How to fix a malfunctioning MMI screen in an Audi A7?

My MMI screen in my Audi A7 is not responding and I cannot access any of the functionalities. How can I fix this issue?

First, try resetting the MMI system by pressing and holding the Nav, Menu, and Tones buttons simultaneously. If this does not work, check the fuse and replace it if necessary. If the issue still persists, it might be a hardware problem and you should bring your car to a certified mechanic

Check the connection of the screen to the main unit. If the connection is loose, try reattaching it. If the connection seems fine, the screen itself might be faulty and needs to be replaced. You can either bring it to a mechanic or try replacing it yourself if you have the necessary technical skills.
