Run ARCNET diagnostic to make sure that you have good communication with this board ( other boards also ) .

After laser control pcb changing you have run software upgrade ( enough for this board - service mode, software upgrade from HD ) . Also have load backup ( enough for this board - service mode, read write data, service data ) .

Did you do a software upgrade on the board?

not sure.. in fact my engineer was doing that job.

I will check service manual for the procedure of "Software upgrade" on the board, thanks to pepe21 Sir
