Quoted from finman2000:
board 29 goes to 1. Try taking the green color coded connector out of board 1 and inserting it where the green coded connector is on board 2. Essentially, you are jumpering around board 1 that could possibly be bad.
Finman2000 & LTG, thanks for your replies!
I flipped up the PF, & confirmed that board 10 lights but board 12 does not. I see the daisy chain order on the PC cover. Super handy reference!
Ergo, light board 12 is suspect.
I gave the 10->12 cable some good wiggling w/ no change.
So, I took the cable coming down from 31 (castle PF) & plugged it into 10 (order of boards in this area is 11, 9, 10, *12*, 31).
This bypasses both the #12 board & the 10->12 cable.
Back in business!!!
To confirm if it was the board or the cable that was the culprit, I put back the 10->12 cable in the 9->10 position.
Guess it's the board!
Guess I need to buy a 15-0006-00. Maybe I'll get a spare. One went bad on the original owner years ago. Compared to some light board stories I've heard, I don't feel too bad about 1 failure of the tiniest PCBs every 2-3 years.
1. Is it safe to make these swaps when the game is on? Need to first pull the power from a light PCB before messing w/ the data cables?
2. The #12 PCB seems to light "Left Winkie" or something like that. Best I can tell, the light is inside/under the castle wall? Or perhaps it has a light pipe that goes up to the castle PF? I can't even find where this light is, so part of me is tempted to not fix it, but I'll fix it anyway--it would bug me if I didn't. :]
Actually, there are quite a few GI lights in the back corners that are so well hidden that I wonder if they're even noticeable when playing.
