Flicker, Shadows Or Dimness; Lamploc™ Does Not Seem To Work - Christie CP2000-ZX Setup Manual

Section 5: Troubleshooting

5.2.3 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 min.
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).
5.2.4 LampLOC™ Does Not Seem to Work
1. If the Do Auto LampLOC™ function does not work, try adjusting the lamp position manually via the
Lamp > LampLOC > Manual Adjust menu. Watch the light level for changes indicating lamp
movement, both on the CDP readout and on screen with a white test pattern.
2. If the motors do not respond, you can position the lamp manually. UV danger. Qualified service
technician only.
3. If the lamp runs dim or the image displays poor uniform brightness, do the following:
• Check that the anode yoke is in the correct position.
• Check that the lamp extension nut is used with CDXL-30SD lamps only. You must remove the nut for all
other lamp types.
• Check that the flat part of the anode end of the lamp (if applicable) faces up in the anode yoke. For
CDXL-30SD lamps, the flat part of the anode end of the lamp should be positioned at the 2 or 10 o'clock
position.
• Check the position of the cathode lead. (Figure 5-1) UV danger. Qualified service technician only.
