SOURCE: Projector displaying yellow tint in center of screen.

The yellow tint is probably coming from the lens. It could be that the glass is tempered or possibly just needs to be cleaned.

Yellow tint


Hello. Here's the visual key to remember about projectors--LCD panels show their colors like this: RED lcd panel displays cyan onscreen(baby blue); GREEN lcd displays purple; BLUE lcd displays yellow. ( You now know where the displayed dust is!) The problem is most likely a burned blue lcd or polarizer filter in front of the blue lcd panel. This occurs when the dust filter isn't cleaned regularly or properly and heat builds up--yes, enough to "cook" the lcd panel or actually cause a burn to develop on the polarizer. The polarizer is just like a lens in a pair of good sunglasses. It is a small, extremely thin, pane of glass with polarizer material glued onto one side. When burned, it causes a "shadow" effect--that enhances the display of that particular color--in this case, yellow.--Hope I was of assistance!---Rick

Dell 2400 MP DPL Projector projects a yellow tinted image.


Clean any external dust filters or air openings in the unit.If you don't want to remove the filters, you can simply use a vacuum cleaner hose to suction away the dust from the filter element--same effect anyway. The unit probably does indeed need a thorough cleaning.
The yellow effect is most probably a burned BLUE polarizer filter located behind the blue LCD panel. (Color key--Purple onscreen=green lcd, baby blue onscreen=red lcd, and yellow onscreen=blue lcd). That's how you can tell which lcd has dust on it! Usually, the green lcd has the most free area around it and collects the most visible dust. (large purple specs) The polarizer filters can get burned due to excessive heat (not keeping proper ventilation). Of course, it might be the blue LCD panel which is failing prematurely due to heat build-up over time. The polarizer filter isn't that expensive if it can be replaced, however, the actual lcd panel IS.---Rick

Same problem w yellow on viewsonic pj550


Yellow is the mixture of 100% red and 100% green. what you may have here is a blue LCD failure in the machine. Try this to check. Open up PAINT and double click one of the colors on the bottom. now click add custom color. then in the RGB section put 0 for red 0 for green and 255 for blue. ok out of everything and fill the background w/ the blue. it should be a VERY intense blue, if its white or or kinda blue, you have an LCD issue

Welcome to the disapointing world of LCD projection. Your blue device is dying and thus allowing the green to come through instead of combining for white. I suggest buying a dlp product they are immune to this color decay problem. Good luck

Color Problem


I think that projector used three different LCD panels with red, blue and yellow. You probably have a damaged red LCD panel, and if so, it is not worth getting the projector fixed. Those panels were really expensive back then.
I once had that red problem with a projector and it turned out to be a bad connection on one end of the "computer to projector" cable. Borrow one from a friend and see if it solves the problem.

Projectors screen turns yellow,on and off,after awhile has been looking white


You are describing Color Decay. Welcome to the world of LCD projectors. The blue device is the first to go, thus the yellow fringe. You must have about 3-4000 hours on the projector. Replace the product with a dlp product and it will last a lifetime, or until you want something with newer features.
