CONVERGENCE ADJ. 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 1 horizontal and 1 vertical line at the center of 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 CONVERGENCE ADJ. from the SETUP menu. However, this will display a message prompting you to press the front panel CONVERGENCE ADJ. button. Press the THUMB STICK , , , 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 CONVERGENCE ADJUST button when adjustment is done. This will save your adjustment memory. NOTES: 1. Only a momentary press of the CONVERGENCE ADJUST button is necessary to start CONVERGENCE ADJUST mode. 2. The color being adjusted will blink (red or blue) to indicate color you are adjusting. 3. To save your adjustment data into memory, press the front panel CONVERGENCE ADJUST button. If you do NOT wish to save your adjustment data into memory, turn the TV OFF. When the TV is turned ON again, your old convergence data will be restored. 43

CONVERGENCE ADJ.
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 1
horizontal and 1 vertical line at the center of 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.
