I've had this set for almost 3 months now and have done all the regular adjustments ....reduction of contrast, brightness and turning all 'add-on's to 'off'. Still noticing the picture is not all that great, especially the flickering black lines which become obviuos during credits roll at the end of a movie. And also due to a tight budget (just paid about $3000 in property taxes!), I don't wanna have my set professionally calibrated. I've heard some good stuff about the Avia DVD but is it really gonna clear the picture and reduce the black flickering lines on my set? Any suggestions highly appreciated.
