Mitsubishi VS60803 geometry problems

[john]

Archived from groups: alt.tv.tech.hdtv (More info?)

I know about two service menus for the Mitsu I have - menu + 2357 and menu +
2359.

I am having problems finding out about some of the advanced functions though.

My TV's geometry is off - the bottom edge is "curved" - so anything like a
banner is like a faint smile - higher at the edges and lower in the middle.
Not a straight line. Avia really shows the problems well.

I also have an appearance of "curving away" on the left and right vertical
edges. As if you took a sheet of paper and wrapped it against the curve of a
baseball bat or something - so it almost appears as if the TV is a scroll
opened up with the ends curving slightly away at the very edges.

I've gone into the menus, but haven't been able to determine what options I
can try to modify. Anything I've tried really didn't make a difference and I
cancelled out so I wouldn't screw it up more.

Is there any type of "restore geometry to default" option? Or does someone
have a source they can point me to on the web or something that lists
descriptoins of the various settings in the advanced service menus on the
Mitsubishi TV's?

Thanks for any suggestions.

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.
