Solution

to all controls

If possible, turn off the projector, then 

unplug the power cord and wait at least 30 

seconds before reconnecting power.

Lamp burns out or makes a 

popping sound

When the lamp reaches the end of its useful 

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.
