[My Benz]

I had a scare today when I noticed that my command screen on my 2019 GCL 300 went black. When I put the car in reverse, it worked fine, but when I started driving, the navigation screen, the radio screen and the media screen was black. After I got home a few minutes later, I turned my SUV off and on again couple of times, and each time it was black. The only time the screen came on was when I pressed the 360 degree FOV or put the car in reverse. That told me that the screen worked, just something else wasn't working. I went online to see if anyone else has a similar problem. On MBworld, I found a thread on it. Someone mentioned that the volume button also acts as a power button. I went back out to the SUV, powered it on and tried that. Again it did not work. For a moment there I thought I might have to take my new Benz in to have it service. I then took a closer look at the layout of the console near the armrest, and saw there was a power button. I pressed it, and it worked. Command screen came back to life. Up until now, I did not notice there was a power button there. That same power button turn the command screen off and effectively turn off the entire command console, navigation, radio and media off. This also reminded me of a thread that someone posted awhile back asking if there was a way to turn off the radio. I believed more than one person replied was to hit the mute button and that worked similar to turning off the radio. At the time, I thought that was a silly design by Mercedes. Now that I know there IS a power button, whether it be an actual power button or a power button built into the volume knob, I'm the one now who feels silly. As to how I managed to turn off my command screen without knowing it, it was because I put a small bag of items I bought from Lowes and one of the items was just enough to hit the power button and turned it off.

Gosh I am so glad you made this post!! I would have probably gotten hit over the head for a needless repair. 💕 My puppy pushed the power button cans I went in panic mode when I saw the blank screen.

Thanks one million

Pressing and holding the eject button on the CD player also reboots the system, I've had the blank screen happen once and I tried the reboot and it worked.

Thank You Victor! This fixed the issue with the blank screen. Very much appreciate your input.

THANK YOU! I could probably say this 1000 times. I must have turned off mine when I was cleaning the console

Thank you my man! This worked for me!

Blank screen resolved by pressing and hold the CD eject!! Thank you, nothing else worked GLC 220 2019

I had the same issue. Command screen goes black totally for no reason and sometimes it came back after 10min. Usually it happen when I start the car in the morning or after many hours without starting the car. It’s frustrating cos media is not working and the reverse camera also doesn’t turn on. Anyone know what’s the issue?

Thank you so much Victor,
Yes, that worked on my 2017 GLC300, same scenario (1st black out 4 months ago - car over 7 yrs old !) MB service keep saying I got to get new battery I am trying see if they will diagnose / update software on my extended warranty ... F.

I created this account to say thank you so much. Your post helped me a lot. My car is working now and display is perfect 👌

I've been reading these posts because my 2018 GLC 300 exhibited the flickering screen issue. I could hear the radio and blindly change stations. 360 camera was not working either. I tried the power button several times, shutting the engine off and opening the door, which also powers off Command. No result. I had a similar issue with my 2012 C300, but only once in the 7 years I owned it. They both rebooted after the car was off for a few minutes. My 2018 is still under 90 day used car warranty. I did not purchase an extended plan because having done so for the 2012, I never needed it; $6000 wasted. However, now that I know this screen issue seems to be widespread, I'm rethinking the extended warranty. It kinda makes me wonder if I should have invested in a new vehicle of a different make, like Hyundai or Infinity, both of which I've owned before for a longer warranty and no such issue. But I do love how my Mercedes drive and their comfort. I'll see what the dealer says tomorrow about a resolution. I'm also glad I financed a small part of this purchase through my bank instead of a cash purchase. Perhaps they can offer pressure toward a resolution under the current warranty.

Here's my beef. I spent nearly $60k for my wife's GLC300 thinking "It's a M-B. It's got to be great! Right? While she's now had it a few years and just turned a whopping 36,000 miles, we've experienced issues that would keep me from ever buying another one. Had to replace a silly vacuum sensor. Part cost $200, labor cost $1200 cuz they had to pull the motor to get to the sensor. German engineering??? This stupid black screen on the command center! They say " Just bring it in" instead of " yeah, we hear that alot. Did you try the power button on the console"? Bye bye Mercedes! Will be going back to one of the premium competitors with my next purchase. I gave you a try and am totally disenchanted.

Thank you so much. My screen went black in my 2017 GLC 300. I tried pressing everything. I read your post and held the eject button down and it worked. My screen came back up.

Worked for me as well. Drove the GLC300 2017 yesterday, no issues. This morning screen is black, radio and ac worked but no feeback on screen and backup camera not working. After i read this post, held the ejct button for longer than i expected and saw navigation reboot on screen. This forum saved my day!

Hi All
Yesterday my command screen went black in my 2018 GLC300. All the functions seemed to be working but I couldn’t find a way to get it back on. I called the dealer immediately. The service centre response was “yes that does happen” and asked that I come in for a software upgrade. In the mean time we shut the car off and left it for about 30 minutes and the screen came back on.
When I left it today they called me an hour later and said that the software was already up to date and the cause was an intermittent short. The whole “head unit” has to be replaced which they will do in two days. Thankfully it was under warranty or the charge would have been $6000 (CAD). I’ve also had an issue with voice recognition - one minute it works perfectly and then it doesn’t recognize anything. I’ve asked about this before and received no useful response. The service rep. now said thr controller issue could be a cause for that as well.
If it happens to you I would take it in immediately- particularly if it’s under warranty. Mercedes knows this is happening and should be issuing a recall rather than waiting for cars to be out of warranty and then charging a fortune to fix it.

having the same problem. the screen goes out randomly and won't come back on. Radio, and everything else works with the screen blackout. Did you find the fix?

My 2018 GLC 300 is having the screen go out while backing up, plus the radio and screen goes on and off regularly. I do push the power button, and the radio and screen turns back on. I am disgusted by this but I am not willing to pay $6000 to have it afterwards possibly work or not. I figure it is annoying, but not a major vehicle issue that affects the drivability. I actually wonder if my power button got something spilled on it, because it seems sticky. I am going to try cleaning that and see if it helps. I am glad to hear this is not an issue just with my car, but MB really needs to do a recall because they know the cars have this issue.

Hello everyone. I had a problem with my 2016 GLC command screen as well. There were times of which i started the car engine and the command screen went black. No buttons were working apart from the air condition. I tried to switch off the car engine and turn back on with no response. I also tried to push the off button, even hold it for some time, again with no response. The command screen recovers after some time on its own. I took the car to the official Mercendes car service in my home country and they just reboot the electronics and told me hopefully the error will not return. If it returns i will have to change the radio console which is approx. 1800euro. And i was wondering.. is it reasonable after four years the car to have such a problem? Is anybody else having a similar problem? Does anybody found a solution to the problem? Thank you

I have a 2019 GLC 300-great car but my command screen went black.
It is $1000 for the diagnostic, passenger front seat removal to get to the wiring and remove dashboard to get to control panel. 5K to fix the panel if it goes that far. Not sure what to think as this is supposedly rare.
