Electronic info screen went dark. everything works but screen is dark.
You can check with an automotive sound system store, but I suspect the screen is integral and the entire system requires replacement.
I’d start by pulling out my manual and looking in the section about screen settings to ensure the screen was not somehow turned off or dimmed first. I’ve shut off screens in test cars accidentally a few times.
Check for loose connections going to the display unit and make sure power is getting to it.
