I bought a blue LED for my Anakin, the one with an Amber LED. I switched the LEDs last night and turned it on and got - as the title implies - sound, but no light. That's rather not what I wanted so I checked the LED (quick disconnect) in another saber and it works just fine. I'm assuming there's something wrong with the MR board, but it's in a piece of plastic that doesn't come apart.
Anybody have any bright ideas on how I can get it to light up?
One more bit of usefull/useless info - this saber was originally converted by Ultra, I'm told a year or so ago, all I did was put in Tim's kit and change the LED from a green to amber, and now to blue.

I guess if all else fails I've a stock Anakin that I could disassemble and steal that section from.

EDIT: It looks like I'm getting 3.2V to the quick disconnect connector, so shouldn't it be working?
