Maybe double check the 5v power supply polarity.
this has happend to me one other time but i dont remember what i did to fix it. if i unplug the parallel cable then the power works to the c10 but when i plug in the parallel cable lights turn off. it was working fine for a while and just started doing this out of now where and i did not mess with any wires.
thanks.

Does the C10 have a power supply jumper?
Hi carnagex
what kind of 5V power supply are you using ?
a USB cable plugged into your PC or a small wall wart mains adaptor
a good picture of the underside of your C10 would make it possible to look for
signs of a short circuit or poor solder joint
a link to the wiring diagram you followed will also be usefull
with the wires to C10 board disconnected you can test the board
using a digital multimeter to measure the resistance
across the GND and + 5V supply terminals (+5 = red & GND = black)
you should measure over 100 K ohms
with the meter set to diode test the power indicator LED should light
if supply terminals are short circuited
make a note which way round the IC's are - a photo helps
un plug them all
reconnect the supply then switch on and confirm the short has gone
switch off , then replace the IC's one at a time
switching on and retesting each time
until you have found the faulty IC or IC's
