Adjusting The Color Convergence - Toshiba 50H71 Owner's Manual

Adjusting the color convergence

This projection TV uses three separate TV tubes: red, green, and blue.
The red, green, and blue images are projected onto the screen where
they converge to form a full-color picture. You can see a clear picture
only when the three images converge correctly. Convergence may drift
over time or if you move the TV. If you can see clear images on your
TV screen, skip this procedure.
This adjustment should be made only after the TV has been on for at
least 30 minutes.
To check and adjust the color convergence:
1. Press MENU, and then press x or • until the PICTURE menu
appears.
2. Press y or z to highlight CONVERGENCE (see illustration,
below left).
3. Press x or • to display the Center Convergence menu (see
illustration, below right).

If you see separate red, blue, or green crossed lines (or red or blue
shadows next to white lines), you need to adjust the convergence.
4. Press ENTER to highlight RED or BLUE, depending on which
color needs adjusting. If both red and blue need adjusting, you
will need to perform steps 4 and 5 twice.
5. Press y (up), z (down), x (left), or • (right) on the remote
control to converge the red or blue line into the green line, which
will turn completely white when correctly adjusted. When color
convergence is correctly adjusted, you will see two single crossed
white lines.
6. Press EXIT to display the Circumference Convergence menu.
7. Press the corresponding Number button (1–4 and 6–9) to select
the area you want to adjust (see illustration, below left).
8. Press ENTER to highlight RED or BLUE, depending on which
color needs adjusting (see illustration, below right). If both red
and blue need adjusting, you will need to perform steps 8 and 9
twice for the selected area.
