My Super Easy Dust Blob Fix for the AE2000

So I got my first dust blob on my AE2000 today and all I did was take my CO2 air blaster and insert in in the vent fins on the front of the projector. Just lightly blew it out starting at the top slot and working my way down on both sides pointing inward toward the lens. VIOLA... No more dust blob. The CO2 blaster is nice cause theres no danger that you'll get a blast of cold liquid like you get with canned air. In addition it's not a super strong blast of air. Here's what I use:

Hope this helps.

Elio,

I'm wondering if this will work for other projectors or is it dependent perhaps on the placement of the air vent as each projector is different in this regard?

In other words, if you can't get to the lens through the vent fins then this probably won't work.

Does this air blaster work in short blasts or continuous or do you even have that choice?

But won't that be a pain if you have to keep doing that?

Good tips Elio. I am sure this will help a lot of people if they ever experience a dust blob.

Sounds to me, however, that you have just as much chance "adding" dust as removing it.

You can do short bursts or continuous ones. It's a really nice air blaster.

It's possible. But probably a lot less than opening the unit and exposing the entire interior to a potentially dusty environment. Don't forget you can get that nozzle pretty deep into the projector. Can't imagine it's going to pull in any more dust than is already in there.

I can't see any harm in it as a first procedure to try. I don't know anything about CO2 blowers, but if it doesn't work or you get even more blobs as a result of doing it, you're looking at sending it in anyways. If it fixes it, you've saved yourself a hassle.

I found my first dust blob on my AE3000 so I went out to Circuit City and got the CleanDr C02 blaster.

I had one noticeable green blob on a black screen when all the lights were turned down.

I stuck the nozzle into each front vent slot closest to the lens and gave a short burst. It worked like a charm! The noticeable blob is gone. If you focus all the way out, there are still a few small dust particles, but when the picture is focused for normal viewing, you don't see any of those.

Is CleanDR CO2 Blaster only available in the USA?

To help prevent dust being carried back into the projector from the exhaust fins, you could do this procedure with the projector on and fan running on high (as in high altitude setting). This would also allow you to monitor the image for real-time results.

Well, unfortunately this didn't work for me.

Also looking at the projector internal layout, (PT-AE3000), It would seem difficult to get the CO2 nozzle close enough to the optical components to actually dislodge any dust.



I think I'm left with trying to have it professionally cleaned or daring to do this myself on a new projector. I did that quite often with a much less expensive InFocus X1 years ago which was also prone to dust blobs.

Not sure... you might be able to find something similar in a different brand if it is.

Did you do it on both front vents?

I think it probably just stirs up the air enough to possibly shift the dust particles.

I might have to give it a try with the projector on and see how the particles move depending on where the CO2 blower is inserted.
