If you bought locally, I would take back to the store and swap it out. If you bought it on the internet, contact UPS or who ever delievered it and contact the company you bought it from. Save everything, box, receipt, packing slip, etc..

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.

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.

HL-P5063W Constant buzzing when on or off


The clue is you hear it with the set off, most likely a transformer or coil in the standby power supply, not unheard of (no pun) for this type of part to actually vibrate hard enough to make a unpleasant sound that can be heard.

Troubleshooting consists of finding (listening) the culprit and either replacing the part or in many cases Hot glue applied (some if a small coil or transformer will use super glue on the copper coils) to the exposed wires on the part.

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

I PUT MY SONY GRAND WEGA KF-42SX300U 50 in. lcd


Well we need to have in mind that a generic lamp will give you 3500 to 4500 lamp hours and the Phillips will give you 6000 to 8000 lamp hours ,The lamp itself typically uses AC current and about 15,000 volts to ignite the lamp's mercury2.gif vapor gas. The gases inside the lamp react when electricity charges up the mercury gas creating very bright light. The voltage drops to keep the flow of electricity to the lamp.
The symptom of a bad ballast is that you could hear a constant CLICKING or electrical BUZZING sound,my recomendation is to take out the lamp to physically check for any sings,(shatter fillement,black or grey spots in the fillement or smoke ) you can get good deals at http://www.discount-merchant.com/?click=52978
Please keep us posted,

My Grand Wega KF60WE610 has no picture and has a buzzing sound when turned on. If left on the green light blinks and the buzzing sound may or may not occur again. Can anyone diagnose this issue?


That buzzing sound is this kind of Tv LCD Projection, is most likely a issue with the ballast (only if sound cames near the lamp) you can check that just follow the cables that are connected to the lamp, take out the back cover of tv, and keep pushing the switch cover (if not tv will not turn ON). and check if that sound comes from the only board connected to lamp. if it does, you are going to need a ballast very soon.

Phillips 32" LCD TV, Sound through TV speakers has a buzzing noise which is steadily getting more aNNOYING AND LOUDER.


We are having the "buzz" problem with our new 42' Phillips LCD too.

We do not have a sound system yet...but have read they have the same problem, so I won't assume when I get a sound system it will go away. What I did do for now...and it helped..

Go to the SOUND portion of TV menu
Choose EQUALIZER
Turn down the two FAR RIGHT columns, they are the treble. It helped us.
