One trick is to make a small coil of wire and solder it to a coax. Put the other end of the coax to a spectrum analyzer. You do a raster scan across the board and find the conductors that are radiating. By raster scan, you move it in a straight lineacross the board then come back to the start and move the perpendicular direction by a coil diameter and move it across the board again.
