Your projection
TV has three color
projection
tubes--one for red, one for
g_een,and one for blue. When mixed
together in the proper proportion,
the
output of these three color tubes can
produce many colors.
To produce
these colors, however,
the beams
must be precisely
aligned over each
other so that the colors can be mixed.
"[he process of aligning
these picture
beams is called setting the
6t
"
convergence
.
Over a period of time, the picture
tubes can drift out of alignment
due
to normal bumps and vibrations
or
moving the TV. If you move your
I_¢ or if, after a time, you notice
colored rings or halos around objects
in the picture, you may want to
conyerge
(align) the colors.
Ib simplify convergence,
an on-
screen menu is provided
that allows
ou to display a test pattern of four
hnes on the screen.
Properly
converged,
the lines appear
white-which
is actually a
combination
of the outputs of the
l_hree color tubes.
The position
of the
green lines is stationary.
The
positions
of the red and blue lines are
adjustable.
When properly
adjusted,
the red and blue lines should lie
directly
over the green lines to
produce
single white lines.
