4. Check the centering of the crosshatch pattern. Use the center cross hairs of the
convergence overlay, or two pieces of string stretched diagonally across the
screen, to locate the center.
5. If the horizontal position is off, use the channel up or down key to select the HPOS
register. Use the volume key to center the pattern.
6. If the vertical position is off, use the channel up or down key to select the VPOS
register. Use the volume key to center the pattern.
7. Turn the power off to save all adjustments.
Section 5: GREEN GEOMETRY
1. Enter the service adjustment mode and then enter the convergence adjustment
mode.
2. Push the 100 key to turn off the red tube, and CH RTN/ENT to turn off the blue
tube.
3. Place the convergence overlay on the screen and align the center cross hairs with
the center of the screen.
4. Use low tack drafting tape to secure the overlay to the screen. Make the overlay
as flat as possible against the screen to reduce parallax errors.
Readme: If the microcomputer memory IC (QA02) has been replaced, or the
crosshatch pattern is not reasonably close to the overlay pattern, make the
adjustments in Section 9. (WID, HIT, & VLIN ADJUSTMENTS). Then proceed
with step 5.
5. Push the 3 key on the remote until the blinking cursor in the upper left corner of
the screen is green.
6. Move the blinking cursor to the right with the 6 key, then down with the 8 key, until
it is one line to the right of screen center. The 4 key moves the cursor to the left,
and the 2 key moves it up.
7. Push the 5 key to lock the cursor in place.
8. Use the 2, 6, 8, and 4 keys to align the TV's convergence pattern to the overlay
pattern.
9. Push the 5 key to unlock the cursor.
10. Move the cursor to the next location and repeat steps 7 and 8. Continue around
the screen, clockwise, from the center to the edges. Repeat the entire procedure
to make fine adjustments.
Section 6: RED CONVERGENCE
1.
Remove the overlay and press the 100 key to turn on the red tube.
2.
Press the 3 key until the cursor turns red.
3.
Align the red convergence pattern to the green pattern, using the same
procedure used to align the green convergence pattern to the overlay.
