Power surge furnace dead now

Had a power surge do to power lines going down. Several light bulbs burnt out in house and breakers popped. It appears that there is no power going to the control board on the furnace now the indicator light will not light up. The fuse on the out side of the furnace was blown, I replaced that and that’s as far as I’ve gone. any ideas where to start checking? Thanks

Check the transformer connected to the control board.
