    Were are you located?

    I've never come across that brand. But I suspect it may be a Rational

    Oh, and if the board is going blank, it is usually a communication wiring problem or voltage supply

    It can also be a environmental problem like high temperatures or humidity in the kitchen.

    Does the unit have a water supply like a Combi oven?

    Emily Andelin Hughes, I did some digging on this and it seems it's a domestic oven that I can't get past their firewalls for documentation. This site is primarily for commercial equipment tech's. But the idea of a catalytic heating system is intriguing to say the least. I'm not certain were to send you as they are not sold in the North America.

    If you have a wiring schematic for it I would be willing to look at it and maybe provide a bit of insight as to if it has safeties or something simple. But I suspect you may be having a control board thermo failure due to the age. Most of the equipment we see has cooling fans for the control board. They are just small muffin fans that die after 8 to 10 years of service. And electronic controls don't fair well at higher temp's.
