I have the service manual for my Toshiba 32A40 (actually it says 32A50 on the manual but same TV I guess). Anyway, I'm just wondering what the difference is between the "Service" mode and the "Design" mode, and which one I should use when calibrating the setting using AVIA. When I first got the TV I calibrated using the regular user menus, but now that I have a chance to sit down and do it right I want to set all those menus to the center and make the adjustments in the service menu. I'm just not sure what the difference is between the service menu and the design menu and which I should be using. Thanks guys.
