Adjusting Boresight - Christie CP2208-LP Service Manual

Adjusting boresight

Perform a boresight adjustment when the image cannot be focused uniformly on the screen by
aligning the projector to the screen and focusing the lens.
Ensure that the projector is perpendicular to the screen before adjusting boresight.
Ensure that the boresight set screws are adequately tightened. Not adequately tightening the screws
can result in excessive on-screen image vibration. After adjusting boresight, evaluate the on-screen
image vibration and re-adjust if needed.
1. Remove the lens surround.
2. Display the DC2K Boresight test pattern (on page 87).
This test pattern assists with adjusting the boresight for the three focus points.
3. Set the zoom of the lens so the test pattern fills the screen size.
4. Set the lens focus to the middle of its range.
5. Loosen the three set screws (A, B, C).
