DIGITAL ARRAY
Your HITACHI 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.
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.
To simplify convergence, HITACHI incorporates a feature to allow you to display a test pattern of horizontal and vertical
lines at 9 different locations on the screen. Simply use the remote control to adjust the red and blue colors to match the
green. When properly aligned, the outputs of all three tubes should be directly over each other to produce the white lines.
