Vent hoods are typically hardwired to the circuit breaker box, but they can also be plugged into a wall outlet behind the cover panel. In either case, it may be difficult to test the incoming power to the vent hood without removing a large cover panel. If the unit is plugged into an accessible wall outlet you can plug another small appliance into the outlet to confirm there is power. If you cannot access the incoming power connection easily, confirm the circuit breaker suppling power to the vent hood has not tripped.
Most range vent hood control boards have the buttons attached to the board. If you've determined that power is reaching the board, then it's likely the control board is defective and will need to be replaced. If there is a separate touchpad, it would be a good idea to replace both the control board and touchpad at the same time.
