Moving the joystick changes data. Moving the joystick up or down
changes the V data, and moving the data left or right will change the H
data. Data that does not have separate V and H adjustments can be
adjusted by moving the joy stick up or down or left or right.

Let's look at how we would perform adjustments from a worst-case sce-
nario. An example would be if all of the data were lost on the BD board
since that is where all convergence data is stored.
If this scenario is encountered, the first thing that should be done is to
enter the service mode got the PJED section and enter the default values
that are in the service manual. After doing this, press Muting and Enter
to save these values. The first 15 of these adjustments, with the excep-
tion of 13 PWM2, will not have to be adjusted after this. The default value
will remain.
Next cover the blue and red tubes so only green can be seen. We use
green as a reference for the other two colors so it must be correctly ad-
justed first. Press 6 on the remote so that a crosshatch can be seen over
a black screen. If the V Size, H Size, V Pos and H Pos are not correct,
use the 2 button to enter the VDSP category and make the necessary
changes to those adjustments. If these adjustments are correct, then you
can do the coarse adjustments for green.

There are two sets of adjustments for convergence, coarse and fine. The
coarse adjustments are similar to older convergence systems. The fine
adjustments are the new point type. The coarse adjustments must be
done first. You should try to achieve the best picture possible using these
adjustments. The table below shows the adjustments available for each
color:

Once the coarse adjustments have been completed, it is time to perform
the fine adjustments. Press 9 on the remote to enter the fine adjustment
mode. The display will blank and a cursor will appear in the center of the
screen.
