Wiped down interior, screen stopped working.

I think I've seen someone post about this before but I cannot find it now.

All of my cleaning was done with the car off which is why this has me stumped. There shouldn't have been any inputs that had any effect.

It's not the mute button. Holding it will black out the screen, holding it again will make it glow (if you're a computer nerd and you know what IPS glow is, that's it). It makes the little chime when you hold it.

It's not the brightness dial by the speedometer. Turning that has the same effect--turns the screen on and off but there is no UI.

I've tried just about every other button combination I can think of.

The screen just glows but there is no UI, no backup camera, nothing.

Any ideas?

How about a soft reset ?

Try press and hold the volume button?

Does the radio come on?
Any devices connected via USB cable or USB drive, maybe for AA or ACP?
Have you tried holding down the "Home" button to switch into/out of AA/ACP?
Try a soft reset. Press and hold the Volume, Navigation and Back buttons at the same time, holding for about 10 seconds until the infotainment resets.
I've also come across a diagnostic mode posted by a user on Reddit, who also happens to be a member here. If you press and hold the Music, Favorites and Volume buttons, you enter a diagnostic mode. If you then choose "End Diagnostic Mode", the infotainment will reset.

If all that fails, I'd try disconnecting the battery for like 10 mins.
