Evaluating The Convergence Adjustments; Manually Overriding The Shutter - Christie CP2208-LP Service Manual

Evaluating the convergence adjustments

After completing the convergence adjustments, check the test pattern.
The test pattern should have the following characteristics:
• The center area should be perfectly aligned and display solid white pixels.
• The red color should be evenly spaced one quarter to one half a pixel out all the way around
the outer area and display cyan (green+blue) toward the center of the screen.
• The green and blue colors should always be perfectly aligned to each other (to within one
quarter of a pixel total in one or a combination of directions.).

Manually overriding the shutter

Use this procedure to override the shutter when it remains partially open or closed. When time
permits, replace the shutter assembly.
1. Turn the light off and allow the projector to cool for 15 minutes.
2. Remove the lens.
3. Reach through the lens opening and move the shutter up and down three times.
4. To determine if the douser is operating, tap the douser open and close icons on the touch
panel controller.
5. If the douser is not operating:
a) Disconnect the projector from AC power.
b) Remove the top skin (on page 32).
c) Remove the high security cover (on page 40).
d) Disconnect the shutter from the inline connector.
e) Remove the light dump.
f) Remove the two screws securing the shutter assembly.
g) Move the douser to the open or closed position.
