Question about InFocus ScreenPlay 4805 Multimedia Projector

1 Answer

Projector stays on for 3 minutes then turns itself off

I bought the Screenplay 4805 a year and a half ago and love it. The other day I heard a loud buzzing noise and a few minutes later the projector turned itself off. Since then, I have been unable to turn it on and leave it on. It turns itself off in about three minutes. I know the bulb is good. I've only used aobut 80 hours of it. Can you help me?

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 !

Screenplay 4805 not anything. I plugged it in, heard a pop, and then tried to turn it on, and nothing happened. No fan, no light. Could this be a fuse?


Yes, it could be the glass fuse on the power supply/ballast. If you remove the top cover you should see it clearly if it has blown.

My projector is making loud buzzing noises that arent normal.. I just ceiling mounted my projector its an InFocus ScreenPlay 4805 and the bulb has 1500 hours on it. The buzz started after it was on for 30...


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!

Projector makes wierd noise and shuts down after several minutes


3 problems: 1- the light tunnel is collaping and needs replacing. 2- the tunnel might be hitting the colorwheel, which is now making that wierd noise. and 3- it needs cleaning. these models are famous for these 3 problems. there are no filters, so the dust just gets sucked in. the glue on the tunnel wears out from heat after a while. the colorwheel motor also wears out from heat and dust. the parts are not that expensive and they are relatively easy to install. contact an infocus authorized service center (from their website) and either get these parts or send it in.

tunnel- 306-0095-01
colorwheel- 525-0146-00

Try pressing the "auto image" button on the projector itself. This usually will correct the sync problem.

InFocus 4805 lost red


Yes Geoff, What has happened is one of the two red glass filters on the color wheel has separated and flew off which was the snap you heard. So white light is in half of all parts of the spectrum that require any red.

There should also be a vibration now that can be felt on the projector and possibly heard as well.
I suggest not running it again until this is repaired as more damage could result. If you have the skills and the part that flew off isn't destroyed it can be carefully glued back in place and problem solved. I have seen quite a few of these glass filter segments survive this.

Good Luck!

Infocus screenplay 4805 not communicating with PS3 console.


Try pressing the "auto image" button on the projector itself. This sometimes solves these types of problems.
