ISF video calibrator and all-around good guy, Gregg Loewen, came by last night and performed his magic on my "old fashioned" Panasonic PT56HX41P (56" 4:3 HDTV).
Like many before me, my account of the evening's results is very positive and Gregg gets 2 mighty thumbs up from me.
Even fellow HTFer, Leo, showed up to take a gander at the calibration-fest.
---------
Just a cursory overview of the night's activities:
Removed screen guard (to get rid of the glare) and this definitely made the image look less distracting due to previous reflections.
Lined inside of the cabinet with black cloth to cut down any internal reflections.
Manual adjustment of focusing of the lenses and associated electronics.
Grayscale adjustment was done. Originally, my grayscale was all over the place, but afterwards, it was much more uniformily even around 6500 K. This simply can't be done by eye, and it lays the foundation for the rest of the calibration.
Color calibration was next on the list. This evened out my problem with a reddish-ness to the overall picture of my set previously. It's not quite a red-push problem.
Geometry/overscan was addressed.
Convergence was the main last task, and it's pretty time-consuming, but the results add to the overall improved picture quality.
And along each step, Gregg was very good in covering the details of what was being adjusted and how it would impact video performance/quality.

Whatever my recommendation is worth, if Gregg's coming through your town, and you have a set that's in need of calibration, you can't go wrong with having Gregg work on it.
