I just moved; unplugged everything hooked up to my UN656001FXZA, moved it to the new location, and plugged it all back in (it was unplugged for maybe a day). For some reason the picture/calibration settings must have reset b/c they changed. I am not sure if they are back at the factory settings it started with b/c I don't remember those, I just know they weren't at what I had changed them to and had been using for the last 6 months before this move (luckily I saved these in an excel spreadsheet so I could switch them back easily after this).
I am mainly curious why this happened; no one was around to change them but me so it wasn't done manually. Does anyone know, does unplugging the power cord from the back of this unit for an extended amount of time reset the picture settings? I am using the same HDMI inputs, don't know what else it may have been.
