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.
Press the CURSOR , to move the color displayed up or down.
Press the CURSOR , to move the color displayed left or right.
Press ENTER to change the color.
