I have the 65819. It was calibrated by Chuck Williams (DC). I love the picture. My rant is on the user controls. If the set loses power, it defaults all settings to the factory levels. This is for each input. Fortunately, the calibration settings zero out most of the slider bars. However, color temp is turned to high and contrast is turned all the way up. You have to go through each input to correct. IMO the set should remember the settings prior to the power failure and keep those settings. In addition, when the temp and contrast are changed in service menu, those changes should become factory settings (in reality, I accidentally hit the video reset button on the TV more often than having a power failure). On day, I will program a macro for my remote to correct contrast and temp for all inputs. Do other sets have this annoying feature?
