Thermador Oven seems to need a new control board

My Thermador range is blinking 5 lights on preheat and 5 on heat. I am pretty sure that the control board has a problem. I have removed the board and inspected. I could not find this particular part or price. I also was not able to find a wiring diagram online. Can someone help? I was also SHOCKED at how much a pain it was to remove the board!!!

Is there any more information that I should supply? Thanks.
