Problem Solving

This section explains how to interpret the projector’s status lights, solve problems with the 
picture and remote control, and contact technical support.

The lights on top of the projector indicate the projector’s 
status and let you know when a problem occurs.

If the projector isn’t working correctly, first press the 
P

power button, let the projector cool down, turn off the 

power switch on the back, and unplug the power cord. 
Then plug the power cord back in and turn on the 
projector. If this doesn’t solve the problem, check the 
status lights on top of the projector.
