Troubleshooting
Problem: Nothing on projection screen
Make sure that the power cord is properly connected to a fully
functional 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 you have removed the lens cap on the projection
lens at the front of the projector.
Make sure the lamp is switched on.
Check the projector’s lamp to ensure that it is securely con-
nected in the lamp module. See “Replacing the Projection
Lamp” on page 41.
Make sure that the cables do not have any bent pins.
Problem: Color or text not being projected
You might need to adjust the brightness up or down until the
text is visible. Refer to “Brightness” on page 28 for more infor-
mation.
Problem: The screen resolution is not right
Make sure the computer’s video card is set for a resolution of
no greater than 1280x1024.
Problem: Image isn’t centered on the screen
Move the projector to reposition the image.
Reposition the image using the software. Refer to “Horizontal
position” on page 34 and “Vertical position” on page 34.
Be sure the projector is at a 90 degree angle to the screen.
Problem: Only the start-up screen displays
Verify that the cables are connected correctly. See page 12
through page 14 for connection procedures.
Verify that the proper input source is connected and active. See
“Source (keypad only) or Comp and Video (remote only)” on
page 26.
