I've been trying to calibrate my XBR-52HX909 and feel that It should be possible to get better results than I am getting. I've looked at the options in the service menu, but it does not appear there is anything available in it other than NTSC/PAL options and some other settings that are not terribly useful (for calibration). I didn't see anything that looked like I could change color settings. I was going to order the service manual before making any changes, but I don't think it's worth looking into as there don't appear to be any useful options. Can anyone confirm that this is the case? Or are there other hidden menu options that I'm missing?
