If the projector does not appear to be operating properly, note the symptoms present and use the following guide to
assist you. If you cannot resolve the problems yourself, contact your dealer for assistance.
NOTE: A Christie accredited service technician
is required when opening the projector to diagnose any “probable
cause”.
The projector is on but there’s no display...
1. Was a lens cover accidentally left on? Remove lens cover.
2. Ensure the shutter is OPEN.
3. Is the lamp ignited? Check for interlock problems such as an open lamp door OR
check for light spillage out the back.
4. Is the correct input selected? Check cable connections.
5. Check if menus appear on screen.
6. Can you access test patterns? 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.
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.
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.
