Section 6: Troubleshooting Mirage WU-L User Manual6-5020-100774-01 Rev. 2 (4-2012) 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 zero to ensure a visible image.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. 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.
6-6Mirage WU-L User Manual020-100774-01 Rev. 2 (4-2012) Section 6: Troubleshooting 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 Froze If the screen blacks out inexplicably, it is possible that excessive voltage noise on the AC or ground input has interrupted the projectors 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. 6.5.12 Display Is “Noisy” 1. Display adjustment at the input source may be required. Adjust pixel tracking, phase and filter. Noise is very common on YPbPr signals from a DVD player. 2. Make Sure the video input is terminated (75 ohms). If it is the last connection in a loop-through chain, the video input must 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.
Section 6: Troubleshooting Mirage WU-L User Manual6-7020-100774-01 Rev. 2 (4-2012) 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. 6.6 ArrayLOC 6.6.1 Cannot Find Color Adjustment Controls Use the color adjustment options under the ArrayLOC menu: access Main menu > Configuration > ArrayLOC. Color Adjustments by X,Y and Color Saturation options are not available for general use. They are part of the passcode protected Service menu. 6.6.2 Color/Image Settings Are Greyed Out To enable ArrayLOC: access Main menu > Configuration > ArrayLOC > Bright/ColorLOC Mode and set to Fixed, Cool, or Bright. If ArrayLOC is enabled: • ArrayLOC handles brightness and color settings, and overrides other color settings, for example Advanced Image Settings > Color Settings. •Main menu > Configuration > ArrayLOC > Array Color Target color settings are available for the master projector and are greyed out for all other projectors. To make your projector the master: access Main menu > Configuration > ArrayLOC > Synchronize to This Projector. Any projector in the array or BC group can be the master. The last projector to be set as the master is the master for the array (All) or BC group (Group). This setting is not saved between session. 6.6.3 Sensor Isn’t Calibrated (yellow alert) Sensor calibration must be performed by Christie accredited service technicians. Contact Customer Support. 6.6.4 Invalid Target Gamut (yellow alert) A color setting is not valid for the current color space, for example a white point is outside of the gamut. 1. Access the Array Color Target menu: Main > Configuration > ArrayLOC > Array Color Target. 2. Check XY settings for the colors. 6.6.5 Unable to Achieve Target Brightness/Gamut (yellow alert) A projector in an array that cannot achieve minimum brightness or target color space will disable BCLOC and cease contributing data to performance calculations. • Try lowering the target brightness or target color gamut settings until all the projectors can achieve the same performance. • If the discrepancy is too big, the light module may need to be replaced. Call Customer Support.

Check the “Synchronize to This Projector” menu item on the selected projector. Now, all other projectors will copy changes youmakeintheArray Color Targetor ArrayLOC Configurationsubmenus Adjust the colors in the image by selecting the desiredTarget Color Space. Adjust the brightness of the image by setting theRGB Brightness Target. If you wish the image to be as bright as possible, set theRGB Brightness Targetto a large number (such as 1000). Adjust the color of white in the image by selecting the desiredWhite Point. If aUser Whiteis selected as the white point then one of the following methods may be used to set the color of white. OR 2a2C 2D2E1B The “Target White x” and “Target White y” can be set the desired white color co-ordinates. The white may be adjusted to a black-body color temperature by checking “Set White to Color Temperature” and adjusting “White Color Temperature”. If aUsercolor space is selected then the colors can be adjusted by entering the desired co-ordinates into the “Target Red x”, “Target Red y”,etc. You can copy values from another color space to use as a starting point using the “Copy Color Space From” menu item.2B Step 2 – Set Your Array Color TargetStep 1 – Take Control of the Array Go to theMain>Configuration(4) >ArrayLOC(13) menu. This is the starting point for controlling ArrayLOC.1a Select theArray Color Target(4) submenu and proceed tostep 2. 1C When apreset (non-User) color spaceis selected thewhite point is fixedat6500 K (D65). To create a color space with preset primaries but a different white point, select a Usercolor space,then “Copy Color Space From“ the desired presetcolor space. TheUsercolor spacewhite pointcan then be adjusted as described instep 2D. Tip! Several controls in the Bright/ColorLOC Configuration andArray Color Targetmenus cannot be changedunless you take control of the array. Note! Display ared (or green or blue) test pattern on all projectors. On each projector, use theArrayLOC Projector Color Adjustments(PCA) “XXX Part of Red” (or “XXX Part of Green”,or “XXX Part of Blue”), to adjust the color red (or green or blue) to match the other projectors in the array (if necessary) Display awhitetest pattern on all projectors. On each projector, use theArrayLOC Projector Color Adjustments(PCA) “RedPartofWhite”,“GreenPartofWhite” and “Blue Part of White” to adjust the whitecolorto match the other projectors in the array (if necessary)Display awhitetest pattern on all projectors. On each projector, use theArrayLOC Projector Color Adjustments(PCA) “White Brightness Adjustment” (WBA) to adjust the whitebrightnessto match the other projectors in the array (if necessary). Increasing the WBA will make the projector brighter, decreasing the WBA will dim the projector. 