A new bulb installation would necessitate readjustment?
I don't know if "necessitate" is the right word, but I know that a professional calibrator wants the bulb to have at least 100 hours on the bulb before he does a calibration and they recommend having the TV calibrated once a year. Yes, I know there is a financial incentive for such a recommendation. However, most calibrators offer recalibrations of the same TV at a substantial discount ($400 for the first; $250 for subsequent calibrations)
I last had my TV calibrated 3 years ago, so I think having it recalibrated again would be prudent. However, I don't want to have it calibrated with an older, dimming bulb so I'll wait until I put in the new one before recalibrating.
