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 qualified 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. Make sure the shutter is OPEN.
3. Is the lamp ignited? It could take up to 3 attempts to strike a lamp. With a 90
second wait period in between each attempt it could take a total of 4.5 minutes to
turn the lamp on. Check
LAMP STATUS.
4. Is the correct input selected?
5. Is the source connected properly? Check the cable connections and make sure the
correct source is selected.
6. Can you access test patterns? Make sure there is not a full black test pattern
selected for display—press
Menu
to access test patterns, then cycle patterns
with
keys.
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.
