I've been trying the fix a controller unit for some time now, so far i've replaced a few blown and shorted parts and now the board is powering up now. However, one of the mosfet is not switching on, I noticed that there wasn't a signal coming to the gate, which comes from SAFC167CR-LM HA+ MCU (Pin 19). I can replace the MCU but the real question is do these MCU have specific codes programmed to them or i can just replace the MCU without programming anything?
