This is still an ongoing issue, and since no one seems to be able to wrap their heads around it, I'll try to cut through the confusion.
YOUR POWER HAS BEEN TURNED OFF FOR TWO YEARS.
YOUR POWER JUST GETS TURNED BACK ON FOR THE FIRST TIME IN TWO YEARS.
The FIRST thing you do is turn on the Ender 3 V2. You see the Creality logo. Then what appears in the screenshot. NO MENU. NO HEAT ON THE HOTEND. NOTHING. NADA.
THAT is the issue. Please, ask me if it's slicer settings or something.
