CCA (Color Coordinate Adjustment) SERVICE MODE AFTER LIGHT ENGINE REPLACEMENT TO SAMSUNG HLP 5663W DLP PROJECTION TV
CCA adjustment is needed after changing light engine or digital board.
In DLP TV, even the same RGB color may different depending on the light engine. CCA corrects the color to achieve the color accuracy. CCA performs color correction after measurements and inputting the current light engine's data on actual color coordinates for displayed RED, Green, Blue and white color patterns, using a color coordinate measuring equipment. At this moment color correction is performed on the basis of previously inputted Desired Color Coordinates and Measured Color Coordinates. Measured data of service engine's color coordinate is presented on the CCA label. Input the label values to perform CCA color correction. [The condition of CCA will be on the CCA label upon receipt of the service engine]
