Well, bad news. I de-soldered the main LED wires, cleaned the pads, and then touched the wires to the pads while the saber was off. The Red and Green pads have power, only the Blue pad was not being driven.
It looks to be a bad driver. What is the prognosis? Is a bad driver (or two bad drivers) repairable, or is the board "toast" (pun intended, lol)? If the board is finished, I will likely purchase a Crystal Focus X; they cost less than what I paid for the Crystal Shard
On a happier note, I was able to take the components and build my third Pico Crumble lightsaber (Light Sound!). So, not a total loss.
