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.
To enter this adjustment mode, you may also select DIGITAL ARRAY from the Set Up menu. However, this will display a message
prompting you to press the front panel DIGITAL ARRAY button.
NOTE: To save your adjustment data into memory, press the front panel DIGITAL ARRAY button or the remote control MOVE
Button. If you do NOT wish to save your adjustment data into memory, turn the TV OFF or press the remote control PIP
button. When the TV is turned ON again, your old convergence data will be restored.
When adjusting convergence, always start at the center of the screen.
