Not being familiar with the FZS, and not having a diagram, I'd assume the clock unit takes a 12V feed, and any lower voltage supply rails will be generated within the clock unit itself via a regulator on the PCB.
LED's seldom fail (as stated by someone else, they don't respond well to "normal" testing), maybe you're seeing a problem that isn't there?
