceptance tests matter for Fanuc A20B-3300-0281/04B?
Confirm stable video, correct colors, soft-key and keypad operation, CNC startup, Ethernet communication where used, alarm-free running and warm restart of the complete machine.
