2nd update - Cuz came 'round, put humpty dumpty back together again and the sound is still there. Upon further research I found that the clear segment is missing on the colour wheel (someone else has this same problem) anyways removed the colour wheel and held it in my hand and found that it vibrates like my wifes favourite toy so somehow I'm gonna fashion a new segment out of sticky back plastic and a fairy liquid bottle like they used to on blue peter cos Optoma quoted me £150 for the repair! Wish me luck....
Update: I opened mine up and found a segment of the color wheel had snapped off. Maybe it was blocking something..I can't put the projector back together though so waiting till the weekend for my cuz to do it for me...I'm glad cos my lamp is only a month old.
I don't think it's your lamp. My lamp is only a month old and it did the same thing last night after I mopped my room with lots of water and let it dry naturally (I increased the water content in the air by a lot!). Anyways I tried my old lamp and the same noise is still there.... Anyone else?
It's the lamp. The same exact thing happened to me, my projector started making a loud whinning noise and the picture quality got really dim. At first i thought it was the fan too but after alittle online research i found out that that when the lamp bulb shatters it does this, so i went a got a replacement and it fixed all the problems. :)

If this sound you are describing is NOT constant and is intermittent in nature it is certainly not a color wheel problem. This sound is usually caused by failure of the Lamp cooling fan (the large one)'s Mos-Fet driver chip. Located on the bottom of the main board. These surface mount "chips" do fail and it's a fairly common problem however this is usually (but not always) accompanied by the projector shutting itself down after a few minuets or so as the high temp switch trips off. A color wheel common failure presents in two ways, either all the glass color filters fly off (there are six) and the image is monochrome (black and white) or just one or more of the segments has come off and the result is an imbalance of the color wheel which spins VERY fast resulting in a vibration that is constant and can easily be felt by placing your hand on the projector. And all of these problems are very easy to repair.

The DV10 has a futuristic-looking outer casing and two internal
speakers located behind a silver grille mesh at the rear. Heat is
removed through its side ventilation and the internal fan has a noise
level of 27dB, which is comparable to a loud computer and quite
distracting when watching movies at low volume. At 368 x 117 x 273mm,
the unit is small enough to permanently and inconspicuously reside on a
this is from a review .
it sounds like that the fan needs to be cleaned the sound you hear is normal but if it sounds like its racein the moder might be on its way out if you have a can of air used to clean a key bored i would try to clean it out with that if not take it to a repair place to see if they could look at the moder
This is a faulty colourwheel that will have to be replaced as a colourwheel cannot be repaired.
It is quite easy to replace and I would suggest you to do it yourself if this unit is no longer under warranty.
All you'll have to do is get your hands on the new colourwheel from your local or nearest retailer.
To open this projector, you need to undo six screws at the underside of the case. That means you have to turn the projector upsidedown.
Pls note that one of these scews is a little hidden under the carrying handle.
After removing the screws, return the projector to it's normal 'up-side' up, standing position.
Remove the bulb cover srews and remove the bulb cover.
Lift up the top cover carefully starting from the front then all together.
The cooling fan is mounted very near the bulb assembly.
Carefully check the fan blades for any obtacles, wires or even a broken fan blade, that could be causing the noise.
