Adjusting CRT Color Convergence-
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”.
A t t e n t i o n :
• This adjustment will be needed only when the colors of the characters/iines 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 seperated, please perform
the adjustments below again.
