Re: buzzing sound

Very few fan problems with this unit but a fan is a possiblity. Most likely the color wheel is the problem. This part can be replaced but is difficult and requires considerable dissasembly and then a difficult alignment process. Reccomend an RCA auth. service center for this repair.

In some cases the buzz is external. The vibration of the unit may just cause a tray, flat surface, or other surrounding attachments to rattle and buzz. Look for anything that may be loose or laying on or about the TV.

I can help but as I said this model has a LOT of chronic problems.

Loud sound would be coming from defective color wheel that is mounted i light engine, next to lamp housing. Replacement of color wheel is required expertise/ experience and professional will do that for you in correct and in safe manner.

We have a constant buzzing/whining noise when the TV is on.

Is it a whuring or buzzing sound? When color wheels go bad they can make a lot of mechanical nose, cooling fans can do the same but they do not spin as fast as a color wheel does
