7 (Optional) Converge your TV.
Your projection TV has three color projection tubes-one for
red, one for green, 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, the
beams must be precisely aligned over each other so that the
colors can be mixed. The process of aligning these picture
beams is called "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 TV or notice colored rings or halos
around objects in the picture, you may want to converge
(align) the colors.
To simplify convergence, an on-screen menu is provided that
allows you to display a test pattern of lines on the screen.
Properly converged, the lines appear white-which is actually
a combination of the output of the three 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.
To Converge (Align) the Colors.

Turn on the TV and select a channel that is active in your
area. Allow the TV to operate at least ten minutes before
