Identify inductor color code - green on 3rd position?
Just by looking at it's physical size, it is probably 4.7 &micro;H.  If that is true, then the base unit would be pH.  I guess that's what the manufacturer picked for this inductor series.

However, before you replace the inductor, re-solder the top joint.  That's clearly a bad solder joint, at least on this side of the board.  It may have been marginal all along, then finally went open.  If so, you don't need a new inductor.
