Troubleshooting Troubleshooting (Continued) Problem Lamp burns out or makes a popping sound Projector suddenly shuts down and the power button LED blinks rapidly Speaker does not operate Solutions When the lamp reaches its end of life, it will burn out and may make a loud popping sound.

To replace the lamp, follow the procedures in the "Replacing the Projector Lamp Module" section of Chapter 7. An over-temperature event has been detected. This usually occurs when either the airflow to the unit has been obstructed or a fan has failed. If airflow is obstructed, remove the obstruction, unplug the projector, re-plug the projector, and restart. If a fan has failed or an over-temperature event occurs a second time, have the projector serviced or repaired. 1. Make sure the audio cable is correctly connected to the projector and the audio source. 2. Make sure the audio source is operating properly. 3.
