Quick bit of info. I was just on the phone with Panasonic Netherlands enquiring about the DSE on my tv. They acknowledged it was a fault, but then they asked if it had been calibrated. It was a good thing I didn't according to the Panasonic employee because that would have void the warranty. I even asked if I could do it being ISF certified. She was sure it would void warranty unless done by an official panasonic support centre. I told her I could not believe that and asked her to go check it out again. She told me she would and would get back to me. As soon as I receive an updated answer I will post it here. But I would recommend to call your local Panasonic office to be sure.
