Power & Source of Big Ideas

I've tried other display devices, my issue persists.

I was wondering, what noticeable differences (if any) are there between the NanoPi-S2 versions 1609 and 1710? A quick google search presented no change log and I didn't see a log on the site.

Thanks in advance,
I too am experiencing this issue, however for me the green light flashed once, briefly and not again. I have tried flashing an SD card as well as an eMMC (and yes, is connected correctly).
