Preparation:
•  Use cross hatch signal to rough adjust focus, G2 and then input a 

white pattern signal.

•  Face the picture tube in an East or West direction to reduce the 

infl uence of geomagnetism.

•  CXA2170-D4 Confi rm Focus data - See 2.4.1 Dynamic Focus/

Dynamic Quadrapole Data Table 1.

•  CXA8070 (Should be set to default) - or unplug CN1 from DY.

 

CXA8070 default (initial) data: (See 4-4. SERVICE DATA for the 
default data values for YBWU, YBWL, RSAP, RUBW, RUMB, RLBW, 
RLMB1, LSAP, LUBW, LUMB, LLBW, LLMB, CADJ, HVCA for each 
model)

•  CXA2170-D1, -D2 table default (initial) data: (See 4-4. SERVICE 

DATA for the default data values for VCEN, VPIN, HTPZ, HCNT, 
PPHA, VANG, VBOW, LBOW LANG for each model)

1.  Input white pattern from pattern generator.  Set the PICTURE control 

to maximum, and the BRIGHTNESS control to standard.

2.  Loosen the defl ection yoke mounting screw, and set  the purity 

control to the center as shown below:

Purity Control

3.  Input a green pattern from the pattern generator.

4.  Move the defl ection yoke backwards, (See Figure 1) and adjust with 

the purity control so that green is in the center and red and blue are 
even on both sides. 

The following adjustments should be made when a complete 
realignment is required or a new picture tube is installed. 

These adjustments should be performed with rated power supply 
voltage unless otherwise noted.

The controls and switch should be set as follows unless otherwise 
noted:

•  For all 4x3 CRT, VPIN data has separate register for full and 

 

V-compress. Adjust both modes if needed.

•  For all 16x9 CRT’s, adjust VPIN in normal mode for straightness of 

horizontal line.

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.

Preparation:
•  Set the CONTRAST and BRIGHTNESS control to standard (reset).

•  Input a cross hatch pattern signal.

1.  Set dynamic convergence to default values (as in 2-1 Beam Landing) 

or disconnect the dynamic convergence before adjusting static 
convergence (CN903), except for minor touch-up.

2.  Adjust H.STAT convergence, RV9001, on CH Board to converge 

 

red, green, and blue dots in the center of the screen.

3.  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).

Normally, no adjustments are necessary for these systems. If for some 
reason the data is lost, use the data from Table 1 below:

1. 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. 
  Note: 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. 
  CAUTION: Be sure that Neck Assembly is in the proper location.    
  Mark position before moving or replacing neck assembly.

Procedure to adjust or check:

1. Short Q8018 B-Gnd to disable DF. B Mark is on the circuit board.    
  Circuit connection changes should always be done with the power off.  
  CAUTION: Q8018 heatsink is live and peak voltage is 250V.
2. Input a cross hatch signal.
3. Change CXA2170-P2 item 2 RGBS to 2 to make green only.
  1. Overfocus to adjust DQP phase. Adjust the data  

 

 

    (CXA2170-D4 item 8) to balance left and right vertical line width.
  2. Once DQP is balanced, remove the short from DF circuit and  

 

    refocus the set.
  3. Adjust DF (CXA2170-D4 item 7) to balance left and right vertical    
 line 

width.

  4. Reconfi rm focus performance.
