hey guys, i'm trying to get into the advanced service menu's for my panasonic PT-53WX53 53-Inch Widescreen HD-Ready Projection TV. I had a service guy come by once to fix a warranty related issue, and he did an AWESOME calibration/convergence of the guns by pressing a series of buttons on the front panel... I would like to try to do the advanced convergence as its been a few years now. Thanks!
