Use the Cursor Up-Down button to highlight the selection.
Press the Cursor Right button to make the selection. In the
second menu:
• MANUAL CONVERGENCE WO VIDEO means that the
screen behind the adjustment grid will be blank. This does
not mean that Convergence can be performed without a
signal being applied to the set.
• MANUAL CONVERGENCE W VIDEO displays the applied
video behind the adjustment grid.
• RESTORE FACTORY loads the values from the last saved
convergence alignment.
• RESTORE DEFAULT loads values from the ROM on the
ACS Microprocessor.
• RESTORE FACTORY or RESTORE DEFAULT will
overwrite all eight Convergence modes.
If the ACS module has been changed, there may not be data in
the NVM for RESTORE FACTORY. The RESTORE DEFAULT
settings will then be loaded.
An internally generated grid will be displayed in the
Convergence mode as shown on the following page. The
shaded area is the visible screen area. Horizontal lines A and
M are displayed on the top and bottom edge of the visible
screen area. Lines 1 and 15 are also displayed on the left and
right edge of the visible screen area. Vertical line 0 is adjustable
but not visible.

8.4.6 Single Tube Replacement Convergence
If a single tube has been replaced, it is not necessary to do a
Major Convergence alignment.
1. Enter the Convergence mode and select the adjustment
needed.
2. Select "Red to Green", for example if the Red tube has
been replaced.
3. Adjust the centring rings on the CRT to centre the Red
pattern onto the Green pattern.
4. Starting with the centreline, adjust the Red icon onto the
Green pattern. Best results are obtained when navigating
from left to right. Two or three passes may be necessary to
obtain satisfactory results.
