SET UP
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 function called MAGIC FOCUS, which allows the TV to self-adjust. This process will
take approximately 45 seconds. If this button is pressed during this 45 second period, no change in picture quality will occur. After this
45 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: 1. 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.
2. 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.

Depending upon input signal, it may be necessary to activate MAGIC FOCUS twice. While viewing a 480i, 480P, or 720P signal the
convergence will be corrected. However, when you change to a 1080i input signal you will need to activate MAGIC FOCUS again.
