Ender 3 v2 Black screen and Non-functional motors

  • Hi:

    Was happy using my E3v2 until lunch yesterday. I turned it off and later in the afternoon, when I turned it back on, the display would not come on. Back light is on, fans are running, but nothing on the display.

    Googling and watching videos and reading threads here to try and figure out what went wrong and what is the fix.

    Tried downloading various firmwares and DWIN_SET files, flashing both the mainboard and the display. Got the display to work for a little while, but then the motors will not run, (autohome will not move print head).

    I've tried submitting a ticket at support, but they only responded with a request for a screen shot of my receipt and a video of the problem.

    This seems to be a common problem for people. Unfortunately, the forum advice is very fragmented and hard to piece together. Does anyone have a comprehensive doc on how to get my E3v2 to work again? Very disappointing to experience these failures when I only printed about 10 items on it.

    Thanks in advance for any help,
