KitchenAid Display Trouble

We just ordered a new control panel for or KitchenAid KGRC608LSS0, hoping it would make our display work again. We properly installed the control panel and nothing lights up on the display. The outlet is working properly. The stove is getting power in general (the electric ignition for the burners work), but no display. Any thoughts?

When we took the other board out, we may have done so without unplugging the stove. Would that matter? Is there a fuse anywhere that might need to be replaced?
