COMAND exterior screen removal
If so, why risk breaking something, take it to a MB dealer and let them fix the rattle ‘no charge’.
.
It has never been that much of an issue so I have not bothered to mention it to the dealer. I do tend to agree with others that if the dealer has not heard of it/there is no known "fix" then I would not have them having a crack at it on your car.
To help with your question though I suspect if you disconnect the power with the screen in the up position it will stay there and you will be able to work out what is going on.
