Kenwood Car Stereo won’t load. Fuse?

The Kenwood car stereo touch screen won’t fully load. It starts up but then screen goes black then back to main screen again. Replaced car battery recently for other reasons. If fuse what size? In picture the screen visible is what won’t come up.

 

If its turning on but then turning off again i doubt its a fuse. I would think a blown fuse wouldn't allow it to turn on at all. Could the actual head unit be bad?

 

Fuse is either on or off. Not really boot looping. That's going to be a software issue of some sort. Is there a possibility of getting to the settings menu to do an update? Or maybe a way to download the whole firmware and do a manual load of it?
