Yesterday I tested all my wiring outside of the hilt, and had complete success in turning the saber on (foc, led, sound worked, etc).

I reassembled it in the hilt today, only to find that it wont turn on properly. When I remove the killkey, the boot sound plays as it should. When I press the av switch, the boot plays again, no other sounds, no led.

I'll be desoldering the board either tomorrow or the day after and rechecking all the wires, but thought I'd post here anyway. If anyone has had a similar issue, I thought it might help me narrow down my mistake.

Thankyou for your patience.
