I have a Sony KP-41T35 RPTV that is badly out of focus and/or misconverged on the corners. I can only do a center convergence with the user menus. I bought it from Circuit City and my service contract is up in November so I am having them come out and see if they can focus it but my experience with there techs isn't good for this sort of thing. I would like to have it ISF calibrated. Can't find anyone in Phoenix that is willing to do it.
