The screen should be adjusted with a white pattern (snow from the tuner
should do or turn the user COLOR control all the way down to get a
black and white picture). Put the set in Service mode (horizontal line)
if it has such a switch in the back or inside. If not, just use
the raster in a darkened room. Adjust screen for a dim white
line (raster). If the line is not white at its dimmest point, you will
need to adjust the drive and cutoff controls for R, G, & B.

Alternatively, you can use the following procedure:
Turn R, G, and B screen (or background) controls down. Now turn color
control fully counterclockwise -- off. Now turn up red screen until the
screen just shows a red hue. Now turn red gun down until red tint just goes
away. Now do the same with the green and blue screen controls. Now adjust the
two DRIVE controls for the best black and white picture. That`s all there is
to it. I don`t like to work with just a thin "SETUP" line. Cartoons seem to
be the best thing to have on while doing the above procedure. You can
also use just plain snow (no program) if you prefer. If you can obtain a
good b@w pic. when you`re done, the tube is good and the set if most
likely functioning properly. Be patient and go slow while watching the
large mirror that you are using during this procedure. (LEE)
