My TV is a Hitachi, and the Magic Focus button is pretty good, but it was never as good as what I could do by hand with the Electrohome projector we had installed in our auditorium when I was in grad school.

If you look at the Hitachi forum, it looks like I may have to replace several chips and/or resistors on the control board. It's $50 in parts, but whenever I touch a soldering iron, I have a habit of destroying anything I work on. On the other hand, paying somebody to do it would probably cost me $500+.

*sigh*
