Fan making noise

Hi, my projector is working great, but the fan is making some noise and buzzing. Is this something that I could fix myself?

    I also have a weird buzzing noise, but I know it's not the fan. When changing image modes (ie, if the projector changes resolutions from 480i to 720p) or when only black is displayed (such as when movies fade to black for transition), the buzzing calms until the next scene appears.

    I may try a new bulb assembly because after the bulb turns off during the cooldown period, the buzz is gone while the fans are still pulling air out of the unit.

    buzzing noise when it gets hotter. Doesn't take long for the buzzing sound to come. I have air to blow out. I going to take the bulb out first. Build up on a fan blade could be the noise, or a broken blade or worn out fan blade from getting to hot. Just a guess. I could not take the top off. White powder on the inside screen of the bulb unit.

Hi, you probably have something rubbing against the fan or a faulty fan. To investigate, you'll have to open up your projector and look at the fan.

To start the process, you'll have to remove the cover of the unit. I just opened my Sharp xr-10x DLP projector today, which had no power, no lights, no functions. A previous post worked for me...Remove the 6 screws on the bottom of the unit (you'll need a longer phillips) and the two screws on the back, toward the top of the unit. Obviously, be sure to keep these handy for reassembly (I have two curious dogs and a 4 year old to contend with). Then, to remove the housing...use a std screwdriver and slightly pry the cover off from the rear of the unit. This should losen allowing you to pivot the cover forward and then off from the projector lens. Once removed, look toward to rear of the projector...the fan is located's a small unit that vents out the rear. Before removing this, check to see if there is any debris in the vent area that will be need to be removed. If you need to remove the fan, you can do so with the screws attached to the fan unit. Once this is done, you'll be able to plug the unit in and see where the noise is coming from. If it is from the fan unit itself, you'll have to order a replacement from Sharp. Just contact their service/warranty dept and tell them the make/model and they can obtain the part for you. At this point, reassemble the unit by reversing the above instructions. At least your projector should work while you await a replacement part to arrive.

Good Luck...Hope this helps you out.

Projector makes lots of noise

Yes, that can solve the problem because there's also a possibility that the lamp is the one that is causing the noise..

Hope that helps........

I replaced the lamp and the projector is make a very loud buzzing noise. How do i remedy this problem?

There may be a fan rubbing against a cable or something, but more than likely there is a vibration damper clip that has come loose off of the colorwheel and will have to be fixed by a technician.

I have a one year old epson ex51 and was working great until last night. Since last night the fan noise has increased significantly. Does anyone know how to fix the fan noise?

Mine just started doing that too. I'm pretty sure the fan blades are rubbing against the casing. If you have had it for under a year, call and get it fixed, but if its over a year you're on your own. I nudged the fan with a metal hanger, and it has stopped making noise. I think eventually I'll need to take it apart and get a new fan for it that has better bearings.

Color wheel sounds like a buzz saw. Fan is quiet because there is no noise in the cool-down mode. Can this be replaced by user?

Baily, I have had my HC1500U color wheel replaced two times due to the color wheel's unpleasant "buzz saw" effect showing up every few thousand hours of usage. It is happening again for the third time and I am still within Coscto's warranty so I am going to have it replaced again...will never buy a DLP projector again...too many moving parts that can break!

Would love to be able to replace it myself if you ever find a place that sells the color wheel.

My projector was working fine then a error message came up saying to check airflow. The temperature light and the lamp light are on as well. Is this something I can fix myself? If so, how? Thanks....

the projector is probably dusty. the dust keeps in the heat that the projector is trying to expell. use canned air to blow out the dust. also, check to see that all of the fans are working. if one of them is not, replace it.

Dell 2200pm making noise

Most of the screws are accessible from the bottom of the case. Put the projector on its back and use a thin Phillips. There may be one other screw hidden on the side that has a plastic cover on it. Once you have loosened all the screws you can find, turn it over and try to lift the top part of the case. If there are still screws in place, you will be able to find them by seeing at which part the case does not wiggle as you try to lift it. That helps you find where the two halves are still attached and where the remaining screws are.

I have a 2200, but it is in the shop because it turns on and right off, and nobody could help me fix it. When I get it back, I might be able to help you find all the screw points.

Your fan has probably dried up and needs a drop or two of oil on the shaft where it goes into the motor.

An option if you cannot open the case is try to find the point where the shaft goes into the fan motor, and spray a little WD-40 at that spot using the red hose that comes with the can. If you get it at the right spot, the noise should lessen or go away completely.

Dramatic increase in fan noise

Hi there

If you place your hand on the machine and you can actually feel the vibration , you might be looking at a faulty Colourwheel.

If not , try cleaning the fans by blowing it out. If the problem still occurs you might have to replace the fans.

Horrible noise

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.
