I'm experiencing a loud buzzing (fan?) sound that just started recently while watching my HLP5674W. The picture is fine, but the sound of what may be a fan or something like that is very loud and will only stop after the set has been turned off for a few seconds. I've turned the TV on and off several times and the buzzing comes back each time. Any idea what this is and how to fix it? Thanks!

pull the light assembly out clean it with a vacuum and some pressurized air spray and place it back in the TV, while it is out check the fans on either the inside or in the removable assembly for damage or other interference in operation...If this doent help dissemble/remove the rear of the enclosure ( 6-10 screws) and clean the insides carefully and then turn the tv on - being careful not to be touching ANYthing and see if you locate the culprit.....

Mine is doing the same thing. I think its the cooling fan. The bearing is probably gone.

are the fan blades bent causing a vibration. you can run the fan with the cylinder off to try and isolate the noise. Let me know

This sounds to me like it could be the color wheel or the ballast of the unit. The bulb is always the first step, but it depends on what kind of buzzing you're hearing. The ballast will usually click to ignite the lamp, while it may also buzz when it's not functioning. The color wheel will also buzz if it gets stuck, or rattle when pieces inside are broken.

Check this buddy..

The fan could have an obstuction. I have heard of tech sheets getting into the fan and causing a vibration and vibrating sound.

Their is no more you can do.

the loud buzzing noise isnt the xbox its the powerbox the one tht you plug the power cord into b4 u plug it into the back of the xbox when the buzzing happened to me i just shook it and it went away

Sounds like the cooling fan blades are hitting something (possible worn bearings).
