Display / controls are gone.

Hi, early last week I stopped seeing any of the controls or numbers on the oven (just the start/stop button) and tried contacting anova, but they have yet to respond. Today the display/controls are totally out. Wifi still works so I’m not totally out of luck.
Is there a fix for this somewhere? Maybe a loose cable that only requires minor oven surgery to fix?

I should note that power cycling the oven will bring the display back for a short period of time.
