SAMSUNG - HLR SERIES DLP TVs CCA Adjustment Service Methods


                        Samsung HLR Series DLPs


CCA:  In DLP TV, even the same RGB color may differ depending on Light Engine.  CCA (Color Coordinate Adjustment) corrects the color to achieve the color accuracy.  CCA performs color correction after measuring 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 on Service Engines' color coordinates is presented on a CCA label.  Input the label values to perform CCA color correction.

CCA Service Procedures

  1. Turn Off the Power to put the unit into Standby Mode.
  2. In order to Enter Service Mode press [Mute => 1 => 8 => 2 => Power] button on the remote control.
  3. From the Factory Service Mode Menu, select "Service > CCA"
  4. Switch the 'CCA' Off.
  5. Enter the CCA Red, Green, Blue and White basic engine data to the DLP.
  6. Input D-White-x, y values in the coordinates per destination, if necessary.
  7. Select "WB Spread", then press 'Enter' to activate the WB Spread Set ensuring that you adjust until you get OK sign.  After adjusting, Exit Factory Mode.
  8. When adjustment is complete, check the picture quality.
#  Performing CCA is independent on current displays' resolution and input signal type if you don't measure color coordinates data.  Measuring color coordinate data requires specific equipment not possessed by service personal, that makes performing manual adjustments impossible.  Adjusting CCA is applied to all the signal mode.  Don't change desired value, because it will be harmfull to the color of the set.
