Sounds right. I wonder if it's possible that the output of your disc. transformer was inadvertently wired in reverse at the factory? I'm not even sure if that would do it, but it seems odd you're getting a signal inversion to your eye tube.
I also noticed a note in Sams saying some models have L23,L24 reversed. Not sure how that would effect the alignment process.
Did you ever figure out why the sound trap(A13) was not working in the tuner? That could account for some dependencies seen during alignment.
