On my CFTBL, I noticed that on the backbox insert, the string of GI (555) bulbs under BLACK LAGOON do not illuminate.

The C-R-E-A-T-U-R-E string works and when I do a GI test, all 6 strings show some sign of life.

Guess the question is, for the string in the insert behind BLACK LAGOON, what string are these supposed to be part of ? Seems like there's power at J120 and J121.
Kind of wondering how that can be.

Anyone seen this before?

I can see the wires and it's just odd because all six GI strings have power during test.
If you look in the back box for Creature,
You have the top row of bulbs that are NOT GI that spell C R E A T U R E
The 555 bulbs below that row are the ones I'm talking about.
Seems like they are part of GI string 3 but I see GI 3 light up on the play field during test.
It's like it's just the GI String 3 on the back box.

Would a bad xtransitor cause this? Must be something like that.
