Values in Color Saturation slidebars vary over time
1. Once defined, Color Saturation slidebar values fluctuate over time and will likely
be different upon subsequent visits to this menu. This is normal and should be
ignored, as these changes do not redefine the x/y coordinates or color gamut.

The display is not rectangular...
1. Check leveling of the projector. Ensure the lens surface and screen are as parallel
to each other as possible.
2. Is the vertical offset correct? Adjust as necessary using the vertical offset knob.

The display is "noisy"...
1. Display adjustment at your input source may be required. Adjust pixel tracking,
phase and filter. Noise is particularly common on YPbPr signals from a DVD
player. (If using a PC source, adjust using a high-frequency test pattern with one
pixel on/off throughout.)
2. The video input may not be terminated. Ensure the video input is terminated
(75Ω). If it is the last connection in a loop-through chain, the video input should
be terminated at the last source input only.
3. The input signal and/or signal cables carrying the input signal may be of poor
quality.
4. If the distance between the input source device and the projector is greater than
25 feet, signal amplification/conditioning may be required.
5. If the source is a VCR or off-air broadcast, detail may be set too high.

1. If the lamp won't ignite, there may be an interlock failure such as an open lamp
door, or failed lamp fan. An error code will display on the status LED display
located on the built in keypad.
2. If a temperature is too high ("DMD over critical temp limit", e.g.), the lamp will
not ignite until the temperature is low enough. Cool the projector and try again.
3. For suspected communication failures, power-down the projector and try again.
4. If the lamp does not ignite after a second and third try, replace the lamp.

1. Try increasing the lamp power.
2. The DMDs may be overheated.
3. Replace the lamp.

1. Increase lamp power, if possible.

1. Ensure "Intensity" is selected in the Lamp menu. Other lamp modes disable
LiteLOC™.
2. If the lamp power has increased to its maximum in order to maintain a
LiteLOC™ setting, LiteLOC™ is automatically terminated. If the values shown
in the Lamp menu indicate that the lamp power has reached this "over-drive"
state, either reduce your LiteLOC™ setting or install a new lamp.