2C 2A2B Step 2 – Fine Tuning of Projected Colors If measuring the projected colors and comparing them to the Common Gamutnumbers (shown in theArray Status), the guides at right indicate how to adjust the PCA to correct for differences. Look up the measured value compared to the Common Gamut. For example, if the measured red was 660, 325 and the common red was 640, 330, then the measured X was high (660 > 640) but the measured Y was low (325 < 330). Using thetable for red (top table at right),look up “Low X” and “High Y” - it indicates that the “Green Part of Red” needs to be increased (or made positive). ArrayLOC – Bright/ColorLOC Tuning Guide Step 1 – Go to the ArrayLOC Menu Go to theMain>Configuration(4) > ArrayLOC(13) menu. This is the starting point for controlling ArrayLOC. 1A Select theProjector Color Adjustment(5) submenu and proceed tostep 2.1B High Y -+ Low Y -+ RedLow X High X High Y ++ Low Y -- GreenLow X High X High Y +-- Low Y ++- BlueLow X High X Once adjustments have been made to one target color space, they are usually a good starting point for other color spaces. Select the other color spaces and then use the “Copy Adjustments From” menu item to copy the adjustments from the color space that was tuned. Tip! Repeat this procedure for each projector that appears to not match the others in the array.2D Projector Color Adjustmentsare specific to each projector so changes can be madewithout taking control of the array by leaving boxunchecked. Tip! Projector Color Adjustmentsare specific to each color space, so when the selected Target Color Spaceis changed the adjustments from a previously tuned color space should be copied (see Tip below) to the adjustments for the new color space and if necessary, projector tuning repeated. Note! Follow this procedure only if the brightness or color matching between projectors running ArrayLOC does not meet your satisfaction. Before continuing, check that the mismatched projectors are properly running ArrayLOC by verifying theirprojector addressappears listed in theArray Statusdisplay. Note! ArrayLOC – Changing Projected Image Colors (Primary & White)Mirage WU-L ArrayLOC Bright/ColorLOC Setup – Do Nothing!The default configuration of a Mirage WU-L projector hasArrayLOC enabledand configured to display a reasonably saturated gamut at the maximum brightness the array can support. Unless one wishes to adjust the color of the primaries or whites, there isno need to do anything else. If one does wish to change the primary or white color, proceed to theChange Projected Image Colorsguide. If the projectors within the array do not seem to display matching white colors, white brightness or primary colors, then proceed to theTuningguide.

This is the starting point for controlling ArrayLOC. 1A Select theArray Color Target(4) submenu and proceed tostep 2. 1C Calculate the Expected Brightness by converting theRGB Brightness Target value from step 2A into the desired unit using the selected RGB Brightness Target Unit. Forexample,iftheRGB Brightness Target was set to 47 and the selected RGB Brightness Target Unitwas 0.1 ft-L, then the expected brightness would be: Expected Brightness= 47 * 0.1 = 4.7 ft-L 3A Step 3 – Changing RGB Target Brightness Unit Measure the projected white brightness. Update theWhite Brightness Adjustment(WBA) as follows: New WBA = Old WBA * (Expected Brightness/ Measured Brightness) Repeat step 3B until the measured brightness is sufficiently close to the expected brightness. 3B Set theRGB Brightness Targetto a value approximately half the brightness of the dimmest projector in the array. Set the value to approximately half of the white brightness capability (WY)ofthe projector flagged “w” in the Array Status. Ensure theArray Capabilityshows “W100.0”. This indicates that the array brightness is equal to the RGB Brightness Target. Note theRGB Brightness Targetvalue–it will be used to calculate the expected brightness in step 3. Move to the theArrayLOC Projector Color Adjustments(PCA) menu. Display awhitetest pattern on the projector. 2A 2C Step 2 – Setting the RGB Brightness Target Select a projector you wish to adjust first. Set this projector to “Synchronize to This Projector” by checking the box.1B Select a desiredunitfor the RGB Target Brightness. The range of theRGB Brightness Target control is 1 to 2000. For example, if one wished to control the array brightness in ft-L and wanted to control the brightness in steps of 0.1 ft-L, then a unit of 0.1 ft-L would be appropriate. After completing step 3 with this unit, if an array brightness of 8.0 ft-L was desired then the RGB Brightness Targetwould be set to 80 = 8.0 /0.1. 2B This is anadvanced procedureintended only for users who desire to control or monitor their array brightness inspecific units(for example lumens, ft-L, etc.). Users who want the projectors to operate as bright as possible do not need to use this procedure. This procedure requires an external light meter. Note!
