John, the degree of precision that you are trying to achieve is likely to
require a tech who is intimately familiar with convergence, with the
Mitsubishi menus, and with the interactions between adjustments at the edges
of these sets. Unfortunately, they were sometimes not straightforward
because some adjustments limited the range of others. It would be unlikely
that you could be given the proper instructions without some hands-on
tutoring. Lots of good techs can't get it right. I'd suggest you get a
copy of the manual if you really want to tackle it, but even then you will
likely not be able to sort out the needed adjustments.
