I have a loud buzzing noise on my Toshiba DLP 46" projection TV. It is not the fan, it works fine. In fact the TV works great and has a good picture. The buzzing used to go away after awhile. Now it...


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.

Samsung model HLP4663WX/XAA with loud buzzing noise, need to know which part to replace.


See attached photo: you have a bad color wheel----it turns at about 12,000 rpm and bearings in the tiny motor go bad.

High pitched or fan like sound is classic symptom.

The wheel is available on the internet and You Tube has video instructions by model number for replacing it---Google the model number for the part number for your set to locate the part and instructions.

This for most people is a do it yourself job---takes like 45 minutes start to finish.

If color wheel slows too much set will shut down as its speed is monitored and the wheel can even shatter causing shutdown of the set.

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...


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.
Contact local tv repair shop to get color wheel replaced in tv.
Thanks.

My TV model #HD50LPW628YX2 is buzzing I do get a picture, and the buzzing gets quieter after 30 sec of being on


Well that buzzing sound usually can be 2 things. First of all a color wheel but you have a good image, so there's a possibility it might just be the fan. If you start getting funky colors then it would be best you replace that

Loud Buzz


loud buzz is the color engine, turning the color wheel. Find instructions on how to take it out and clean it and that should fix that problem.

Toshiba 56HM195 56 in HD DLP Loud Buzzing and color distortion


If the sound, sounds more like a Hum with some vibration chances are the Cooling fan located behind the lamp is going bad, about $20 to repair, if its a high pitch hum most likely the Color Wheel and if thats the case about $30.
Good luck, my fan just went bad now seeing green dots everywhere, so debating on just junking it out or fixing it, with winter coming on might just breakdown and buy LCD and say the heck with DLP from now on.
Good luck to you..

Loud humming or high pitch buzzing noise coming from my rca dlp tv 50 inch


I have a very high pitched sound and when I move the tv it will stop for a second or two and then start again. The sound sometimes stops all together. But very high pitch sound.
