After a calibration, the majic focus lines on my Hitachi 57SWX20b were very broad, and the vertical red lines are in fact dots within larger green dots. The calibrator thought it may have been a setting that was changed, but I've been unable to find it. I can still do a manual focus with an Avia disk, but it's a lot more difficult and I can't get it as good as I used to. Any ideas how to get this back to the crisp lines the majic focus used to have?

you need to replace both STK392-120 Convergence Ics. You can get replacement Ics at the following link and they provide free installation instructions so you can do the repair your self. Heres the link http://servicemanuals.vstore.ca/
I'm trying to fix the issue on my 43FDX20B. So far, I'm able to move the lines up and down, but can't get the left/right motion to fix it. The attached link has the dynamic mode instructions, so you can correct this issue yourself.
The only thing I didn't have was the screen overlay jig the manual talks about. I decided to create one myself and use the screen as a beginning template. I went to our local hardware store and picked up some home window weather covering. The roll cost about $15, is a clear strong plastic and the template was very easy to create. I used a straight edge after I put dots on the plastic and measured the lines for being square and equal after I took it off my tv. Good thing is that if you don't like what you make the first time, you have a 25' roll to use to try again (ha).
Yes it certainly sounds like you have the old convergence outpuyt IC's that have gone bad in this TV set. If you have the soldering skills, and know how to work on printed circuit boards, you can repolace both of the STK convergence IC's. If you do not, you can get the complete convergence board at http://www.ptscorp.com, and the Hitachi board number is JT22056. Good Luck
