Recently calibrated a TH50PZ80U, be careful of taking measurements in the service menu. Other than the fact that it defaults to vivid and you have to change it to cinema all the time, I noticed things look different in the servuce menu. Be careful taking measurments in the service menu, I didn’t get the same readings out of it as I did in. Verify the work outside the menu which is a pain since you have to turn it off to exit the menu.
