Here's the "B" line service menu info:

www.talonix.com/images/Servicing.pdf
They explain in great detail all of the parameters for adjusting "B" line sets. You kinda have to use both for Service Menu adjustments.
BTW, I have a couple of Gigs of Zenith/LG/Goldstar service info, all mirrored from their site if you need anything else.
Hope this helps
Cheers,
