I have a Christie LX100 Projector when projecting a white image there is some yellow tint. Is this something that can be fixed?

If the yellow tint is uniformly over the whole screen then try changing the video colour tint, hue, phase and other chroma related settings in the menu.

I have a VT465 and the projection back ground is yellow and I can't get it to be white

If you are talking about the actual image that is coming from a laptop being yellow instead of white, then this is caused usually by a bad signal cable running between the computer and the projector.
To be more specific: All colours in a projector get made up in some way between red, green and blue. White is all of these colours at maximum, yellow is made by red and green at maximum but no blue. If your image is Yellow when it should be white, then the blue signal information is not reaching the projector. This can also happen within the projector or computer itself but is less likely. If your using a VGA cable (15 pin cable) then blue is run through pins 3 & 7 (positive and negative respectively), see if your cable is either missing these pins on either end or if they are bent, although it's more than likely within the cable itself. You can test this theory easily by trying to put something blue on screen, if the blue signal isn't getting through then it'll appear black.
If changing the cable doesn't solve the problem try testing the computer by trying to use a different one, and test the projector by plugging in a monitor or another projector.

If you are getting a yellow screen without sending signal and just trying to get the "no signal" or "no input" screen white, then this won't be the case.

Sir, its white small dots on complete screen, like sky with stars,

Place a white piece of paper about 1000mm in front of the screen and focus the image sharply.
Choose menu, image, advanced then select color manager.
go through the color options and check if some pixels are permanently on or off (ie small dots or black) instead of a uniform colour on the screen.

The DLP chip is most likely the faulty component

Dark horizontal bands appear on projection

Your matrix is failing. If the unit is under warranty, send it back.

The matrix is the bit that allows light to come through of each colour. If its failing one colour won't get through. If the circuitry is failing, more than one colour wont get through.

Connection Identification, experiencing no Sound

Thank you for your help I visited a Sony retail outlet yesterday and they explained that to obtain sound you have to go through a sound system using the red connection because they is no sound / speakers build into the projector.
