Mechanically Adjusting Dmd Convergence - Christie CineLife+ CP4415-RGB Service Manual

Mechanically adjusting DMD convergence

Use the convergence knobs behind the Service door to mechanically adjust convergence.
1. Before adjusting DMD convergence, make sure the projector has reached a steady operational
state.
If switching from a white or bright test pattern to a dark convergence test pattern or if
warming up the projector after a shutdown, allow 15 minutes for stabilization so the optics can
reach a steady state.
2. Make sure the electronic convergence (ECC) is defaulted before doing mechanical convergence.
3. In the right toolbar, select Test Patterns.
4. Select the RGB-4K-Convergence test pattern and display it full screen.
Make sure the Uncorrected Color Box option is selected.
5. Open the Service door on the side of the projector.
6. To adjust the convergence knobs, use the 3 mm driver included with the projector.
If adjusting by hand without using the tool, pull out the convergence adjustment knobs to
engage them.
