X2 OHP mounted on ceiling fixture. Image is dark on right side
Image from left to about two thirds of screen and then gets dark from top to bottom. The image can still be seen but is not good. Have changed lamp, cleaned external lens and repositioned image using fixtures and software control to no effect.Do I need to remove projector from ceiling mounting to gain access to internal pieces and what should I look for. The projector is about 5 years old. Thank you

Re: X2 OHP mounted on ceiling fixture. Image is dark on...
Yes it will have to come off the ceiling. It sounds like the light tunnel has collasped. This is located under the colorwheel. If you can get a new tunnel , be careful removing the colorwheel so no segments break off of it...make sure the new tunnel is pushed against the "lip" before screwing the tunnel clip back into place.

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/
It may be the internal backlight that is failing. When the display has failed but still has power, take a flashlight and hold it close to the screen, move the flashlight all around the screen and check if you can see anything. The display will be dark, but you should be able to make out the image that is there with the flashlight technique. If you can see an image on-screen, then your backlight has failed and you will need to replace the monitor. Weather or not you see an image is not a critical issue, but a tool to verify if the backlight is off or some other issue is causing the problem.
Note, it may be difficult to detect an image on the un-light display, for example if you have a dark image as your desktop background. So make sure to fully scan your display (top to bottom, and left to right covering the entire screen) with the flashlight technique in order to see any image on-screen.
Internally it has a inverter board which go bad sometimes or due to heat sometimes get unpluged.So you will have to open it make sure when you do there is no power going to it.Look at the wires make sure they are snug and try again.
Its an acrylic condensing lens inside the light engine that has melted/warped. You have to pullout the entire light engine then disassemble the optical light tunnel to get too the lens. Then you need a lens-smith to cut a new lens because Infocus won't stand behind this design flaw. Its really a shame on Infocus!
You can make several adjustments to improve your images such as lightening dark areas, changing the exposure, sharpening blurred edges, and changing the brightness and contrast.
Exposure adjusts the overall intensity of light in an image.
Adaptive Lighting improves only the dark areas in an image without affecting the bright areas.
Brightness adjusts the amount of light in colors ranging from light to dark.
Contrast adjusts the difference in brightness between light and dark areas of an image.
Sharpness helps define edges and the smoothness of texture in an image. Use this tool to make a blurred image appear more focused.
Adjusting the image
Follow the steps below to make adjustments:
Click the View tab and select the image you want to edit by either clicking the image, or by clicking the small box at the bottom left corner of the image.
Figure 1: Select the image
Click the Edit tab and then click the Advanced tab.
On the Advanced tools tab, click Adjust Image .
Select an adjustment from the list on the left.
Figure 2: Adjusting the brightness
The Exposure adjustment is automatically applied when the Adjust Image tool opens. Eight variations of the image are displayed on the left. The current image is displayed in the center. Each image represents a different level of adjustment. When you move the pointer over any of the images on the left, a large version of the image is displayed. Use Preferences to turn this large image preview on or off and to set the timing for the display.
If you want to use a different adjustment tool, select Adaptive Lighting , Brightness , Contrast , or Sharpness from the list.
Select one of the images on the left.
Do one of the following:
Click Accept to accept all changes and exit from the Color Toolkit.
Click Cancel to discard all changes and exit from the Color Toolkit.
If you have finished modifying the image, do one of the following to save your changes:
Click Save to overwrite the original image.
Click Save As to save the modified image with a different name.
the reflecting mirror is likely loose and falling down inside the light reflecting tube. you should have seen the band getting darker and larger, the small mirror is in front of the lamp and bends the light, remove the lamp and look down the tube (light path)
Don't recommend replacing the light tunnel if you never had any experience with DLP optical systems. you need to pay careful attention to the way you remove any screws or you will be forced disassembling the engine multiple time to get the alignment correctly.
