Shockingly Small

Latest challenge is to find the duff component on this board.

Nothing looks fried or poorly soldered, but one of the larger components on the other side is likely. It's difficult for the amateur to test things on the board because you have to consider where else the current could flow, as well as the piece you're testing.

Extra might help anyone to guess what the mystery object is. 

Thanks for hosting the tiny mystery, Jen.
