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.
Image appears "squeezed" or vertically stretched into center of screen
1. Check your Resizing selection.
2. The anamorphic lens (optional) may be needed for this source.
The projector is on but there's no display...
1. Was a lens cover accidentally left on? Remove lens cover.
2. Make sure the shutter is OPEN.
3. Is the ballast on? Check the breaker position to make sure the ballast is on.
4. Is the lamp ignited? Check for interlock problems such as an open lamp door.
5. Is the correct input selected?
6. Is the source connected properly? Check the cable connections and make sure the
correct source is selected.
7. Is AC power connected?
8. Can you access test patterns? If so, check your source connections again.
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 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 for scan frequency ranges.
3. The sync signal may be inadequate. Correct the source problem.
The display appears unusually dim or faint...
1. Brightness and/or contrast may be set very low.
2. The source may be double terminated. Ensure the source is terminated only once.
3. The source (if non-video) may need a different sync tip clamp location.
4. The lamp may not be properly aligned in the projector. Use LampLOC
adjustment in the Lamp Menu.
The upper portion of the display is waving, tearing or jittering...
1. This can sometimes occur with video or VCR sources. Check your source.
Portions of the display are cut off or wrap to the opposite edge...
1. Resizing and/or blanking may need adjustment.
The display appears compressed (vertically stretched)...
1. The frequency of the pixel sampling clock is incorrect for the current source.
2. Resizing, vertical stretch and positioning options may be improperly adjusted for
the incoming source signal.
3. You may need an anamorphic lens for sources that have been supplied in a re-
sized and vertically stretched format.
