1. Select a video input with no signal applied (the screen must be black, 

and the room must be as dark as possible.  You may use a heavy 
blanket over the screen to block out ambient light).

2. Select picture mode “Personal 1” or “Personal 2”, and set 

BRIGHTNESS to 50% and PICTURE to minimum.

3. Turn the green SCREEN control on the focus block all the way to 

the left and then gradually turn it to the right until the retrace line is 
barely visible.

4. Gradually turn the control to the left until the retrace line just 

disappears.

5. Repeat steps 1 through 4 for the red and blue CRTs.

If the jig described below is available, it is recommended that the G2 Fine 
Mode Adjustment be performed to set the screen controls to their optimal 
condition.   If desired, you can build the jig illustrated below, using 3-watt 
resistors.  Please note that if the proper voltage is not obtained with the 
listed resistor’s values, then increase or decrease one of the values in 
the resistor network to obtain the correct voltage.

1. Select VIDEO-1 mode no signal applied (the screen must be black).

2. Connect the G2 JIG.

3. Switch on the JIG.

4. Connect an oscilloscope to the TP701(KR), TP732(KG) and 

TP761(KB) of CR board, CG board and CB board.

5. Adjust red, green, and blue screen voltage to 168-172V with SCREEN 

controls on the focus block, as shown below.

1. Display a cross-hatch pattern

2. Enter the service mode.

3. Cover the red and blue CRT lenses with lens caps to allow only green 

to show (or use the method shown in the note below for turning off the 
CRTs individually without using lens caps).

4. Loosen the green CRT’s defl ection yoke set screw and align the tilt 

of the defl ection yoke so that the horizontal bars at the center of 
the cross-hatch pattern are parallel to the top and bottom edges of 
the screen. 

5. After aligning the defl ection yoke fasten it securely, making sure it is 

fully forward on the neck of the CRT.

6. The tilt of the defl ection yoke for red and blue are aligned the same 

way as the green CRT.  

  Cover the green and blue CRT lenses with lens caps (or use the 

method shown in the note below for turning off the CRTs individually 
without using lens caps), then repeat steps 4 and 5 for the red CRT.  

  Cover the green and red CRT lenses with lens caps (or use the 

method shown in the note below for turning off the CRTs individually 
without using lens caps), then repeat steps 4 and 5 for the blue CRT.

Note: If lens caps are unavailable, you can cut off the unnecessary color 
beams in the service mode by individually changing the data from “1” 
to “0” in category VPNT, item 28 RON (red), item 29 GON (green), or 
item 30 BON (blue).

2. Enter the service mode.

3. Cover the red and blue CRT lenses with lens caps to allow only green 

to show (or use the method shown in the note below for turning off the 
CRTs individually without using lens caps).

4. Turn the green focus control on the focus block to the right and set it 

to overfocus to enlarge the spot (the dot).  See fi gure at the end of 
Section 2-3 for the location of the 2-pole magnet adjusting tabs.

5. Adjust the green CRT’s 2-pole magnet so that the small bright spot is 

in the center of the large defocused spot.

6. Adjust the green focus control on the focus block and set it for the 

best focus.

7. Repeat steps 1 through 6 for the red CRT, except now you will 

cover the green and blue CRT lenses with lens caps to allow 
only red to show (or use the method shown in the note below 
 for turning off the CRTs individually without using lens caps) and you 
will adjust the red focus control on the focus block.

Note: If lens caps are unavailable, you can cut off the unnecessary color 
beams in the service mode by individually changing the data from “1” 
to “0” in category VPNT, item 28 RON (red), item 29 GON (green), or 
item 30 BON (blue).

1. Display a dot pattern (see the details of using the internal test 

patterns at the end of section 2-5, item 4).

2. Enter the service mode.

3. Cover the red and blue CRT lenses with lens caps to allow only green 

to show (or use the method shown in the note below for turning off the 
CRTs individually without using lens caps).

4. Turn the green focus control on the focus block to the left and set it to 

under-focus to enlarge the  spot.

5. Adjust the 4-pole magnet so that the enlarged spot in the center of the 

screen becomes a perfect  circle.

6. Adjust the green focus control on the focus block and set it for the best 

focus. 

7. Repeat steps 1 through 6 for the red CRT, except now you will 

cover the green and blue CRT lenses with lens caps to allow 
only red to show (or use the method shown in the note below 
 for turning off the CRTs individually without using lens caps) and you 
will adjust the red focus control on the focus block.

8. Repeat steps 1 through 6 for the blue CRT, except now cover the 

green and red CRT lenses with lens caps to allow only blue to show. 
Adjust the blue focus control on the focus block (or use the method 
shown in the note below for turning off the CRTs individually without 
using lens caps).   However, for the blue CRT do not make the 
enlarged spot a perfect circle as indicated in step 5; instead, adjust 
the 4-pole magnet so that the height of the enlarged blue spot in the 
center of the screen is approx. 1.5 times the width of the spot.

Note: If lens caps are unavailable, you can cut off the unnecessary color 
beams in the service mode by individually changing the data from “1” 
to “0” in category VPNT, item 28 RON (red), item 29 GON (green), or 
item 30 BON (blue).
