Does not turn on • Check that the power cable is plugged in and that the power button on the
projector cabinet or the remote control is on. See pages 19 and 20.
• Ensure that the lamp cover or lamp housing is installed correctly. See page
41.
• Check to see if the projector has overheated or the lamp has reached the
end of its usable life. If there is insufficient ventilation around the projector or
if the room where you’re presenting is particularly warm, move the projector
to a cooler location.
• The lamp may fail to light. Wait a full minute and then turn on the power
again.
• The lamp has reached the end of its usable life. Replace the lamp.

and the notebook PC before turning on the power to the notebook PC. In
most cases signal cannot be output from RGB output unless the notebook
PC is turned on after connecting with the projector.

result of the computer’s screensaver or power management software.
