Samsung doesn't do field upgrades so while it's possible that a firmware revision would change some values in the SM it wouldn't have to.
If so, does that mean that the owner would have to go in and recreate all of the changes that were made during a calibration?
I had my set ISF calibrated and I recorded all the settings before and all the changes after. I thought it was a good idea. I didn't do it because I thought Samsung would change my firmware, because there is no indication that they would.
Are there any other actions that would reset the service menu or any other settings that were changed during a calibration?
The firmware is stored on the digital board. If that board fails then it would be nice to have records of what was in your SM. Any new digital board would probably
have a different firmware version but that's not certain.
I don't like the thought of paying $500 for a calibration and then losing everything when I have to change the light engine or do a firmware upgrade. Just curious. Thanks.
Changing the light engine would make some differences in what you would see. You can't change the firmware except if you need a new digital board. That's rare.
SethS said he would recalibrate at a reduced price, but that would probably depend on the circumstances.
The main reason for waiting to calibrate a new TV is to get past the early failure period.
If you were unlucky enough to need repairs that effected the SM settings that were adjusted in a calibration (it's only a select few), reentering your calibrated settings would probably get back most of your calibrated PQ.
