1. Receive the Monoscope signal..
2. Set BRIGHTNESS to 50% and PICTURE to minimum.
3. Turn the red VR 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 disappears.

FOCUS Block

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. SW on JIG.
4. Connect an oscilloscope to the TP9101(KR), TP9201(KG) and 

TP9301(KB) of CR board, CG board, and CB board.

5. Adjust red, green, and blue screen voltage to 177.5+/-0.5V with 

screen VR on the focus block.

1.  Connect the color bar generator monoscope patter to Video 1 input.
2.  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).

3.  Loosen the CRT’s deflection yoke set screw and align the tilt of the 

deflection 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. 

4.  After aligning the deflection yoke fasten it securely to the 

funnel-shaped portion (neck) of the CRT.

5.  Cover the green 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), then repeat steps 3 

and 4 for the red CRT.  

  Cover the green and red 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), then repeat steps 3 

and 4 for the blue CRT.  

Note: If lens caps are unavailable, you can cut off the unnecessary color 

beams by controlling the service mode 2170P-2 RGBS.

In this adjustment, use the remote commander while in service 

mode.  For details on the usage of the service mode and the remote 

commander, please refer to section 

2-10. ELECTRICAL ADJUSTMENTS BY REMOTE COMMANDER.

1.  Loosen the lens screw.
2.  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).

3.  Turn the green lens to adjust to the optimum focus point with the 

crosshatch signal.

4.  Tighten the lens screw.
5.  Cover the green and blue CRT lenses with the 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).

6.  Turn the red lens to adjust to the optimum focus point with the 

crosshatch signal.

7.  Tighten the lens screw.
8.  Cover the green and red CRT lenses with the lens caps to allow only 

blue to show (or use the method shown in the note below for turning 

off the CRTs individually without using lens caps).

9.  Turn the blue lens to adjust to the optimum focus point with the 

crosshatch signal.

10. Tighten the lens screw.
11.  After adjusting the items:
  2-5. FOCUS VR ADJUSTMENT, 
  2-6. 2-POLE MAGNET ADJUSTMENT, 
  2-8. 4-POLE MAGNET ADJUSTMENT, 
  reconfirm the optimum focus point and adjust again if necessary.

* In PJE mode, every time 6 is pressed, the test signal changes to: 

“crosshatch+video signal” → “crosshatch+borderline(black)” → 

”crosshatch(black)” → “dots(black)” → off

1.  Set generator to crosshatch.
2.  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).

3.  Turn the green focus VR on the focus block to adjust to the optimum 

focus point with the crosshatch signal.

4.  Cover the green and blue picture 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).

5.  Turn the red focus VR on the focus block to adjust to the optimum 

focus point with the crosshatch signal.

6.  Cover the green and red picture lenses with lens caps to allow only 

blue to show (or use the method shown in the note below for turning 

off the CRTs individually without using lens caps).

7.  Turn the blue focus VR on the focus block to adjust to the optimum 

focus point with the crosshatch signal.

8.   After adjusting the items:
  2-4. FOCUS LENS ADJUSTMENT, 
  2-6. 2-POLE MAGNET ADJUSTMENT, 
  2-8. 4-POLE MAGNET ADJUSTMENT, 
   reconfirm the optimum focus point and adjust again if necessary.

Note: If lens caps are unavailable, you can cut off the unnecessary color 

beams by controlling the service mode 2170P-2 1 RGBS.
