Hello everyone (first time posting here)!
I just purchased the D550 and was pleasantly surprised to find this thread! It has been incredibly helpful and the calibration help is tremendously appreciated!
So I have gone ahead and changed around the settings in the service menu and have set the panel to the D7000, unlocked and adjusted the settings. Great stuff.
Strange thing is though, the touch buttons on the the set are no longer working! Not a huge deal as I use the remote 99.9% of the time, but it is peculiar nonetheless.
I can't get to the TV to check the exact firmware but last I check (3 days ago it was up to date). Also, I purchased it in California, US.
I searched fairly vigorously through the thread and I don't think I saw anything on this, but if I missed it, I apologize!
Slightly off topic, this is my first plasma and was wondering with this panel (and in general), if after the break in period you experience better PQ. Also, what break in length would you recommend?
