The Driver chip module can be removed and replaced , do not believe that the mother board is fried only Driver chip module.

Modules are around $10 dollar or so. When replacing watch for pin placement and module type.
Make sure driver module is plugged in correctly before applying power or you may cause new module damage.

After you remove the bad module you can power 3D Printer back on to verify unit powers on an steppers with driver modules function.
You can also measure the power supply output and adjust for correct voltage 12.0V for 12 volt supply an 24.0v for 24volt supply.
Adjusting the power supply too far above the suggested supply voltage can have adverse effects on how your 3D Printer functions.
Measure power supply output voltage using the DC scale on your digital multimeter.
