Appendices The projector stops responding to all controls If possible, turn off the projector, then unplug the power cord and wait at least 60 seconds before reconnecting power. Check that "Keypad Lock" is not activated by trying to control the projector with the remote control. Lamp burns out or makes a popping sound When the lamp reaches its end of life, it will burn out and may make a loud popping sound. If this happens, the projector will not turn on until the lamp module has been replaced. To replace the lamp, follow the procedures in the "Replacing the Lamp" section on pages 60-61.
