It sounds like you have followed the instructions in the video closely, but are encountering a black screen issue during the main board update on your Ender 3. Here are a few troubleshooting steps you can try:

  1. Make sure your SD card is formatted to FAT32 and is properly inserted into the printer.
  2. Double-check the firmware file on the SD card to ensure it is named correctly and located in the root directory.
  3. Check if the power supply to the printer is stable and sufficient for the update process.
  4. Verify that the connections between the main board and the display are secure and properly seated.

If you have tried these steps and are still facing the black screen issue, I recommend reaching out to the community forums for Ender 3 users or contacting the manufacturer for further assistance. Good luck with resolving the problem!
