Black screen on raspberry pi 3b+

[renankof]

Good evening. I'm trying to install recalbox 6.1dragon and I'm getting black screen when I plug the sdcard. I'm using sdformatter to format sdcard and balena etcher to copy the files. I use the same method with retropie and Works fine. My raspberry is 3 B+. Thank you.

Hi,
You don't need to format your SD card. Etcher will do it. Etcher remove all partition, create new partitions and copy the files by itself.
Once it's done, you just have to put your SD card in slot and turn on.

Have you check SHA1 file checksum ?
