The message NO SIGNAL is displayed.

An image source not connected to the projector is selected, the signal is not being output from the computer, or the signal is not reaching the projector. Make sure the connectors are securely attached to both the projector and the image source. Then check that the image source is selected correctly. When NO SIGNAL is displayed, you cannot access the projector menus.

A black screen is displayed.

The computer signal cannot be interpreted by the projector. Verify the display format (see page 57). Wh en you see a black screen, you cannot access the projector menus.

The image or parts of the image are blurred or not in focus.

Turn the focus ring on the projector to see if this improves the image. Also check that the projector is within the recommended distance for the size of the screen. (See the table on page 4 for more information.) For the sharpest images, the projector must be perpendicular to the screen and the projection surface must be flat.
