i'm having a sort of issue. i just wired up my saber (i picked up a saberforge hilt on ebay and wired it up using a nano biscotte, an av switch and a new led) but something's not right. when i connect the batteries, i get the bootup sound and lights around the av switch, but no sound and no led. i've no idea where something went wrong, i followed the wiring diagram and nothing. any thoughts?
