You should be able to see if G is ground just by what it is
connected to and the trace routing. Usually, the ground is
connected to the outside case so it you get zero resistance
between G and the case, that should be that.

If it is AC input, it really won't matter which goes where. If
it has a switch on it, generally the black wire coming from the
wall socket is switched and the white is common. Again, the
white should be the N or neutral, and L the black or Live. But
just in case, see if the L goes thru the switch (if any) and that
should say something.
