I'd suggest checking on the connection state of the small diode inbetween the SOT23 transistors to the left of the LED
Finally got around to poking at things - that was indeed it, saves some hunting
Was going for an angle view (

Should be a simple fix with a touch of flux and a heat gun
That diode is one of the hardest parts for the machine to place correctly because it's such a friggin' small package, smaller even than the 0603. It's the littles thing on the board.
Indeed - That text at the top is the tiny "GekkoScience" silkscreen. The smallest I personally ever work with is 0402, which is plenty tiny and uncomfortable enough, and yet far from the smallest passives found in modern mobile devices.
Thanks for the picture.
I have one that just start acting up, it just started hashing slower and slower until it stopped and with the pic I found the same leg had come up just enough. Just to check it, I pushed that leg down and it started hashing again.
Got the stick pulled out right now and going to touch it with the iron just enough to flow the solder (after work, if the tip is small enough to get in there).
