MAINTENANCE

Symptom Colors in the display are inaccurate…

CAUSE / REMEDY:

1.The color, tint, gamma, color space and/or color temperature settings may require adjustment. Review all settings, and refer to 3.6, Adjusting the Image and 3.7, Adjusting System Parameters and Advanced Controls.

Symptom The display is not rectangular…

CAUSE / REMEDY:

1.Check leveling of the projector. If necessary, try relocating the projector or screen so that the lens surface and screen are approximately parallel

2.Is the vertical offset set correctly? Adjust as necessary using the vertical offset knob on the front of the projector.

3.The "Vertical Stretch" option may need adjustment. Also check pixel tracking.

Symptom The display is "noisy"…

CAUSE / REMEDY:

1.Display adjustment may be required. Adjust pixel tracking, phase and filter.

2.The video input may not be terminated. Make sure the video input is terminated (75 Ω). If it is the last connection in a loop-through chain, the video input should be terminated at the last projector only.

3.The signal cables carrying the input signal may be of poor quality. Use only good quality sig- nal cables.

4.The distance between the input source device and the projector may be too great. If the dis- tance between the input source device and the projector is greater than 25 feet, signal amplifica- tion/conditioning may be required.

5.The input signal may be of poor quality.

6.If the source is a VCR or off-air broadcast, detail may be set too high. Keep near 4 for most sources.
