Digital Setup - Zenith IQB50M92W Operating Manual

Digital Setup

Your Zenith 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, Zenith 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 press the front panel DIGITAL SETUP 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.
