It lookslike you have your 5 volt line wrong! What does the yellow markings on the green wire signify??? Na if that is conncted to the 5 volts it's OK. IT's hard to say from the pictures what about checkin the basics starting with the seating of the main chip of the DBU! Then double check all solder joints i use connectors for all board mounted wires, but if that is all you have, just seat them better, ohm them out, and go from the there!
