Symptom:

Colors on the display are not accurate (when using the
Multi-standard Decoder).

Cause/Remedy:

1) Color and tint settings may require adjustment.

Symptom:

The display is not rectangular in shape.

Cause/Remedy:

1) The geometry settings may not be set correctly. Adjust the display

geometry settings. (Press

for the Geometry menu).

Symptom:

The display is “noisy.”

Cause/Remedy:

1) The input may not be terminated. Make sure the input is terminated

(75

Ω). If it is the last connection in a loop-through chain, it should be

terminated at the projector (only).

2) The signal cables carrying the input signal may be of poor quality. Use only

good quality signal cables. Madrigal Imaging cables are recommended.

3) The distance between the input source device and the projector may

be too great. If the distance between the input source device and the
projector is greater than 25 feet, signal amplification/conditioning may
be required.

4) There may be interference from other equipment. Keep the projector

away from devices which radiate electromagnetic energy such as motors
and transformers. Common sources of these are slide projectors, speak-
ers, power amplifiers, elevators, etc. Keep 35 mm slide projectors at least
two feet away from the projector.

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.

Modified display settings are not being saved in the active setup memory.

Cause/Remedy:

1) Is the active setup memory locked? Press

to display the Source

Message. If a

is displayed, unlock the setup. (Press

.)

2) ASR is set to On for the current input memory and an ASI was

automatically performed due to mismatched scan frequencies.

Symptom:

The display is OK when displaying the crosshatch test pattern (

) or status

screen (

) but when trying to display a source, nothing is visible.

Cause/Remedy:

1) You may not be selecting the source correctly. Refer to section 3.3,

Source Selection, for source selection instructions.

2) The source may not be connected properly. Verify that the input source

is active and check the cables between the source and the projector.
