Question about Mitsubishi ColorView XL30U Multimedia Projector

1 Answer

Yellow area in the projected image

Our ceiling mounted XL30U is displaying a yellow area in the projected image that covers about 20% of the left top corner of the screen. It is like someone painted the lens of the unit with yellow spray paint. Is it worth repairing or is it too major? Thanks for the help.

Re: Yellow area in the projected image

Hello Media Man,

Looks like your projector has done it. Thats acommon trouble to ageing polirising lens, usually the blue. less blue, the green and red make up the yellowish image on the screen. The blue is bombarded with tremendous heat from the lamp and it fade and wash out. If its free, its worth replacing. Get quote for the poliriser; 2 pieces each color.
Good Luck.

My image is upside down after I mounted my projector to the ceiling

There are projection mode settings which will allow you to adjust the orientation of the image. Adjusting this setting will rotate the image so that it is not displayed upside down when attaching the projector to the ceiling.

To activate this setting:

  1. Press the Menu button on the projector.
  2. Using the Arrow buttons, select the Image icon on the left side.
  3. On the Image screen under the Projection label, select the icon that represents ceiling mounted projection. Note: You may see both front and rear ceiling mounted projection modes. You may choose which ever best suits your needs.
  4. Press Menu on the projector controls to exit the settings menu.

Mounting the Projector from the Ceiling

Projectors, in general want to project the bottom of the image 1 foot above the lens at a typical range. When mounted upside down, they project the top of the image 1 foot below the center of the lens. If you don't want to turn the projector over, you'll have to change the angle and probably go to the extreme on the keystone correction.

I have a viewsonic pj500 projector which has functioned perfectly for 5 years. Now the area around the image area either shows a dark blue with dark stripes and the image area has a yellow cast which seems...

LCD projector 101, your blue device is dying inside of projector. Consider purchasing a dlp based product, they do not suffer from color decay.

Really you are blessed , most lcds last about 3-4000 hours or 4 lamp changes. good luck

The filters are starting to show their age. This is a normal occurance for projectors and is the result of heat. The filters and/or the mirrors might need to be changed.

Dark Area Growing on Right Side of Image

It isnt the lens. There is a crystal asembly that the light is reflected thru after it hits the color wheel. It is 4 pieces of completely mirrored glass glued into a small metal holder. One of those pieces has shifted. To fix it, you can take it out and possibly have a jeweler repair it. It is difficult to take out, but it is doable. Feel free to contact me if you need to. email is (bill @ baerwalde . com) Just remove the spaces.
