3-2. V-PIN and V-CEN ADJUSTMENT

Before beginning adjustment procedure:
•
Input a cross hatch pattern signal.
•
Face the picture tube in North/South direction and correct
rotation.
•
Video Mode: Standard (Reset)
1. Adjust service mode CXA2150D-1 04 VCEN so that top
pin and bottom pin are symmetrical from top to bottom.
2. Adjust service mode CXA2150D-1 05 VPIN so top and
bottom pin are symmetrical from top to bottom.
3. Lines should be straight from left to right. Check landing for
side effect.

3-3. CONVERGENCE ADJUSTMENT

Before starting convergence adjustments:
•
Set CONTRAST AND BRIGHTNESS control to 50%.
•
Input dot pattern signal.
Vertical and Horizontal Static Convergence
1. Disconnect dynamic convergence before adjusting static
convergence (CN5510), except for minor touch-up.
2. Adjust H.STAT convergence, RV 9001, to converge red,
green and blue dots in the center of the screen.
3. Adjust V.STAT magnet to converge red, green and blue
