Hey Marcone-
I've come across a similar issue just yesterday, which I should get sorted out today. My "Cut" switch for the large fader does not illuminate when I press it, but when I solo other channels, it DOES.
My console is an E series, so when you "Cut" it actually defeats the line input to the channel, sometimes this scares me cause I think the channel is dead when I don't see the line input LED haha.
That said, I'm pretty sure the problem is some sort of logic problem coming from the "Cut" switch and telling the bulb/LED to illuminate, but I'm not as good as Bruce, so don't quote me... I just got some logic switches in yesterday so I will be probing.
If anyone else has input, love to hear it!
Also, let me know about those 242 cards
