Lamp Suddenly Goes Off; No Lamp Current Reading; Flicker, Shadow Or Dimness; Lamploc™ Does Not Seem To Work - Christie CP2000 Setup Manual

Section 5: Troubleshooting

5.2.2 LAMP SUDDENLY GOES OFF

1. Try increasing the lamp power (TPC Advanced Lamp menu).
2. The DMDs in the projection head may be overheated (this also triggers an alarm window at the
TPC).
3. An interlock may be interrupting lamp function.
4. Make sure the 220V connection near Panel C at the rear of the projector head (on the underside) is
plugged in.
5. Replace the lamp.

5.2.3 NO LAMP CURRENT READING

With this communication error, the lamp will be powered by the last lamp power setting in effect.

5.2.4 FLICKER, SHADOW OR DIMNESS

1. LampLOC™ may need re-adjustment.
2. LampLOC™ may be in the middle of its adjustment. Wait approximately two minutes.
3. Increase lamp power, if possible.
4. Determine if it is mid-level grayscale flicker (beating). Adjust 3-phase balancing for minimized
ripple (requires qualified service technician).
5.2.5 LAMPLOC™ DOES NOT SEEM TO WORK
UV Danger - The following procedure must be performed by qualified service
technicians only.
1. From the TPC Advanced Lamp menu, try adjusting lamp position using one button at a time.
Watch light level for changes indicating lamp movement.
2. If the motors do not respond via any TPC buttons, you can position the lamp manually within the
projection head.
5.2.6 LITELOC™ DOES NOT SEEM TO WORK
1. Ensure LiteLOC™ is set and enabled in the Advanced:Lamp menu.
2. Changing the Lamp Power setting disables LiteLOC™.
3. If the lamp power has increased to its maximum in order to maintain a LiteLOC™ setting,
LiteLOC™ is automatically terminated. If the values shown in the Advanced:Lamp menu
indicate the lamp power has reached this "over-drive" state, either reduce your LiteLOC™ setting
or install a new lamp.
