HB-1A 5V regulator blown

Built the rig and got it up and running fine, then the LCD went out and all the 5V rail is dead.

Seems I have a short somewhere, don't appear to be a duff components so must be a bridge under IC 5, 8 or the DDS chip.

Nice suggestion from N1RX (Bruce)... cut the 5V rail isolating the IC/board area and find the bridge.
