I wonder if this thread is relevant:

Solution for disconnect and board wont start problem!

Hello all, TLDR: Clip the thru pins on the encoders JST-HX headers. It will save your headaches. I had an issue after initial assembly where my control board didn’t indicate it had power even when plugged in. Power supply was fine and some of the components got hot but it wouldn’t start up. Thinking it was a control board issue after troubleshooting I received a replacement board and i checked it before assembly and it started up just fine. After installation I plugged in the power and… Nothin…

I was thinking back to when have we had hardware issues and this came to mind.
