6. Rotate the 6-Pole magnets keeping the angle between

two 6-Pole magnets until horizontal Red and Blue lines
are unified.

(4) Dynamic Convergence (DYC) Adjustment

1. Vertical Line Adjustment : Adjust by moving DY right and

left.

2. Horizontal Line Adjustment : Adjust by moving DY up

and down.

6. White Balance Adjustment

6.1 Test Equipment 

(1) Automatic White Balance meter(Can generate Low/High

light pattern)

(2) White Balance meter(CRT color Analyzer, CA-100)
(3) SVC Remote control for adjustment

6.2 Preliminary steps

Do screen adjustment first.

6.3 Adjustment  

(1) White Balance should be adjusted with the SVC remote

control.

(2) Enter into adjustment mode by “INSTART” button.                
(3) Adjust the item with CH 

D

,

E

.                      

(4) Adjust the data with VOL 

F

G

.                          

(5) Adjustment Procedure

1. Adjust “CONTRAST” and “BRIGHT” so the bright level to

be 35Ft_L.           

2. Select G-DRIVE(SUB 7) and adjust Y coordinate in High

Light and select B-DRIVE(SUB 8) and adjust X
coordinate so the color coordinates in High light as to
be the values  in Table below.       

3. Adjust “CONTRAST” and “BRIGHT” so the bright level to

be 4.5Ft_L.                        

4. Select G-CUT(SUB 5) and adjust Y coordinate in Low

Light and select B-CUT(SUB 6) and adjust X coordinate
so the color coordinates in Low light as to be the values
in Table below.

5. Repeat 1 ~ 4  until the color coordinates in High and

Low color satisfies the Table.                                             

6. Check the adjusted color coordinates with the white

balance meter.                  

7. Focus Voltage Adjustment

Adjust after operating the receiver enough.                         

7.1 Preliminary steps

(1) Receive Digital Pattern.                                                          
(2) Set Picture condition to “CLEAR”. 

7.2 Adjustment

Adjust center focus with upper Focus volume and adjust
corner focus with lower Focus volume.
Repeatedly adjust focus until getting proper focus.

8. Sub-Brightness Adjustment 

Do white balance adjustment first.                   

8.1 Preliminary steps

(1) Receive Mono Scope.                                                             
(2) Set Picture condition to “CLEAR”. 

8.2 Adjustment 

(1) Select “SUB BRI” mode pressing “ADJ” button on the SVC

Remote control. 

(2) Adjust until number “2” almost disappears on Gray Scale

of Mono Scope signal by VOL 

F

key.

Adjust 21” FLAT Model until number “3” almost disappears.

9. Sub-Tint Adjustment 

This adjustment must be done when the TINT is on.

(1) Receive SMPTE.
(2) Select the TINT adjustment mode(Sub-Tint) with the ADJ

key(or SVC key).

(3) Adjust the up and down cyan color same with VOL 

F

G

key.
