CONVERGENCE
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 color
tubes can produce any color. To produce these 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.
Note: If the 60SX3B/60SX4K or 50SX5P is unplugged from the wall outlet or there is a
power loss, wait 30 seconds after the set is plugged in or power returns before turning the
set on.
