CONVERGENCE ADJUST

Your Projection TV has three color projection tubes: one for red,
one for green, one for blue. When mixed together in the proper
proportion, the output of these three colors, however, 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 if, after a time, you notice color rings or halos around
objects in the picture, you may want to converge (align) the colors.

To simplify convergence, the following feature allows you to
display a test pattern of horizontal and vertical lines on the screen.
Properly converged, the lines appear white, which is actually a
combination of the outputs of the three color tubes. The output of
the green tube is stationary. The outputs of the red and blue tubes
can be adjusted. When properly aligned, the outputs of all three
tubes should be directly over each other to produce the white lines.
