I've had my Sony 36" XBR450 for over a year, and I love it. I've calibrated it to the best of my ability with Avia, and I'm very happy with the picure. There are a couple of problems, though. When using a calibration disc, like Avia, VE, or Sound & Vision's latest offering, I notice that when I put on a test pattern containing lines, the TV seems to cut off 1/4th of an inch on the left side. Also, the image is appears to be tilted very slightly, and no amount of adjustment of the "tilt correction" in the menu seems to fix it. Is this something a calibration expert can fix by tweaking things in the service menu? Or do I need to have the set professionally repaired?
