I *think* that you are referring to the LEDs located above 

D21, D31, 
D32, D42, 
D43, D53, 
D54, D64, 
D65, and D16.
These LEDs are all connected to signal line LED7.  Check that resistor R7 is installed and is soldered correctly. Check that vertical jumper LED7 is soldered correctly.
If things are still not working, carefully check the pins of the microcontroller, and make sure that each pin is soldered neatly and that there are no excessively “blobby” connections there.
