5.1 POWER
5.1.1 Projector Does Not Power ON
1.Ensure projector is plugged in? Check power switch above power cord is in the ON position.
2.Check that the Status LEDs are ON. While the projector is busy initializing, the LEDs should be 
cycling. When finished initializing, the Power and Shutter LEDs (the two on the right) should be on. 
3.Check the LCD display. While the projector is busy initializing, the display should show “Please 
wait”. When finished initializing, the display should show “Standby mode”.
4. Check the LCD display for any warnings or errors.
5.2 LAMP 
5.2.1 Lamp Does Not Ignite
1.Is there an interlock failure? Check the LCD display for an error. If the other lamp has ignited 
and an image can be seen, use the remote keypad and check the Sta tus menu for any errors and for 
the Lamp door interlock status. If not lamp has ignited, use the Virtual OSD on the web interface to 
check these items. The interlock failure could be an open lamp door or a failed lamp fan.
2. If a DMD temperature is too high, the lamp will not ignite. Cool the projector and try again. 
Ensure there is proper ventilation. If an optional exhaust is used ensure it has adequate airflow. Using 
the remote keypad or Virtual OSD as above, check the lamp mode in the Lamp menu. This may be 
set to a single lamp or dual lamp mode. Check in the Status menu what the reported mode is.
3. For suspected communication failures, power-down the projector and try again.
4. If the lamp does not ignite after the second attempt and after powering down and up again 
(complete AC power down, then replace the lamp.
5.2.2 Lamp Suddenly Turns OFF
1. Check lamp power through the remote keypad checking the Lamp menu or from the web user 
interface Advanced: Lamp menu. Try increasing lamp power. 
2. The DMDs may be overheated. Check for an alarm condition on the LCD keypad display.
3. Replace the lamp.
5.2.3 Flicker, Shadows Or Dimness
1. Check lamp power through the remote keypad checking the Lamp menu or from the web user 
interface Advanced: Lamp menu. Try increasing lamp power.

5.2.4 LiteLOC™ Does Not Seem to Work
1. Ensure LiteLOC™ is set and enabled in the Advanced: Lamp menu, via the web user interface or 
using the remote keypad check the Lamp menu.
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.
5.3 LCD 
5.3.1 Blank Screen, No Menu Displaying 
1. The LCD should never be blank regardless of power state. 
2. Press any arrow key on the built-in keypad. The backlight on the LCD and the backlight for the 
built-in keypad should turn on. If the LCD is still blank, restart the projector.
5.4 REMOTE KEYPAD
5.4.1 Remote Keypad Does Not Seem to Work
1. Replace the batteries. 
2. Check if IR signals are received by the projector. Pressing any key on the remote control towards 
the front or rear sensor, the PWR status LED will blink, regardless if any command is executed. If the 
LED does not blink, restart the projector.
3. Ensure the remote keypad is enabled. If the projector is powered, using the built-in keypad, open 
the OSD menu and go to the Main Menu>Configuration>Communication submenu and check the 
checkboxes for Front IR Enabled and Rear IR Enabled are checked. Enable them if they were 
disabled and try again.
4. Projector is busy. If the projector is busy in a warm-up mode or in a cool-down mode, the 
commands from the remote keypad may be ignored. Wait until the projector reaches a stable state 
(Power ON or Stand By) and try again.
5. Press the PROJ key on the remote keypad. If this brings up a pop-up box on the OSD, ensure that 
the checkbox is marked to enable the projector.
6. Using the XLR connector, use the remote as a “wired” keypad. If it does work and all the IR 
sensors have been enabled, then there may be a problem with the IR sensors.
5.5 OSD 
5.5.1 The OSD Menu does not display  
1. Using the LCD, ensure that OSD Menu is enabled, scroll down until the item OSD is displayed. 
LCD read “OSD : off” press and hold the OSD soft key on the built-in keypad. The LCD will read 
“OSD on” and press Menu key

remote keypad.
5.6 ETHERNET
5.6.1 Trouble Establishing Communication with Projector
1. Ensure any address changes have been saved, and reboot to implement. If you still have trouble 
establishing communications with a projector added to an existing Ethernet network, the projector’s 
IP address is likely in conflict with another address already in use. Contact your network 
administrator.
2. Ensure Ethernet settings are valid for the site. All devices should have the same subnet mask yet 
unique IP addresses.
5.7 DISPLAYS
5.7.1 The projector is on but there is no display
1. Was a lens cover accidently left on? Remove lens cover.
2. On the LCD display, check that the shutter is open. This will also be indicated by the shutter LED 
being green.
3. Is the correct input selected. Check cable connections. 
4. Check if menus appear on the screen.
5. Can you access test pattern? Ensure a full black test pattern has not been selected for display, press 
Menu to access test patterns, then cycle patterns with keys. Check your source connections again.
5.7.2 Severe Motion Artifacts
1. Most likely there is a synchronization problem with reversed 3-2 pull-down in 60Hz-to-24Hz film-
to-digital conversion in your source. Correct at the source.
2. Set the projector to run in Free fun. Open OSD menu and go to Input Switching & PIP. Ensure that 
running mode is set to Free run not to Frame Lock.
3. Display a test pattern on the screen, pressing the Test button on the remote keypad. The test pattern 
should be displayed correctly. If not, contact your dealer for assistance.
5.7.3 Image Appears ‘Squeezed’ or Vertically Stretched into Center of Screen

M-Series User Manual5-5020-100009-01 Rev.1 (07/08)
5.7.4 The Display is Jittery or Unstable
1. If the display is jittery or blinking erratically, ensure that the source is properly connected and of 
adequate quality for detection. With poor quality or improperly connected source, the projector will 
repeatedly attempt to display an image, however briefly.
2. The horizontal and vertical scan frequency of the input signal may be out of range for the 
projector. Refer to Section 6 Specifications
 for scan frequency ranges.
3. The sync signal may be inadequate. Correct the source problem.
5.7.5 The Display is Faint
1. Brightness and/or contrast and/or gamma may be set incorrectly.
2. The source may be double terminated. Ensure the source is terminated only once.
3. The source (if non-video) may need a different sync tip clamp location. 
5.7.6 The Upper Portion of the Display is Waving, Tearing or Jittering
This can occur with video or VCR sources. Check your source.
5.7.7 Portions of the Display are Cut OFF or Warped to the Opposite edge
Resizing may need adjustment. Adjust until entire image is visible and centered.
5.7.8 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. Use an anamorphic lens for typical HDTV and anamorphic DVD sources that have been re-sized 
and vertically stretched, via 3rd-party software.
5.7.9 Data is Cropped from Edges
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.
5.7.10 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.
5.7.11 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 down the projector and 
disconnect from AC. Then plug in again and power up as usual.

Section 5: Troubleshooting
5.7.12  Colors in the Display are Inaccurate
1. The color, tint, color space and/or color temperature settings may require adjustment at your input 
source. 
2. Try Auto Setup.
3. Ensure signal connections are correct.
4. Ensure the proper channel for this source is being used.
5.7.13 Values in Color Saturation slide bars vary overtime
1. Once defined, Color Saturation slide bar 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.
5.7.14  Display is Not Rectangular
1. Check leveling of the projector. Ensure 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. 
5.7.15  Display is “Noisy”
1. Display adjustment at the input source may be required. Adjust pixel tracking, phase and filter. 
Noise is particularly common on YPbPr signals from a DVD player. 
2. Ensure the video input is terminated (75 S). 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.
