I have mypicture set up to my liking. Sometimes when I change the source of the program the picture colour becomes distinctly more saturated. If I then go into the Picture settings in the Action Menu and adjust the colour either up from say 60 to 61 or down from 60 to 59 the picture reverts to normal.Only one point either way is enough for it to reset. IIt is annoying that I have to reset the picture each time.
Could it be because the Store Demonstration Mode is enabled?
Check it in Settings (don't remember where exactly, search) and disable it.
