It is the color wheel i have a similar problem and am looking for the part, the color wheel is a small electric motor that spins at a high speed and it can go bad. which will lead to the horrible squeel/hum/buzz.

Does the color wheel noise stop when the projector is is first turned off and the fan is still running? What is the cost to have this replaced or did you find a place to get the motor replacement.

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.

Good Luck!

My Infocus DLP 4805 can't turn on
very possible the lamp is bad. Many projectors will not even power on once the lamp burns out. As for the strange noise, there may be something more serious wrong with it.

Buzzing noise, trying to open the cover
It sounds like a piece of your colour wheel has fallen off. You will need to take the front panel off (2 screws) plus the two plastic rings around the lens pull out. Be careful not to snap a circuit that sticks out behind the remote sensor on the front. I've had this problem a few times but have just glued it in with 24 hour drying glue, the noise i had was so loud it was hard to watch anything, plus i lost the red colour to the picture until i glued it back in.

Infocus 4805 - Doesnot display and make noise at start-up
Well a single red blinking means the lamp won't strike after five (5) attempts. The "squeaking" sound if it's coming form the large fan usually always means the Mos-Fet fan speed controller chip has failed which presents sometimes as an intermittent squeaking sound. Which would implies the lamp may have failed from the resultant over temp. However if the squeaking noise is coming from the color wheel that would mean it's bearings have failed and if is is unable to phase lock at reference speed the lamp would also not strike. The odd symptom is the remote thing... That does not fit! If is actually is related to the common cause of all the problems... That leaves only the power supply has partially failed (not too expensive) causing all of these symptoms.

Or murphy has moved in...

Good luck!

Projector stays on for 3 minutes then turns itself off
Hi Chipped Rice

The loud buzzing noise you heard was the colourwheel that gave in.

Now what happens is , the machine will turn on and go through the whole cycle and as soon as the colourwheel is supposed to start doing it's stuff the Projector will switch off because there is no response from the coulourwheel itself.

You will have to replace the colourwheel unfortunately as it cannot be fixed.

Thanks for using Fixya !

Infocus SP4805 buzzing noise
Hi dcabbarno

The buzzing noise is a broken colourwheel and the shadow could be a part of the colourwheel that is obstructing the light engine or it could be your packlight pipe ( tunnel with 4 tiny mirrors in it ) that was damaged when the colourwheel broke.

I do unfortunately not have the part numbers of the parts that I mentioned , but you could assist by opening up the unit and supplying me with the part numbers.

The colourwheel you will spot straight away once you've taken off the top cover of the Projector , the packlight pipe is situated right next to it - looks like a small tunnel that's got 4 mirrors inside it - takes the light into the light engine.

Once you've supplied me with these I can get you prices and places to order it from and will help you with instructins on how to replace them - it is quite easy to DIY.

Thanks for using Fixya !

Loud noise
It's probably the colorwheel not the fan, can only be fixed by replacement.

projector lights up, but only half of the picture is clear, the other half is obscured, there is a (yellowish) line in about the middle. Left side of that line is projected but behind a dark veil. this was after a shift of venue and after just putting in a new bulb (7 hrs).
