Hello All, my 2015 S550 has an odd issue with the Speedometer screen. The right screen (audio) works fine.

Below are the symptoms:
*Black with no back lighting - was intermittent but now seems to be black more often than working
*Parking sensors and Disctronic is not active for lane keep assist, etc.

I held the CD player eject button down to reset the system and it managed to turn it back on once, but hasn't worked since. I also removed the relevant fuses (317-322, could not get MF2 loose) from the fuse box in the right foot well, but they all looked great and it didn't do anything.

The dealer could not find any codes, so I'm hoping for a little guidance given that the lack of screen is impacting other systems. Is this common? Is there a trouble shooting path beyond what I've done so far?

Thanks for any help!
