In adjusting my Panasonic 47" HDTV, I've come across some bothersome issues. I'd like to know if these are common across most HDTV units, or if this is something specific to my specific TV. First of all, I've been using the AVIA calibration DVD to set the service mode registers for proper blue scale and tint, and for getting the red, blue, and green at 0% on the color decoder chart. Even after doing this, I still notice quite a bit of "red push". Is it possible to have both the color/saturation AND the decoder chart to look perfect, but STILL have significant "red push"? The only solution is to lower the color and desaturate the green's and blues to further limit the red push. Second, I notice quite a difference between using the service mode CUT_OFF to show just the red, green, or blue guns as opposed to using the supplied gel filters that came with the Avia DVD. I assume the CUT_OFF is far more accurate, so I've been using that instead of the filters. Am I wrong? Finally, I calibrate the TV using the S-video input of my DVD player so that my satellite s-video input uses the same settings. But when I switch to the component input of the DVD player, I need to boost the color by more than 20% to get the blue/tint and color decoder charts back on line! Is it typical for component inputs to desaturate the colors more than s-video? Thanks.
