IIRC, Color Sentry changes the color/tint and other controls to another set of servicer adjusted controls - kind of a "get it back to normal, should the kids mess with it" kinda thing. Most have concentric controls - where you can run a 1/8" shaft straight slot screwdriver into the hollow shaft of the control to access the Color Sentry controls. Some also have the photocell that brightens/darkens the pic when the room lighting is adjusted - that comes on when Color Sentry is on.
Just about every manufacturer did it that way - Motorola had the "Instamatic" button, RCA had the "ACC" or AccuColor" button.....
