Flicker, Shadows Or Dimness; Lamploc™ Does Not Seem To Work; Liteloc™ Does Not Seem To Work - Christie CP2000-M User Manual

Section 6: Troubleshooting

6.2.3 Flicker, Shadows Or Dimness

1. Ensure the douser is open.
2. LampLOC™ may need re-adjustment.
3. LampLOC™ may be in the middle of its adjustment. Wait approximately 2-3 minutes.
4. Adjust LampLOC™ motors manually, via the CDP. Confirm all stepper motors are operational by
watching on screen with a full white test pattern while adjusting.
5. Increase lamp power, if possible. Lamps which are near end of life may not operate reliably at lowest
power range.
6. Fold mirror misalignment (Christie service required).
6.2.4 LampLOC™ Does Not Seem to Work
If the Do Auto LampLOC™ function does not work, try adjusting the lamp position manually, via the
LampLoc>Manual Adjust menu. Observe screen brightness by adjusting the XYZ values or use a light meter
to check for changes in brightness.
• Use a Minolta™ T10 illuminance meter (hand-held): Position meter in center of screen to take reading.
OR:
• Use a Minolta™ LS-100 luminance meter: Point the lens at the center of the screen to take a reading. Retake
the reading each time an adjustment is made.
Always adjust XY values before adjusting Z values. Repeat XY adjustments any time Z is adjusted. If
brightness levels are not changing when adjusting the XYZ motors it is likely one of the motors is damaged,
the stepper driver board has malfunctioned or there is a faulty connection.
6.2.5 LiteLOC™ Does Not Seem to Work
1. Ensure LiteLOC™ is set and enabled in the Advanced: Lamp menu, via the web user interface.
2. If the lamp power has reached its maximum setting, the light intensity reading still can not meet the target;
however, it appears it is not functioning. For example, if the lamp power range is from 1KW (light
intensity reading 4000) to 3KW (light intensity reading 6000) and the light intensity is set to 10,000 it will
never find the maximum lamp power level because the light intensity is set too high. In this case, simply
reduce the LiteLOC™ value within (4000, 6000).
