as possible

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. 

Blue

Red

Green

5.  Move the defl ection yoke forward, and adjust so that the entire screen 

becomes green.

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.

•  Remove all magnets, wedges, and permalogy strips.
• Confi rm data in service mode to match with CRT screen size.
  •  Set 2170D-1 to their default settings.
  •  VCEN 19
  •  VPIN  15
  •  HTPZ 15
 • Set 2170D-2 to their default settings.
  •  PPHA 21
  •  VANG 31
  •  LANG 31
  •  VBOW 31
  •  LBOW 31
 • Set 2170D-4 to their default settings.
  •  CXA8070 to their default settings.
•  Set all user compensations to their default settings.
•  Set landings to their default settings.

NOTE: Do not use the hand degausser; it magnetizes the CRT .

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:

VIDEO MODE:  STANDARD (RESET)

Perform the adjustments in order as follows:
 

1.  Beam Landing

 

2.  Convergence

 

3.  Focus

 

4.  Screen (G2)

 

5.  White Balance

Test Equipment Required:
 

1.  Color Bar Pattern Generator

 

2.  Degausser

 

3.  DC Power Supply

 

4.  Digital Multimeter

6.  Switch over the raster signal to red and blue and confi rm the 

condition.

7.  When the position of the defl ection yoke is determined, tighten it with 

the defl ection yoke mounting screw.

8.  Move the yoke up and down and/or side to side to fi nd the best 

geometry. Once the best position is confi rmed mount the rubber 
wedges to hold the yoke position in place for best geometry.

9.  If landing at the corner is not right, adjust it by using the disk 

magnets.

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 CX 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.

Preparation:
•  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.

•  For all 16X9 CRT, adjust VPIN data in normal mode for straightness 

of horizontal line.

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.

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).

1.  Adjust XCV core to balance X axis.
2.  Adjust the vertical red and blue convergence with V.TILT (TLV VR).
  Note: Perform adjustments while tracking Item 1.
  Note: When static convergence adjustments are complete, restore 

dynamic convergence.

Preparation:
•  Input a cross hatch pattern signal.

1. Affi x a permalloy assembly corresponding to the misconverged areas.
