Explosive Range

While using the oven and 3 burners on the cook top I heard a loud pop and bright flash come from under the right side of the cook top control knobs. After unplugging the range and resetting the circuit breaker the cook top would work but not the center control panel for the oven temp or clock/time. I have disconnected the range and removed the rear top panel behind the control section of the range and have found nothing visibly broken, burnt, discolored, or foreign objects. I have a feeling the control panel is the culprit. Any ideas???
