ADJUSTMENT INSTRUCTION
1. Application Object
These instructions are applied to all of the color TV, MC-036A. (RF: PG50Ch or A/V input: RED pattern) (4) Loosen fixed screw of DY and closely to CPT funnel part. (5) Check the center of screen that purity magnet of CPT by crossing adjustment. At this time, 4 & 6 pole magnet is located to magnet of nothing. (6) Move the DY to make equal red on whole screen and it does not to make the DY by fixed screw after check a simple color of Red/Green/Blue and white raster whether or not it is a pollution of color. (At this time, take care raster of screen and DY must fixing in the condition which maintains a horizontality.) (7) Check the TV set by move direction.

2. Notes
(1) Because this is not a hot chassis, it is not necessary to use an isolation transformer. However, the use of isolation transformer will help protect test instrument. (2) Adjustment must be done in the correct order.But the adjustment can be changed by consideration of mass production. (3) The adjustment must be performed in the circumstance of 25±5°C of temperature and 65±10% of relative humidity if there is no specific designation. (4) The input AC voltage of the receiver must keep 220V±10% in adjusting. (5) The receiver must be operated for about 15 minutes prior to the adjustment.

4-2. Convergence adjustment
These adjustments can the best condition of focus after finished purity adjustment. (1) Receive the signal of cross hatch that color is black. (2) Adjust brightness and luminosity till dot appear 9 ~12. (3)Open angle of the two tab of 4 pole magnet by isogonic angle and accord with vertical line of red and blue color in the middle of screen. (4)Maintain as angle of 3) and rotate the tab to accord with vertical line of Red and Blue color in the middle of screen. (5) Open angle of the two tab of 6 pole magnet by isogonic angle and accord with vertical line of Red/Blue and Green. (6) Maintain as angle of 5) and rotate the tab to accord with horizontal line. In case of twisted horizontal line,repeat adjustment of 3) ~ 5) remembering the movement of Red/Green/Blue color. (7) Move the DY to best condition of convergence and attach the CPT to a rubber-chock for fixed DY.

3. Focus adjustment
1. Preliminary steps
(1) Tune the TV set to receive a digital pattern. (SVC mode: Automatically mode change the STANDARD MODE)

2. Adjustment
(1) Adjust center focus volume of FBT for the best focus of vertical line (B). (2) Adjust the upper focus volume of FBT for the best focus of area (A). (3) Repeat above step 1) and 2) for the best overall focus.

4-3 Screen voltage adjustment
1. Preliminary steps
(1) Turn on the TV set. (2) This adjustment should be performed after warming up for more than 15 minutes.

2. Adjustment
(1) Adjust in RF non-signal. (2) Press the ADJ key of SVC remote controller to make horizontal line.

5. White balance adjustment

4. Purity & Convergence adjustment
4-1. Color purity adjustment
(1) Magnetic room set to destination magnetic and horizontal magnetic set to zero. (2) It makes CPT or CABINET enough to demagnetization. (3) Self-adjustment: Adjust by input of Green raster signal Manual-adjustment: Receive the signal of red raster.

This adjustment should be perfomed after screen adjustment. This adjustment set the self-adjustment rule.

1. Test Equipment
(1) Automatic White balance meter: Incase of self-adjustment (2) White balance meter(CRT Color Analyzer, CA-100): 1 EA (3) A SVC remote controller.
