  When R, G, B-CUT, BRT, or S-BRT is selected,

the screen becomes one horizontal line when

  Even when BRT is adjusted, the value will

not be memorized.

Caution items

1. After entering service adjustment mode, perform 

adjustment after making notes of the values for each
item.
The written values (data) differ according to the set.
Using the noted values as a reference facilitates the 
adjustment.

2. The item [OPT 

] (OPT adjustment) in the 

contents for service adjustment mode is for 
adjustment at the plant.
Stay away from this item, as it means adjustment of 
all items.

Caution items

1.  When H-key (vertical pin keystone distortion) is adjusted, the vertical position changes, and V-POS (vertical 

position) must be adjusted.
However, when the vertical position is raised too much, the on-screen display no longer can be seen.

2. The item [OPT 

] (OPT adjustment) in the contents for service adjustment mode is for adjustment at the plant.

Stay away from this item, as it means adjustment of all items.

3.  After entering service adjustment mode, perform adjustment after making notes of the values for each item. The

When the picture or the deflection yoke ha been exchanged, perform all of the following adjustment in the following order.
When no part exchange has been done, adjustment still must be performed.

Confirmation of demagnetization

VRS adjustment

Purity adjustment

Convergence confirmation and adjustment

H-V (distortion, position) adjustment

White balance adjustment

Sub-brightness adjustment

Focus adjustment

Overall inspection

Purpose: Facilitation of adjustment after installation

1. Push the deflection yoke all the way to the front and fix it 

provisionally.

2. Align the knobs of purity magnet, 4-pole convergence 

magnet, and 6-pole convergence magnet to minimize the 
composite magnetic field.

3. Demagnetize the front and the rear of the picture tube, 

the left and the right side of the cabinet, etc. with a 
demagnetization coil.
At this time, keep the demagnetization coil away from the 
deflection yoke.

4.  Receive a color pattern and perform aging for at least 

one hour.

Purpose:  Adjusting the red, blue, and green electron beams so that they hit

the specified fluorescent substance correctly.

Demagnetizer, color bar generator

Crosshatch pattern

1. Receive a crosshatch pattern.
2.  Confirm that the knobs of purity magnet, 4-pole 

convergence magnet and 6-pole convergence magnet all 
are aligned.

3. Loosen the screws fixing the deflection yoke and 

provisionally fix the deflection at the very front position with 
adjusted inclination.

4.  Adjust the VRS magnet (Fig. 2) so that the horizontal lines 

of the crosshatch pattern become level (Fig. 3).

5. Next, perform purity adjustment.
