[quote=AZREOSpecialist;21155815There was an issue in the original 60" firmware that caused some strange dimming behavior when switching picture modes that was resolved in a later firmware release. The affected users noted that once they power cycled the set, the problem disappeared.
Airgas and I were constantly harping on that back then. You'd change the picture settings (e.g. THX to non-THX, to Pure) and then all of a sudden the picture would dim about 80% and not restore until you either cycled the TV on & off or went back in to the picture settings and started cycling those again.
As you said, the software release fixed that immediately. However this pulsing issue is different and I don't think dependent on the act of changing settings. If I leave the TV in non-THX mode and power cycle, I'll still get the pulsing regardless.
If I have it in THX mode and start changing picture settings, but return to THX mode, I'll never see the pulsing. For me at least it's THX mode without the issue and non-THX movie mode with the issue. Again, even then it's not something that's seen very often.
