A blown diode is likely to take other components with it as these diodes are to protect the transistors on the board. I've now reconditioned four modules, and all are the second generation board where the relays and capacitors are the other way around, and all had a blown power supply protection diode. Here's a photo of the work I did to my own board http://www.delorean.co.uk/pictures/DCP02364.JPG I have designed a replacement circuit but haven't built it yet.
