it uses 2 LM7812 one per each 2 IR21844S, and both measures are fine on the main board without the driver board, just for make sure think i will replace those too , thanks again Perry.The 12v regulator is common to all of the drive ICs and when one IC fails, it destroys the regulator and the other driver ICs. Have you confirmed that the regulator and the other ICs survived?
