Tell you what, tit for tat.

I have a Samsung in the shop I can't figure out how to get into the
convergence section. I get into the main service menu fine.

I replaced convergence ICs in it and as expected it needs a touchup in
the Hlin parameters. You tell me how to get to the section, I will
figure it out and let you know. I suspect I didn't have quite the right
remote.

Incidentally, what parameters do you need to adjust ? If no parts were
changed, drift is usually due to yoke rotation or a slight loss of
strength of the ring magnets. These problems should be corrected at the
source rather than electronically because doing the latter will cause
the convergence outputs to draw more power.
