5 Troubleshooting

If the projector is not operating properly, note the symptoms and use this 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”.

5.1 Displays

5.1.1 The projector is on but there is no display

1. Was a lens cover accidentally left on? Remove lens cover.

2. Is the lamp ignited? It could take up to 5 attempts to strike a lamp. With a 30 second wait period in

between each attempt it could take a total of 2 minutes to turn the lamp on. Check

LAMP STATUS.

3. NOTE: After striking the lamp, it can take up to 5 minutes to achieve full brightness.

4. Is the correct input selected?

5. Is the source connected properly? Check the cable connections and ensure the correct source is selected.

6. Can you access test patterns? Ensure there is not a full black test pattern selected for display—press

to access test patterns, then cycle patterns with

keys.

7. Check EM and PHM connection.

5.1.2 Severe motion artifacts

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.

5.1.3 The display is jittery or unstable

1. 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.

5.1.4 The display is 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. Adjust

LAMP POSITION to optimize the position of the lamp for maximum brightness.
