Set up process not starting
I recently finished assembly of my i3MK3 printer. When I plugged it in and turned it on, I got the language menu and selected English. Nothing happened. Finally, after several button presses, it accepted my choice and move to the next question... "Hello, I am your original Prusa i3 printer. Would you like me to guide you through the set up process?". I have selected both the "yes" and "no", many times apiece, but it just keeps going back to the same previous question. I've turned the printer on and off several times, but to no avail. I'm not sure how to proceed. I've attached 3 pictures. The first two are pictures of the question that the screen keeps going back to. The last picture is what it displays after I select "yes" or "no". When I select "yes" or "no", the fan turns on and the message in the third picture appears for a few seconds, and then it just returns to the message in pictures 1 and 2. Any advice would be greatly appreciated. 
RE: Set up process not starting
How exactly are you pressing yes ? Its a really common mistake for people to push the X button thinking that is enter, when it fact its reset the entire printer. Pushing down on the rotary select is enter. If that's what you were doing then apologies.
