Q:
What should I do if I see the a blue screen with the message No Signal?
A:
The projector has an on-screen help system you can use to solve this problem; see Using On-Screen Help. If the on-screen help does not solve the problem, check the following:
  • Make sure the cables are correctly connected. See Setting Up the Projector.

  • Make sure the power for your connected equipment is turned on.


  • If you've connected more than one computer and/or video source, you may need to press the Source Search button on the projector's control panel or the Search button or one of the Source buttons on the remote control to select the correct source. Allow a few seconds for the projector to sync up after pressing the button.


  • If you're using a PC notebook:

    • Press the function key on your keyboard that lets you display on an external monitor. It's often labeled with an icon such as , but it may also be labeled CRT/LCD. You may have to hold down the Fn key while pressing it. Allow a few seconds for the projector to sync up after changing the setting. Check your laptop's manual or online help for details.

      On most systems, the key lets you toggle between the LCD screen and the projector, or display on both at the same time.

      If you connect the notebook while the projector or computer are already turned on, the function Fn key that changes the computer's image signal to external output may not work. Turn the computer and the projector off and then back on again.


    • Depending on your computer's video card, you might need to use the Display utility in the Control Panel to make sure that both the LCD screen and external monitor port are enabled. See your computer's documentation or online help for details.
