Section 6: Troubleshooting

6.5.4 The Upper Portion of the Display Is Waving, Tearing or Jittering

1. This can occur with video or VCR sources. Check your source.
2. Check that the RGB Brightness setting is not unexpectedly low.

6.5.5 Portions of the Display Are Cut OFF or Warped to the Opposite Edge

Resizing may need adjustment. Adjust until the entire image is visible and centered.

6.5.6 Display Appears Compressed (Vertically Stretched)

1. The frequency of the pixel sampling clock is incorrect for the current source.
2. Sizing and positioning options may be adjusted poorly for the incoming source signal.
3. Check the geometry correction for warp or keystone correction.

6.5.7 Data is Cropped from Edges

1. To display the missing material, reduce image size to fill the display area available in the projector, then
stretch vertically to fill the screen from top to bottom. Add the anamorphic lens to regain image width.
2. Check blend settings and masking.

6.5.8 Display Quality Appears to Drift from Good to Bad, Bad to Good

1. The source input signal may be of low quality.
2. The H or V frequency of the input may have changed at the source end.

6.5.9 Display Has Suddenly Frozen

If the screen blacks out inexplicably, it is possible that excessive voltage noise on the AC or ground input has
interrupted the projector's ability to lock on to a signal. Power the projector down and up again.

6.5.10 Colors in the Display Are Inaccurate

The color, tint, color space and/or color temperature settings may require adjustment at your input source, or on
the web user interface Channel > Page2 menu. Make Sure the correct PCF, TCGD and/or Color Space file for
the source is used.

6.5.11 Display Is Not Rectangular

1. Check leveling of the projector. Make sure the lens surface and screen are parallel to one another.
2. Is the vertical offset correct? Make the necessary adjustments to the vertical offset on the lens mount.
3. Check geometry corrections settings, for example keystone adjustment.
