Can Not Establish Communication with Projector

1. Ensure any address changes have been saved, and reboot to implement. If you still have trouble
establishing communications with a projector added to an existing Ethernet network, the projector IP
address is likely in conflict with another address already in use. Contact your network administrator.
2. Ensure Ethernet settings are valid for the site. All devices should have the same subnet mask yet unique IP
addresses.

Displays

4.7.1 The Projector is ON but There is No Display

1. Was a lens cover accidently left on? Remove lens cover.
2. On the LCD display, check that the shutter is open. This will also be indicated by the shutter LED being
green.
3. Is the correct input selected? Check cable connections.
4. Check if menus appear on the screen.
5. Can you access test pattern? Ensure a full black test pattern has not been selected for display, press Menu
to access test patterns, then cycle patterns with keys. Check your source connections again.

4.7.2 Severe Motion Artifacts

1. Most likely there is a synchronization problem with reversed 3-2 pull-down in 60Hz-to-24Hz film-to-
digital conversion in your source. Correct at the source.
2. Set the projector to run in Free run. Open OSD menu and go to Input Switching and PIP. Ensure that
running mode is set to Free Run not to Frame Lock.
3. Display a test pattern on the screen, pressing the Test button on the remote keypad. The test pattern should
be displayed correctly. If not, contact your dealer for assistance.

4.7.3 Image Appears 'Squeezed' or Vertically Stretched into Center of Screen

1. Run auto setup, pressing A
2. Check your resizing selection.

4.7.4 The Display is Jittery or Unstable

1. If the display is jittery or blinking erratically, ensure that the source is properly connected and of adequate
quality for detection. With poor quality or improperly connected source, the projector will repeatedly
attempt to display an image, however briefly.
2. The horizontal and vertical scan frequency of the input signal may be out of range for the projector. See
Section 5 Specifications
3. The sync signal may be inadequate. Correct the problem at the source.
