Magic Focus - Hitachi 43FDX20B Operating Manual

SET UP

MAGIC FOCUS

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 willl start and this process will take approximately
40 seconds. If this button is pressed during this process, no change in picture quality will occur. After this 40 second self-adjust period,
picture quality will be optimum. (Do not move the TV during self-adjust.)
You may also select MAGIC FOCUS from the SETUP Menu.
NOTES: 1. For MAGIC FOCUS to perform at it's best, the television must be turned "ON" and heat run for a minimum of 20
minutes before pressing MAGIC FOCUS on the front panel.
2. 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.
