Command Not Turning On 2014 GL450

Hi, yesterday i was driving and when i started the drive everything was working perfectly I could see the 360 camera fine radio worked but as I pulled into my destinations parking lot the command screen tried to boot up 2-3 times while the car was still rolling it would reach the warning note after the Mercedes symbol and reboot i turned off the car went to my destination came back and turned the car back on the command screen would not work and neither did the radio the climate control settings and the heated seat buttons worked fine under the screen. Any suggestions would be helpful i live about 200 miles away from the nearest dealer and have a pretty tight schedule. Thanks!

Yes, it ended up being a dead power supply.

thanks, that’s what I figured. Mine is getting sent to FL to repair and I suspect the same happened to mine. Tested all the terminals and fuses, all seen to be fine, so the radio is the only thing not working. Hopefully it’s a small fix like this, instead of the motherboard.
