LED Calibration Test
Periodically, the LED-based televisions will conduct a calibration test to ensure brightness and color consistency in the
picture. When the power button is turned off on the television, the television will display (in full screen) a sequence of
cyan, magenta, and yellow before finally turning off. The television displays these colors and makes any adjustments
necessary to ensure the quality of the picture. This is a normal cycle for this television.
