SUPER CONTR (SUPER CONTRAST)
Turn on SUPER CONTR to improve picture detail in areas of high brightness.
CONVERGENCE CORRECTION
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, Hitachi incorporates a function called MAGIC FOCUS, which
allows the TV to self adjust so it can obtain the highest quality picture possible. Press
the MAGIC FOCUS button located on the front panel to allow the TV to self adjust. This
process will take approximately 2 minutes. If this button is pressed during this 2 minute
period, no change in picture quality will occur. After this 2 minute self adjust period,
picture quality will be optimum. (Do not move TV during self adjust.)
To enter this self adjust mode, you may also select Convergence Correction from the
VIDEO Menu. However, this will display a message prompting you to press front panel
MAGIC FOCUS button.
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:
Only a momentary press of the MAGIC FOCUS button is necessary to start AUTO
DIGITAL CONVERGENCE. At any time during this convergence correction process, you
may press the MAGIC FOCUS button to exit the convergence correction mode.
Do not press the MAGIC FOCUS button for more than 3 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.
