Adjusting the Color Projection Tubes

Your projection TV has three color projection tubes - one for red, one for
green, and one for blue. When the tubes are precisely aligned they create
the color images you see on the TV screen. Over time, the picture can drift
out of alignment due to normal component aging, bumps and vibrations,
or moving the TV. If you notice rings or halos around objects in the
picture, you may want to readjust the alignment of the picture tubes.
To readjust the picture tubes, first do an overall adjustment with the
Adjust Projection TV option in the Screen menu. The Adjust Projection TV
option is used to center the green tube and align the blue and red tubes
to the green tube. To make finer adjustments to specific areas of the
screen, use the Advanced Convergence feature described on the next
page.
To readjust the picture tubes:
1. Allow the set to warm up for at least 20 minutes.
2. Press the MENU button on the remote.
3. Press 3 to select the Screen option.
4. Press 4 to select the Adjust Projection TV option.
5. Press 1 to align Green Centering. Use the arrow buttons to center
green square on screen. Press MENU when done.
6. Press 2 to align Blue Convergence. Use the arrow buttons to align
blue crosshatch to green crosshatch. Press MENU when done.
7. Press 3 to align Red Convergence. Use arrow buttons to align red
crosshatch to green crosshatch. Press MENU when done.
8. If you want to make finer color adjustments, press 4 to select
Advanced Convergence (explained next) or press 0 to exit.

If you are unsure of the differences
among the modes, you may prefer to
leave the closed captioned mode set to

program in the primary language in
your area.
