Section 5: Troubleshooting

5.5.8 Display has Suddenly Frozen

If the screen blacks out inexplicably, it is possible that excessive voltage noise on the AC or ground input has
interrupted the projector's ability to lock on to a signal. Power down the projector and then power back up
again.

5.5.9 Data is Cropped from Edges

To display the missing material, reduce image size to fill the display area available in the projector, then stretch
vertically to fill the screen from top to bottom. Add the anamorphic lens to regain image width. Cropping could
also be due to the screen file selected that has cropping configured. In both scenarios, refer to the
Setup: Screen File Setup Window, on page 3-40

window.

source is selected.

5.5.11 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
is offering 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 Specifications
3. The sync signal may be inadequate. Correct the source problem.

5.5.12 The Display is Faint

1. The source may be double terminated. Ensure the source is terminated only once.
2. The source (if non-video) may need sync tip clamping.

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