I have a microwave (model #PSB1201NSS01) the display control board (WB27X10858) and and display board - digitron (WB27X10856) have been replaced with new parts, but the version of the two boards is not the same. The digitron is rev G. Is there a way to order a display control board of the same firmware so the boards can communicate or could something else be causing the display control board to not sync with the display board.

If the low voltage transformer is not sending proper voltage, it can cause this issue. At connection CN7 of the power control board, there should be 12 Volts DC when testing from the wire at pin 1 to the wire at pin 5, 19 Volts DC from the wire at pin 3 to the wire at pin 5, and 7 Volts DC from the wire at pin 4 to the wire at pin 2. Does the voltage at the power control match this or is it different?
