Pressing the 1 or 4 buttons moves the cursor on the screen. The cursor
will follow the vortex pattern shown in the drawing above. There are 81
separate points that can be adjusted. You can now adjust each point by
moving the joystick on the remote. The point in the center of the cursor
will be moved in the direction the joystick is moved. Continue to adjust
each point until your green picture is correct. Repeat this procedure for
red and blue and lay those pictures over green.
Auto Registration Adjustment
The Auto registration system or Auto Focus customer adjustment does
not optimize the centering and skew each time it is pressed. What it
does is memorize the settings for an already optimized picture and
adjust convergence back to that setting. This means that when the
customer presses the Auto Focus button on the front of the set, the func-
tion performed adjusts the center and skew controls for each color so that
it matches what was previously memorized. The factory or the servicer
sets the memorized information by pressing the Auto Focus button while
in the test mode.
Therefore, whenever a servicer adjusts convergence, they should press
the Auto Focus button after, and only after, they have a perfect picture.
Generally this would be the last thing done before finishing the repair. It is
also important that this be done every time that adjustment is made if
Auto Focus is not run in the test mode
Auto Registration Offset Adjustment
This adjustment may need to be performed if errors occur while doing
Auto Focus or the picture produced is off center horizontally.
Confirm that the OSDH value is 32. Go to the PWM2 adjustment in the
PJED mode. A djust the center marker to the horizontal center of the
picture (Between the O and the N in the SONY log). However, the data
value must be above 33 in order for the set to work correctly. If the value
is below 34, set it to 34 even if the marker is slightly off center.
This number must be bigger than 33.
