Non-cinema Displays

The following troubleshooting entries assume that you are using a 3rd-party input source for displaying
alternative non-cinema material. As a first step, always consult the documentation supplied with the external
equipment.

5.6.1 The Projector is ON but There's No Display

1. Was a lens cover accidentally left on? Remove lens cover.
2. Make sure the douser is OPEN.
3. Is the lamp ignited? Press the lamp button on the Touch Panel Controller.
4. Is the correct DVI display button selected on the Touch Panel Controller?
5. Is AC power connected?
6. Is an active source connected properly? Check the cable connections and make sure the alternative source
is selected.
7. Can you access test patterns? If so, check your source connections again.

5.6.2 The Display is Jittery or Unstable

1. If the non-cinema display is jittery or blinking erratically, ensure that the source is properly connected and
of adequate quality for detection. With a poor quality or improperly connected source, the projector will
repeatedly attempt to display an image, however briefly.
2. The horizontal or vertical scan frequency of the input signal may be out of range for the projector. Refer to
Section 6: Maintenance from the CP2000-SB User Manual (020-100162-xx) for scan frequency ranges.
3. The sync signal may be inadequate. Correct the source problem.

5.6.3 The Display is Faint

1. Brightness and/or contrast may be set too low.
2. The source may be double terminated. Ensure the source is terminated only once.
3. The source (if non-video) may need sync tip clamping.

5.6.4 The Upper Portion of the Display is Waving, Tearing or Jittering

This can sometimes occur with video or VCR sources. Check your source.

5.6.5 Portions of the Display are Cut Off or Wrap to the Opposite Edge

Resizing may need adjustment. Adjust until entire image is visible and centered.

5.6.6 The Display Appears Compressed (Vertically Stretched)

1. The frequency of the pixel sampling clock is incorrect for the current source.
2. Sizing and positioning options may be adjusted poorly for the incoming source signal.
3. Use an anamorphic lens for typical HDTV and anamorphic DVD sources that have been re-sized and
vertically stretched via 3rd-party software.
