Power
6.3.1 Projector Does Not Power ON
1. Ensure that the projector is plugged in.
2. Ensure that cables are connected and not damaged.
6.4
Light Module
6.4.1 Light Module Suddenly Goes OFF
1. Check the shutter setting - if status display shows SH then the shutter may be active. Toggle through
shutter modes. In gray shutter mode it should be possible to display menus.
2. Verify that the RGB Brightness is set sufficiently higher than 0 to ensure a visible image.
3. The DMDs may be overheated. Check for an alarm condition.
6.5
Displays
6.5.1 The Projector Is ON, but There Is No Display
1. Make sure the lens cover is removed from the lens.
2. Make sure the correct display button is selected in the channel setups.
3. Make sure AC power is connected.
4. Is an active source connected properly? Check the cable connections and make sure that the alternative
source is selected.
5. Make sure that the DVI cable from the PHM to the EM is connected.
6. Are the test patterns accessible? If so, check source connections again.
6.5.2 The Display Is Jittery or Unstable
1. If the non-cinema display is jittery or blinking erratically, make sure that the source is properly connected
and of adequate quality for detection. With a poor quality or improperly connected source, the projector
repeatedly tries to display an image, however briefly.
2. The horizontal or vertical scan frequency of the input signal may be out of range for the projector.
3. The sync signal may be inadequate. Correct the source problem.
6.5.3 The Display Is Faint
1. The source may be double-terminated. Make sure that the source is terminated only once.
2. The source (if non-video) may need sync tip clamping.
3. Check RGB Brightness setting and Brightness Uniformity control.
4. If the Twist software was used, test by disabling the blend.
