Before starting this adjustment, adjust the focus, horizontal size
and vertical size.

•

Receive dot/hatch signal.

•

Pic mode: Personal (Pic 90%, Brightness 50%, Col 50 %,

Hue 50%, Shp 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.

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)

•

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 "DYNAMIC".

3. (a) Adjust figure VR so that the center of screen becomes just

focus ( except 25").

(b) Adjust focus VR so that the lion teeth becomes just focus

(25" only).

4. Change the receiving signal to white pattern and blue back.

5. Confirm magenta ring is not over the limit sample.

Incase magenta fing is over the limit sample, adjust focus VR

to take balance of magenta ring and focus.

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 over the limit sample.

Incase magneta ring is over limit sample, reset S2801 to

mechanical center posotion and then adjust FOCUS VR to take

balance of MAGENTA RING and FOCUS.
