This TV has three color projection tubes: one for red, green, and blue. When mixed together
in the proper portions, 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 produce of aligning these picture beams is called “convergence”.
Attention:
• Please have your TV on for at least 20 minutes before using this feature.
• This adjustment will be needed only when the colors of the characters/lines are separated
and lack in distinction. If not, please don’t perform the adjustment.
Colors may become separated after the TV has been moved, or over a long period of time if
regularly subjected to low levels of vibrations. If the colors become separated, please perform
the adjustments below again.

Notes:
• When you adjust the convergence, make sure you start with the center position (position 5),
and work your way around radially for best results.

the whole screen. In other positions, you are making the adjustment only in that area.
• You can reset the adjustment if you do not like the results.
