Section 5: Troubleshooting
• The DMDs may be overheated. Check for an alarm condition.
• An interlock may be interrupting lamp function.
• Replace the lamp.
5.2.3 Flicker, Shadows Or Dimness
Check for the following:
• Ensure the shutter is open.
• LampLOC™ may need re-adjustment.
• LampLOC™ may be in the middle of its adjustment. Wait approximately 2-3 minutes.
• Adjust LampLOC™ motors manually, via the
Main
menu. Confirm all stepper motors are operational by
watching on screen with a full white test pattern while adjusting.
• Increase lamp power, if possible. Lamps which are near end of life may not operate reliably at lowest power
range.
• Fold mirror misalignment (a Christie accredited service technican is required to resolve the issue).
5.2.4 LampLOC™ Does Not Seem to Work
Check for the following:
• 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 1 of the motors is damaged, the
stepper driver board has malfunctioned or there is a faulty connection.
5.2.5 LiteLOC™ Does Not Seem to Work
Check for the following:
• Ensure LiteLOC™ is set and enabled in the
Lamp
menu.
• 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).
