Troubleshooting
LEDs
The Alarm LED on top of the projector (Figure 11 on page 18) will alert you to certain problems.
•A solid red Alarm LED means it is time to change the lamp. See page 31.
•A blinking red Alarm LED means the projector is overheat- ing. Turn off the projector and allow it to cool.
The other LED on top of the projector indicates the normal oper- ating state of the projector.
•A solid green LED means the projector is on.
•A blinking green LED means the projector is in DPMS mode. See page 25.
•An blinking orange LED means the projector is going into standby mode; a solid orange LED means the projector is in standby mode. See page 14 for detail on standby mode.
Problem: The projector is not running
•Make sure that the power cord is properly connected to a func- tional AC electrical outlet. Make sure that the power cord is also properly connected to the projector.
•If the projector is plugged into a power strip, make sure the power strip is turned on.
•Make sure the projector is turned on. Verify that the LED is solid green.
Problem: Projector is running, but nothing appears on projec- tion screen
•Make sure you have removed the lens cap on the projection lens at the front of the projector.
•Verify that the Black button on the remote is not activated.
•Check the projector’s lamp housing to ensure that it is securely connected to the bottom case. See “Replacing the Projection Lamp” on page 31.
