Mits HD1000 front fan gringing, any suggestions?

1101 Views 3 Replies 3 Participants Last post by  dreamstate
Title pretty much says it all. The front fan in my HD1000 is making that grinder sound, like a high pitched whine. It's getting really loud. It's the same in Standanrd, and low lamp mode. I've got roughly about 1200 hrs on the bulb.

Anyone had this problem and solved it?

Thanks in advance!

Well the quick simple answer is......bad bearing......get a new fan. Easy enough to replace.
You must still be under warranty. I would get it fixed under warranty.
Yup, I'm going to have to.

I tried stopping the fan in the front that I thought was making the noise and when it stopped the whine continued, although 1 second after that the bulb shut down. When I opened it up to find the fourth fan that I was thinking should be there it was buried under a circuit board and I won't go in there. I'm thinking it's the color wheel making the whine as this happened with my Benq 6200 as well but went away.

So I'm gonna have to live with it.

Something really strange happened though when I went to replace my batteries in the remote. I took out the Mitsubishi ones in there and stuck new Duracells in. They didn't work. Tried another pair, those didn't work, and so on. 6 brand new pairs later I tried them in other devices and they worked. Then I tried Energizers, they worked.
