dash display not workin

Check fuses and I'm not being trite, but is it all possible the dimmer was accidentally actuated?

The dealer reset the codes yesterday & it worked fine for a few hours & then went blank again. The Speedometer & gas gauge isn't working. It doesn't move when accelerating or show if I fill up my tank. I can't view those two things or my display.

well i had the same problem and it was to hard to figure what was wrong,, after almost a year replacing parts finally fixed,, it was not the screen, it was the head until ( cd player until) and the dealership said it might cost over 8 k to be replaced ( that’s for my model part) genesis comes with few different types of head unit and screen,, and i finally got one used from a guy in california he just know about this parts and he got a excellent knowledge abut it. i got it for 900$ and problem resolved

It happen yesterday, I pull all the fuses one at a time and put it back. That's all my dash working fine.
