Section 7: Troubleshooting

7.1 Power

7.1.1 Projector Will Not Start

1. Check for green Main AC light on projector. If not on, check all breakers on projector and at the wall.

There are single-phase and 3-phase breakers.

2. Are the CP breakers staying on when enabled? If they are tripping to OFF position, there is an electrical

problem requiring investigation by a certified electrician.

7.2 Lamp

7.2.1 Lamp Does Not Ignite

1. If the lamp button is entirely disabled (not selectable at the TPC Main menu, indicated by a red X on the

lamp button), there is an interlock failure such as an open lamp door, failed lamp fan, etc. A flashing red

alarm window also indicates this. Refer back to solutions listed in

Table 3.2 on page 17.

2. For SSM communication failures, re-boot and try again.

3. If a DMD temperature is too high (DMD over critical temp limit), the lamp will not ignite. Cool the

projector and try again.

4. If the

Status menu indicates a ballast communication problem, re-boot and try again.

5. If the lamp does not ignite after a second try, replace the lamp.

6. If there is no buzzing indicating that the igniter is attempting ignition, there may be a problem with the

igniter (Christie service required).

7. If there is a brief buzz attempting ignition but a lamp does not ignite, the lamp likely needs to be replaced.

7.2.2 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 still

plugged in.

5. Replace the lamp.

7.2.3 No Lamp Current Reading

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