GE range light caused controls to go out

Lightning struck near our house a week ago and the electricity went out. We heard a loud "pow" in the house when it did. When the electricity came back on, everything worked but the oven. The stovetop works fine, but the oven control panel would not light up or work. It was diagnosed as the circuit board and we replaced it today. The control panel lights came on and the clock and oven seemed to be working. When I pushed the light control, there was a loud "pow" and the control panel went out again. Why would this happen and did it burn out the circuit board again?
