Unreadable display on Dacor Oven

After a "boil over" on the stove top, the display on the oven is now unreadable. Everything works on the oven, but the digital numbers are unreadable. I can still use the oven (knowing that when I turn it on it is 350, and each press of temp up increases it 5 degrees).

I am hoping for a simple remedy, like a reset code. If not, then perhaps any advice on what parts need to be replaced with some basic instructions.

Thanks in advance,
Casey
