Auto Digital Convergence Adjustment
Please turn ON your television for at least 20 minutes before using this feature.
The Magic Focus button on control panel will not work when adjustment mode is set to Manual (see page 23-24).
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 located on the front control panel, which allows the
TV to self-adjust. Press this MAGIC FOCUS button and the convergence self adjustment will start and this process will take
approximately 20 seconds. If this button is pressed during this process, no change in picture quality will occur. After this 20 second
self-adjust period, picture quality will be optimum (do not move the TV during self-adjust).
You may also select MAGIC FOCUS TUNE UP from the Setup Menu.

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 MAGIC FOCUS
mode. However, the convergence correction process needs to be completed to SAVE the new corrected convergence
data.
