So I just got my Ender 3 v2 today and I'm beyond excited. I set up the printer and then tried to run the Auto-Home, when it did this it made a strange sound as it was trying to move and then just stopped moving. I waited some time and saw people had similar issues here: https://forum.creality.com/topic/190/ender-3-v2-stuck-on-autohome-motors-unresponsive
So one of the recommendations was to reset the firmware. I tried to do that from the above link but when I insert the card and turn on the machine (through the switch) the display just doesn't show anything. I know the display is on as it's backlit, but unlike the videos I've found online where the display is dark for ~10 seconds and then boots up, mine never seems to boot up.
