SAMSUNG HLP - 4663WX - HOW TO ADJUST CCA - DLP PROJECTION TV - ACTUATOR GAIN - INDEX DELAY
CCA ADJUSTMENT
CCA Adjustment is needed after changing a light engine or digital board. In DLP TV, even the same RGB color may differ depending on the 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 Engine's color coordinates is presented on the CCA label. Input the label values to perform CCA color correction.
Condition of the CCA Label upon Receipt of the Service Engine.
"CCA LABEL" describes the measured color coordinates on the light engine.
CCA Service Procedure
To
execute CCA adjustment , perform the following steps:
- Turn off the power to make the SET STAND-BY mode.
- In order to enter the Service Mode, Press {"Mute" à"1” à"8" à"2" à"POWER"} button on the Remote Control.
- Select FACTORY > SERVICE > CCA mode on the SET.
- Switch the CCA OFF.
- Input the CCA basic engine data to the SET.
- Input the D-White -x, y values in the coordinates per destination. (if necessary)
- Select WB SPREAD, then press Enter to activate the WB Spread SET ensuring that you adjust until you get the OK sign. After adjusting, exit Factory Mode.
- When the adjustment is complete, check the picture quality.

## Attention:
Performing CCA is independent on current display's resolution and input
signal type if you don't measure color coordinates data.
Measuring color coordinates data requires specific
equipment not possessed by service personnel, what makes performing manual adjustment
impossible. Adjusting CCA is applied to all the signal mode. Don't change
Desired value because it will be harmful to the color of the SET.
INDEX DELAY ADJUSTMENT
- Turn off the power to make the SET STAND-BY mode.
- In order to enter the Service Mode, Press {"Mute" à"1” à"8" à"2" à"POWER"} button on the Remote Control.
- Select "Service" on the first display of the Service mode menu.
- Select the V-position for vertical positioning and H-position for horizontal positioning by using the ▲ ▼(up, down) buttons. [Do not set the V-position value to 34 or 35.] (Setting to these values will cause horizontal lines on the right side of the screen.).
ACTUATOR GAIN ADJUSTMENT
Before Adjustment:
- Turn off the power to make the SET STAND-BY mode.
- In order to enter the Service Mode, Press {"Mute" à"1” à"8" à"2" à"POWER"} button on the Remote Control.
- Select "Service" on the first display of the Service mode menu.
- Press the (Up or Down) button to move to ACTUATOR GAIN, then press ENTER to select.
Making Adjustments
- Change the actuator values to eliminate saw tooth shapes.
- To fine tune, increase the data value ensuring that you get the center between the starting and ending points of the disappearing saw tooth shape.
