MAGIC FOCUS
Your projection TV has three color projection tubes: one for red, one for gree, 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 function called MAGIC FOCUS,
which allows the TV to self adjust. This process will take approximately 90 seconds. If
this button is pressed during the 90 second period, no change in picture quality will
occur. After this 90 second self adjust period, picture quality will be optimum. (Do not
