INITIAL SETUP
Yourprojection TV has throe color projection tubes: one for rod, one for green, one for blue. When mixed together in
the proper proportion,the output of these throe color tubes can produce any color. To produce these colors, howev-
er, 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 vibrationsor moving the
TV. If you move your TV, or if, after a time, you notice color ringsor halos around objects in the picture, you may want
to converge (align) the colors.
To simplifyconvergence, the following feature allowsyou to displaya test pattern of horizontaland vertical lineson the
screen. Properly converged, the lines appear white, which is actually a combinationof the outputsof the throe color
tubes. The output of the green tube is stationary.The outputsof the rod and blue tubes can be adjusted. When prop-
erly aligned, the outputsof all three tubes shouldbe directly over each other to producethe white lines.
