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 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 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.
To enter this self-adjust mode, you may also select DIGITAL ARRAY from the SETUP menu. However, this will
display a message prompting you to press the front panel DIGITAL ARRAY button.
Use the number buttons to select which point to adjust: (1) - Upper Left, (2) - Upper Middle, (3) - Upper Right, (4) -
Center Left, (5) - Center, (6) - Center Right, (7) - Bottom Left, (8) - Bottom Middle, (9) - Bottom Right.
Press the CURSOR buttons to move the displayed color up, down, left, or right.
Press MENU to change the color you want to adjust.
Press the front panel DIGITAL ARRAY button or the remote control MOVE button when adjustment is done. This
will save your adjustment into memory.
NOTES: Only a momentary press of the DIGITAL ARRAY button is necessary to enter DIGITAL ARRAY
convergence adjustment mode.
Do not press the DIGITAL ARRAY button for more than three seconds. This is only for extreme cases of
misconvergence and requires assistance from service.
