The FANUC A20B-8002-0702 is an LCD inverter PCB used with compatible FANUC Series 0i-D and 0i Mate-D CNC control systems.

FANUC maintenance documentation identifies this board as the inverter for a 10.4-inch color LCD. It forms part of the LCD display assembly and supports the electrical operation of the screen’s backlight system.

The A20B-8002-0702 may be used in applicable 0i-TD, 0i-MD, 0i Mate-TD, and 0i Mate-MD configurations equipped with the corresponding 10.4-inch color display. Compatibility still depends on the complete control-unit specification and display configuration.

This board is suitable for replacement when a confirmed inverter fault causes the LCD backlight to fail, become intermittent, remain unusually dim, or prevent the display from illuminating normally.

Because a dark or abnormal screen can also be caused by the LCD panel, main board, power supply, cable, or display-signal circuit, the fault should be properly diagnosed before replacing the inverter PCB.
