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.
Try turning colour correction OFF. (button in up position). See what affect the iris control has. This control will changed the color of the slide from deep red at nearly closed to washed-out blue and white. at full open. I adjust the controls for each slide. The color temperature of the 8549 lamp varies with the brightness. lower level warmer, higher cooler.
i think the LCD has been set to a very high brightness set the LCD brihtnes lower from the settings..
better more is to reset the camera to the default settings this would set the aperture, shutter, Exposure, LCD brightness and other settings to defaults and this would save from any unwanted changes than required
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.
