This displays the built-in pattern of the DDP1011 chip.
DDP1011 drives the DMD panel, so displaying this pattern
means there is no error in the DDP1011 projection function
and the panel itself.

3-4 Service Adjustment
3-4-1 Vertical / Horizontal Position Adjustment
1. Turn off the power to put the unit into the STAND-BY mode.
2. In order to enter the Service Mode, Press "Mute" "1" "8" "2" "POWER" button on the Remote Control.
3. Select "Service" on the first display of the Service mode menu.
4. 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.)
3-4-2 INDEX DELAY Adjustment
1. Turn off the power to put the unit into the STAND-BY mode.
2. In order to enter the Service Mode, Press "Mute" "1" "8" "2" "POWER" button on the Remote Control.
3. Select "Service" on the first display of the Service mode menu.
4. Press the channel (Up or Down) button to move to INDEX DELAY, then press ENTER to select.
5. The INDEX DELAY setup screen (with a red bar at the bottom of the screen) will be displayed.
6. Press the volume (Left of Right) button to check the red color at the bottom of the screen at its minimum and maximum values of
changing from red to magenta, then adjust to the mean value.

3-4-3 CCAAdjustment Service Methods : CCAAdjustment is needed after changing a light engine or digital board
CCA : 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.
1. Condition of the CCA Label upon Receipt of the Service Engine
2. CCA Service Procedures
To execute CCA adjustment , perform the following steps :
1) Turn off the power to put the unit into the STAND-BY mode.
2) In order to enter the 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 the 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 the OK sign. After adjusting, exit Factory Mode.
8) 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 per
sonnel, that makes performing manual adjustment impossible. Adjusting CCA is applied to all the signal mode.
Don't change Desired value because it will be hamful to the color of the SET.
3-4-4 ACTUATOR GAIN Adjustment Akai DLP PT50DL14X TV
1. Before Adjustment
1) Turn off the power to put the unit into the STAND-BY mode.
2) In order to enter the Service Mode, Press "Mute" "1" "8" "2" "POWER" button on the Remote Control.
3) Select "Service" on the first display of the Service mode menu.
4) Press the (Up or Down) button to move to ACTUATOR GAIN, then press ENTER to select.
2. Making Adjustments
1) As shown in the picture above, 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.
