Hey team

Hey team! I don’t know what’s going on with my Skoda Octavia but 2010. Just recently bought it. I was driving on the way home from work, I was listening to song and suddenly my screen started off automatically and it’s making weird sound like “boom” repeating. I even tried turn off the car and still making sound. Any idea why is like that and it’s fixable by my own?
Thank you for advice👍
