MAINTENANCE

Symptom The projector does not respond to the infrared remote keypad...

CAUSE / REMEDY:

1.Does the built-in keypad work? If so, check that the keypads are enabled.

2.Does the green “Status” LED flash each time a key is pressed? If not, the projector is not receiving the keypad’s IR signals. Ensure the keypad is directed to either the front or rear of the projector, or towards the screen.

3.The viewing path between the IR keypad and the projector (or screen) may be blocked. Ensure there is a clear line-of-sight between the keypad and the projector (or screen).

4.The batteries in the IR remote keypad may be weak. Refer to page 2-17, Replacing Keypad Batteries for instructions on how to replace the batteries.

5.There may be unusual lighting conditions in the room affecting IR keypad operation. Determine if such conditions exist and correct.

6. The IR keypad may have been disabled for use with this projector(s). Press to enable broad- casting to all projectors. See 2.12, Keypad Protocols and Conversion and 3.7, Adjusting and Checking System Parameters for additional information.

Symptom The power is on but the lamp is not...

CAUSE / REMEDY:

1.Does the LCD status window say “warming up”?

2.The projector probably became overheated (there is likely an error code flashing and a mes- sage in the LCD status window). Allow to cool and make sure that nothing blocks projector vents. Do not operate in environments warmer than 35°C (95°F).

3.The lamp may have reached the end of its life. Check the “Lamp Hours” via RS-232 request ‘lph?’.

Symptom The display is jittery or unstable...

CAUSE / REMEDY:

1.If the display is jittery or if it disappears and reappears erratically, check that the source is prop- erly connected and that its signal is of adequate quality for detection. For example, it the projec- tor scans the default input for a signal to display, and a poor quality or improperly connected source is connected, the projector will briefly and repeatedly attempt to display an image. If no source is connected, the “No signal present” error message appears over a blank display. Correct the source connection.

2.The horizontal or vertical scan frequency of the input signal may be out of range of the pro- jector. Refer to page 5-1, Specifications for scan frequency ranges.

3.The sync signal may be inadequate. Correct the source problem.

4.The input signal type may conflict with the input module. Install/use the correct module for the source.

5.Pixel tracking, phase, filter, etc. may need more adjustment.

Symptom The display is faint...

CAUSE / REMEDY:

1.Check Input Levels option-turn auto to “off”, then “on” again.

2.Brightness and/or contrast may be set too low. Adjust as necessary.

3.Gamma may be set too low. Recommended setting for most signals is 2.2.

4.The projection room may be too bright. Lower the intensity of projection room lighting and reduce light reflections as much as possible.

5.The projector may be too far from the screen. Move the projector closer.
