Service Mode

Overview

The normal service mode has not changed greatly. It is still entered the
same way, but now the registration section is completely different. In this
section we will concentrate on the new registration system and how ad-
justments are done in the PJED Mode.

Remote Functions
The PJED mode is for adjusting convergence. When this display ap-
pears, you have entered into the registration adjustment section. The
buttons on the remote will no longer perform the same functions, but will
perform the functions shown in parenthesis on the remote drawing.
The 1 and 4 buttons on the remote are still used to change the adjust-
ment items.
The 2 and 5 buttons still can be used to change categories. If you
change categories, you will no longer be in the PJED mode.
The 3 button is used to change colors. Each time the button is pressed
the color to be adjusted will change from green to blue to red and
back to green and so on.
The 6 button is used to display the self-generated test pattern. Each
time it is pressed, the pattern will change from crosshatch over the
picture to dots over picture, to crosshatch over black to dot over black,
then back to OFF.
When the 7 button is pressed, INIT will show up in green on the screen.
If Enter is pressed, the sub deflection circuit will be turned OFF. In
order to turn it back ON, you must press 0 and Enter.
The 9 button is used to change between coarse and fine convergence
adjustments.
The Muting, 0 and Enter buttons perform their same functions.
