•  Input a cross hatch pattern signal.
•  Set Video Mode to: Standard (Reset)
•  For all 4X3 CRT, VPIN data has separate register for full and V-

compress. Adjust both modes if needed.

1.  Adjust service mode CXA2170D-1 05 V-CEN so that the top pin and 

bottom pin are symmetrical from top to bottom.

2.  Adjust service mode CXA2170D-1 06 V-PIN so that the top pin and 

bottom pin are symmetrical from top to bottom.

3.  Horizontal lines should be straight from left to right.  Check landing for 

side effect.

•  Set the CONTRAST and BRIGHTNESS control to standard (reset).
•  Input a cross hatch pattern signal.

1.  Disconnect the dynamic convergence before adjusting static 

convergence (CN903), except for minor touch-up.

2.  Adjust H.STAT convergence, RV9001, to converge red, green, and 

blue dots in the center of the screen.

3.  Connect dynamic convergence back. 
4.  Adjust V. STAT magnet to converge red, green and blue dots in the 

center of the screen.

The respective dot positions result from moving each magnet interact.  

Perform the following adjustments while tracking.

1.  Use the BMC tabs to adjust the red, green and blue dots so that 

they line up at the center of the screen (move the dots in a horizontal 

direction).

2.  Adjust the vertical red and blue convergence with V.TILT (TLV VR).
 

Note: Perform adjustments while tracking Item 1.

•  Input a cross hatch pattern signal.

1.  Affix a permalloy assembly corresponding to the misconverged areas.

•  Set dynamic convergence using the following service mode adjustment 

data.

•  Only H-component can be corrected, for vertical component use 

permalloy to compensate.

•  After adjusting the following parameter, write data into NVM 

MUTING  +  ENTER  then copy for 1080i CPY2

Confirm neck assembly Z axis position. (See Figure 1)
1.  Input a dot signal.
2.  Set Video Mode to STANDARD.
3.  Adjust focus VR clockwise (DE-Focus) to confirm that the dot’s shape 

is centered. (Figure 2 & 3) Confirm neck assembly rotation by W Board 

position. W Board should be level ±1º. Adjust as necessary to balance 

dot shape along center horizontal line, then refocus.

4.  Input a HD monoscope signal.
5.  Confirm center focus with focus VR.

DOT SHAPE:

NOTE: Changing neck assembly position will affect corner convergence.

Normally, no adjustments are necessary for these systems. If for some 

reason the data is lost, use the following data:

Write the data from any non-vertically compressed mode, then use the 

CPY1 function (CXA2170D-4 Item 6) to copy the data to the vertical 

compressed modes. V-compressed data is identical to non-v-compressed 

data. Service personnel with a trained eye can adjust the DF or DQP 

registers to adjust DF phase (Item 7) or DQP phase (Item 8), respectively, 

to balance left and right focus. Refrain from adjusting more than 5 steps 

from table data below. Further adjustment indicates a circuit problem 

-- troubleshoot to cause. Be sure that Neck Assembly is in the proper 

location
