MAGIC FOCUS
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 colors 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 the
TV to self-adjust. This process will take approximately 90 seconds. If this button is pressed
during this 90 second period, no change is picture quality will occur. After this 90 second self-
adjust period, picture quality will be optimum. (Do not move the TV during self-adjust.)
To enter this self-adjust mode, you may also select MAGIC FOCUS from the SETUP Menu.
However, this will display a message prompting you to press the front panel MAGIC FOCUS
button.
NOTES: Only a momentary press of the MAGIC FOCUS button is necessary to start AUTO
DIGITAL CONVERGENCE. At anytime during this convergence correction process, you may
press the MAGIC FOCUS button to exit the MAGIC FOCUS mode.
Do not press the MAGIC FOCUS button for more than three seconds. This is only for extreme
cases of misconvergence and requires assistance from service. If one of the pictures shown
below appears on the television screen, press the MAGIC FOCUS button a second time to exit
this manual set up mode.
