How do I fix the MMI screen on my Audi A5?

My MMI screen on my Audi A5 has stopped working. It's not responding to touch or button inputs. What can I do to fix this issue?

First, try restarting your MMI system by holding down the power button for 10 seconds. If that doesn't work, check the connections on the back of the screen to make sure they are secure. If the issue persists, it may be a hardware problem and you may need to take it to a professional for repair or replacement.
