With Pioneer TV's you must remember that you need to do the "stanadard" setting first as all others are "Offsets" from this one. If you do 1080i or comp 480p and then do standard, everything will shift. Aslo remember to reset or "Zero" the user settings befor doing anything, so that when you look at the pre-post service mode there won't be a huge difference (exiting the service mode resets the user settings).
