Preparation :
• Before starting this adjustment, adjust the focus, horizontal size

and vertical size.

• Receive dot/hatch signal.
• Pic mode: Personal (Pic 90%, Brightness 50%, Colour 50 %,

Hue 50%, Sharpness 50%).

1. (Moving horizontally), adjust the H.STAT control so that the

red, green and blue dots are on top of each other at the center of
the screen.

2. (Moving vertically), adjust the V.STAT magnet so that the red,

green and blue dots are on top of each other at the center of the
screen.

3. If the H.STAT variable resistor cannot bring the red, green and

blue dots together at the center of the screen, adjust the
horizontal convergence with the H.STAT variable resistor and
the V.STAT magnet in the manner given below.
(In this case, the H.STAT variable resistor and the V.STAT
magnet influence each other, so be sure to perform adjustments
while tracking.)

Y separation axis correction magnet adjustment.

1. Receive the cross-hatch signal and adjust [PICTURE] to [MIN]

and [BRIGHTNESS] to [STANDARD]  .

2. Adjust the Y separation axis correction magnet on the neck

assembly so that the horizontal lines at the top and bottom of
the screen are straight.

Note
1. The Red and Blue magnets should be equally far from the

horizontal center line.

2. Do not separate the Red and Blue magnets too far. (Less than

8 mm)

Preparation:
• Before starting this adjustment, adjust the horizontal static

convergence and the vertical static convergence

BMC (Hexapole) Magnet.
If the red, green and blue dots are not balanced or aligned, then
use the BMC magnet to adjust in the manner described below.

Fix a Permalloy assy corresponding to the misconverged
areas.

FOCUS adjustment should be completed before W/B adjustment.

1.

Receive digital monoscope pattern.

2.

Set "Picture Mode" to "Standard".

3.

Set S2801 to mechanical center position.

4.

Adjust focus VR so that the center of the screen becomes just

focus.

5.

Adjust S2801 when corner focus is unbalance is right and left.

6.

Change the receiving signal to white pattern blue back.

7.

Confirm Magenta ring is not noticable. Incase magneta ring is

obvious, reset S2801 to mechanical center position and then

adjust FOCUS VR to balance between MAGENTA RING and

FOCUS.

WITH COMMANDER).

2) Input white raster signal.
3) Set the PICTURE to minimum.
4) Select WHB 04 "GCT" and WHB 05 "BCT" with [1] and [4],

and adjust the level with [3]  and [6] for the best white
balance.

5) Set the PICTURE to maximum.
6) Select WHB 01 "GDR" and WHB 02 "BDR" with [1] and [4],

and adjust the level with [3] and [6] for the best white
balance.

7) Write into the memory by pressing [MUTING] then [0].

3. SUB BRIGHT ADJUSTMENT
1) Set to service mode.
2) Input a staircase signal of black to white from the pattern

generator.

3) BRIGHTNESS .... 50%.

PICTURE ............ MINIMUM

4) Select WHB 07 "SBR" with [1] and [4], and adjust WHB 07

"SBR" level with [3] and [6] so that the second stripe from the
right is dimly lit.

1. G2 (SCREEN) ADJUSTMENT
1) Set the PICTURE to normal.
2) Put to VIDEO input mode without signals.
3) Connect R, G and B of the C6 board cathode to the

oscilloscope.
