Dell 2400 MP DPL Projector projects a yellow tinted image.
In recent weeks, at least a couple of times, the lamp light comes on and shuts down the projector. However, after waiting a brief time, turned on and everything was correct. There is a high concentration of dust in the building (remodeling a warehouse for a church building in Central Amercian nation of Honduras, Tegucigalpa).
The night before the problem arose, we watched the soccer game of Honduras/Trinidad and Tobago and their was zero problems.
What are the possible causes of this? I have read several forums on the internet, but nothing that directly addresses this projector.
Yellow tint is constant and not patchy. I suspect that it needs a thorough cleening, but do not know where nor how to do this. They sell air compressed in a can for cleaning electronics here, but I really don´t want to open the machine up for any reason and do inintended damage.
I do a lot of PPT in sermons and song lists and yellow tint makes photos make people look like they have a severe case of Malaria.
Hence, I need help. Warranty is no longer in effect.

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

I too use the projector for songlist and had the same cbc identical problem. I thought maybe the bulb was about to go. I noticed however that the yellow tint would only appear when the cord that transfers the image to the screen was plugged to the computer. I replaced with a new cord I had handy and that did the trick..Thank God.

Hello, it sounds like the lamp has gone bad, it's gone interminent to the point its like a flasher in your cars blinker system. If you remove it, you might see if it's discolored to a blueish tint instead of a shiny silver mirror finish. On those with the small lamp it can be harder to see. the lamp number is XL-2400.....tks
Lamp is burned out or makes a popping sound. When the lamp reaches its end of life, it may burn out and may make a loud popping sound. If this occurs, the projector does not turn back on. To replace the lamp, see on page 38. LAMP light is solid amber If the LAMP light is solid amber, replace the lamp. LAMP light is blinking amber If the LAMP light and the Power light are blinking amber, the lamp driver has failed and the projector will automatically shut down. If the LAMP light is blinking amber and Power light is solid blue, the color wheel has failed and the projector will automatically shut down. Unplug the power cord after 3minutes then turn the display on again. If this problem persists, contact Dell™. TEMP light is solid amber The projector has overheated. The display automatically shuts down. Turn the display on again after the projector cools down. If the problem persists, contact Dell™. TEMP light is blinking amber A projector fan has failed and the projector will automatically shut down. If the problem persists, contact Dell™.
I think this is a lamp issue. Even though your lamp might have an advertised time of 3000 hrs from Dell, it can fail and dim a lot earlier than that. Often within 1000 hrs a projector lamp's brightness can be reduced by up to 40%. Projector lamps brightness and lamp life varies according to how you use your projector and the environment it is in. Our company sells projector lamps and has created a YouTube video to help people get the most out of their projector lamps. You can see the video below. If you decide to buy a new lamp we have the lamp you need in stock at Projector Lamp Experts.
I am experiencing a similar problem with mine. It will cycle on and off without actually powering up fully and then after about the 4th or 5th time it will shut off completely and the lamp indicator light on top illuminates. i am reading in other blogs that this is a design flaw on this unit. let me know if you have found any fixes.
the lamp is not at problem, but the dlp engine is at fault, u may have to replace it.since u bought it 2nd hand,it is not worth changing the same as it will cost u more than ur buying price.when u plan to buy ur next projector, make sure u buy a new one as it will come with a fresh lamp & manufaturers warranty on the unit & at 4000 / 5000 hours of projector usage is guaranteed!
